Another good reason to use Dev-Editor for rendering only is that things get broken as people work on it, so depending on when you sync some stuff might not work or may crash :p
Also if you're using a git client to download the repo, make sure it grabbed the dev-editor branch and not the default (master) @snow spire , I don't think the latest set of changes have copied up to master quite yet
snow spire
I've never used git so might either just get the zip download or convince my wife to show me how to git stuff
scenic frost
Hey all, is im looking for a way to give the end user the ability to create a custom camera path and export video/stills from a simple scene, is that possible?
tight stone
@scenic frost With some C++ work you can build one yes;
scenic frost
Is there any documentation or tutorial u know of that could help me? @tight stone
tight stone
You can look at the FrameGrabber.cpp / FrameGrabberProtocol.cpp to figure out how to capture the viewport, you can look at the ImageWriteQueue/ImageWriteTask (or ImageSequenceProtocol) to see how to write image sequences to disk. You can just build a camera path with whatever gameplay logic you want (spline components?)
Then set the engine to use fixed framerate, and walk along your spline each frame while capturing the viewport to image sequence.
Don't expect it to be realtime though
scenic frost
i appreciatae the help, i dont expect the capture to be real time, ive used sequencer a bit to know there is some lag
tight stone
The png writer is the slowest portion in simple scenes surprisingly. If you write .bmp files you can actually write out to disk at 30-60fps in empty scenes :p
scenic frost
good to know, thank you again

I gave compiling the dev/editor branch a go last night but no dice I'm afraid. I might need to post some highlighted screenshots to check if I've set things correctly but firstly it did seem to error on stuff like datasmith, seems like they're disabled etc. Do I need to do anything like compile the master branch before grabbing any of the other branches I have no idea how to really use visual studio I'm afraid.
tight stone
@snow spire Try to only build the UE4 solution.
snow spire
yep, chose that. over on the top bar, what have you got set in startup solution and what right click options on teh start buton (no idea if they're even important)

@snow spire do you know which commit you downloaded? Looks like the branch doesn't build right for us either starting this morning at 10am eastern

@tight stone Completely random, were you part of Interlopers?
Now for my question, here I'm trying to animate a plane flying then crashing in sequencer. You can see that it's got a pretty sharp turn and tends to jolt when using linear interpolation between the points. Cubic (auto) interpolation is nicer but isn't great to use because the object your'e animating eases in and out in speed instead of being relatively consistent. Is there a better way to do this? Should i just add more key frames and use linear?
tight stone
@snow spire Hmmn. If you post the build log on gist.github.com I can take a quick look
@alpine jetty yes; Also curve editor + editing the tangents
alpine jetty
I was Jangalomph on Interlopers. PM me if you'd like to catch up. :D
-snip- I think i found the curve editor
tight stone
If you convert them to cubic or break handles (select + right click on keys) you'll get tangent handles that you can drag to change the shape of the curve
alpine jetty
Much smoother, thanks!

@tight stone try this link <script src="https://gist.github.com/28DavesLater/ec1d0ac9781d6ba1819755c086c1af25.js"></script>

@snow spire if you don't need datasmith you can probably just go into the Engine/Plugins/Enterprise folder and delete DatasmithCADImporter (well, move it to your desktop or something in case you need it)
And then re-run GenerateProjectFiles.bat
snow spire
hmmmm.... my current project I was hoping to test did use datasmith but... to do some basic look at the render features outside taht project I could do that
here's a snapshot of what else i have set which I'm not even sure is correct....
this line in the github instructions was abit confusing too: After compiling finishes, you can load the editor from Visual Studio by setting your startup project to UE4 and pressing F5 to debug.
cant see a place to set my startup project to UE4
tight stone
BuildAgent is the wrong startup, you want UE4, but that compile error is in an engine plugin anyways so if you wanted to use it you'd have a problem :p
If you right click on UE4 in the Solution Explorer, you can choose "Set as Startup Project"
snow spire
ah.... see I kept clicking on startup projects but couldnt see UE4 only unrealbuildtool
didnt realise you could add it from right click..... this is why us tech artists stay away from compiling π
FYI my preoject uses datasmith from max exports so not necessarily the CAD stuff
tight stone
Not sure why it doesn't build to be honest, maybe just update to the latest source again in a few days when it does build, but fingers crossed you don't need it right now
snow spire
alright, so build seems to have worked and is loading UE4 now - sitting at the 45% mark as is traditional
there was a fleeting glimpse of a yellow warning in the generateprojectfiles.bat command line warning...something something datasmith but it was gone while I bliknked and it built anyway
tight stone
Probably a warning about something referencing it but not found, hopefully another plugin doesn't rely on it
When you open your uproject it'll probably compile more and you might still run into problems
snow spire
so another noob question.... do I need to build it on each machine I might want to test on?
tight stone
If you copy the whole build folder around probably not
snow spire
cool, cos theres a threadripper with a 2080ti that want to do some raytracing
tight stone
Should have compiled on that threadripper!
snow spire
danger will robinson
So... seems to have booted up... and made a project for me... where should I start looking for some of the right dials to tweak for stuff like better AA etc... is there anything forward facing or is it all under the hood? looked under the sequencer render setting but nothing obv there... Project render settings? Post Process? Camera settings?
tight stone
@snow spire window Cinematics Movie render Queue
Drag a sequence in, click the settings, click plus setting in the top left, anti-aliasing
The raytracing setting doesn't do anything yet
Optionally save your settings to an asset for reuse later by pressing the Preset button in settings editor
tight stone
Yeah works up to 16k. Set output resolution in output, set tile count to 8, overlap to 0.1
Takes a bit right now, 30min for 15360x8640 @ 32 spatial samples
Should work around timeouts/memory limits on large images, some caveats (no taa, bloom/convolution bloom don't work, ssr and other screen based effects may not)
snow spire
still interesting direction.
the whole movie render queue looks promising too. especially the linking of sequences to levels, very handy
pass rendering? couldnt see it in there?
tight stone
Composure and GBuffer channels not in yet
The level linking thing only works with remote renders right now, but should work with local ones soon
snow spire
remote just means close down UE4 and open a new process correct?
tight stone
Doesn't have to close but yeah
You could write your own distributed rendering implementation
And change in the project settings what the button does
So that studios can write a deadline implementation or otherwise
snow spire
nice. deadline is our render manager of choice so interested to see how that might be hooked into at some point.
tho the scale of out rendered projects within UE4 and the speed we can output them from one machine slightly makes distributed a non-issue currently....
should have scare quoted "currently" on that one
tight stone
I'm sure you'll find some settings in the new tools to increase those times :)
snow spire
lol. I'm sure I will π
not sure if this is in your wheelhouse, but we previously made a VR Previz / storyboarding tool for a film that came out last year (production was mid 2017 tho so a while ago) I'm going through and updating our setups and trying to figure out the feasibility of our virtual camera being rendered / raytraced on a second machine and being network sent live back to the virtual monitor in the VR setup.
so the VR side runs smooth and looks ok but the camera sees a more realistic view
tight stone
You might be able to put something together using the pixel streaming support in the engine (though I don't know if it's intended to ingest the results of it). Sending the position of the virtual camera to both machines and then sending the pixel data from one to the other is plausible, but I don't know how much latency you would have which may or may not be a deal breaker
snow spire
yeah thoughts I've had on it were to show the live render target but send off position updates to the second render slave and pull back frames either on request or on an interation to show better frame. not a deal breaker if cant be made to work as backup plan is just to offline render all the shots outside of VR session...ala through movie render queue.
FYI here's our self indulgent making of / behind the scenes for the film. https://vimeo.com/359446829

Matt I was recently watching a conference from epic that recently happened and the guy said something about sequencer which I didn't understand can u get some insight on it pls
swift bridge
@unkempt ravine set your editor to cinematic
but specifically raytracing is a different beast.
go into your main light and set hte cascades to 3-4 and the shadow draw distance as far as you need it
yes
that will at least lod bias everything to highest settings.
well. what you are asking doesnt really have 1 answer
thats the problem
depending on your scene it has many answers. π
i do large world landscapes. There is a specific solution for that in distance fields and dynamic lighting
you might need a different solution. I am not sure. π
there are some handy commands as well... for example.
r.ForceLOD 0
yep
i get what you mean
but its not one answer.
that command above will force everything to always draw on the highest LOD level.
open the console with you "~" key
unkempt ravine
thanks
swift bridge
foliage.ForceLOD 0
if you need that to draw at lod 0 as well.
and setting the number of cascades in the main light to 3-4 and choosing an appropriate distance to draw out to willl give you crisp shadows.
tight stone
@calm jackal if you have a question ask the question and if someone knows the answer they will help

I believe it only controls the HUD class in the GameMode which isn't used by a lot of games @unkempt ravine

It's about the new sequencer addition that they showed I didn't quite understand it

you basically just repeated yourself banishingshift... how about adding more detail so others don't have to do research and at least know what you are talking about in case they have an answer for you?
"something's new and I don't understand" won't make people want to explain things to you
snow spire
@tight stone So starting to play with a real scene with the 4.25 features, I dont suppose there's any concept of a virtual frame buffer where you can render temporary single frames with all the render queue settings? basically if you want to see what the AA is doing before rendering your sequence etc?
calm jackal
Oh wait I can do something better I can just share the clip can't i
tight stone
@snow spire No. You can make camera cuts that are 1 frame long though and add your sequence multiple times to the queue and use different settings for each job? (caveat: not well tested)
Using different output string formats you can put the results into different folders at least.
(You could also trim the playback bounds down to a single frame... or try playing with Output > Custom Frame Range, though i'm not entirely convinced the upper bound setting on it works properly)
rose pine
is it possible to have a single trigger volume both play and reverse a sequence?
like player overlaps trigger, sequence plays to the end, then the same volume overlapped again reverses the sequence. Having a hard time trying to work this out (im a total noob with graphing)
tight stone
@rose pine Make a boolean that tracks whether or not the sequence has played forward. On Volume Enter:
if(bHasPlayedForward == false) { Sequence.Play(); bHasPlayedForward = true;
else
Sequence.PlayReverse(); // I forget the node names, maybe set speed to -1 and play?
Depends on the exact behavior you want wrt retriggering / interrupting the cutscene

@tight stone started some renders and maybe got a tad overenthusiastic with how many samples I added for a first test at 4K. Are you normally mixing temporal and spatial samples and are you usually leaving of overriding TAA when doing all this?
tight stone
@snow spire in general; dump time into temporal sampling, it gives you the same anti-aliasing as spatial sampling but you get nice motion blur out of it instead. If you go above 8 samples (temporal&spatial combined), turn off TAA. TAA will only give you 8 unique positions for the 'jitter', so after that point you're not gaining much quality
Don't think you should use TAA with spatial samples, you can get away with using TAA with temporal, but again once you > 8 samples it's not worth having TAA on
snow spire
awesome... great starting advice
tight stone
Do you want 4k as your final render resolution or are you planning on downresing to 1080?
snow spire
downsampling to 1080 for current applicable projects - but who knows after that
tight stone
I'm not entirely convinced you need to downsample if you're using supersampling (Temporal/Spatial)
snow spire
it was a wonder of mine.... put time into 4 x sample rate
tight stone
Since every time the camera is offset you get new data that wasn't there before (such as a bright spot from a reflection) that will influence the final pixel as appropriate
snow spire
so is teh temporal sampling some sort of step along the distance the frame would travel based on the shutter angle?
i.e. so 16 samples would be a sample every n/16
tight stone
Yes; We take the shutter angle (as defined by the 'Camera' setting, 180 by default) and split the timestep up to be 1/n * shutterAngleFrac time
so with a 180 shutter angle and 4 ts, each sample 1/8th of a frame in duration
snow spire
any bias or jittering on that?
and being a center motion blur its backwards and forwards in time?
tight stone
Unreal's motion blur is always 'centered' (but we do give you the option to set a shutter timing now, which only affects when a sequence is sampled relative to the output frame)
We jitter the camera position but not the duration/time - the duration needs to be correct so that the motion blur makes a nice even gradient when built out of all of the individual subsamples
Just like a single sample would be
snow spire
fair point.... bias, i.e. controlling the fallof of the blur distance would be interesting to match (some) real camera shutters
tight stone
It wouldn't be too hard to add - would have to add an additional 'weight' when accumulating the results together, but it would cause a noticable step in your motion blur I think
tight stone
Right but say you have 3 samples and the outer ones have falloff, so they don't contribute as much to the final image (say 0.5, 1.0, 0.5)
I think there will be a noticeable stair step because the outer samples are only contributing half weight. It's admittedly not something I have tested
Since the motion blur for each sample is still 'centered', and you only get a nice smooth gradient if the values add up correctly
snow spire
probably not something I see myself needing anytime soon but I'll bet you a beer someone else asks for it π
tight stone
You can test it if you'd like pretty easy if you have something like Nuke. In the High Res setting there's an advanced dropdown for "write all samples to disk". Works without tiling.
Can render 1 or 2 frames with say, 3 TS and then multiply the first/last temporal sample by 0.5, add all 3 images together in Nuke, then divide by 2.
snow spire
I do have Nuke π
tight stone
I'd do the test here but uh, Nuke doesn't launch when connected via remote desktop 
snow spire
yes.... teamviewer or similar is your best bet for remote access of stuff like Nuke (open GL issue I think)
tight stone
This is the test we use, constant value keys that teleport the square between the reference squares
(Stepping through it in the editor so no motion blur)
Also be-warned that temporal subsampling will go outside your frame range on the first frame, since it needs to center the timing on the first frame, so need to make your data extend past your playback bounds
snow spire
thats pretty standard for moblur I'd say. we'd usually normally put handles on the shot or have out of range data
tight stone
This is what you get when using 3 temporal sub-samples, notice how the solid white section of the box is only 1/2 the original width, and then it falls off evenly on the outside edges
This matches the behavior of a single temporal sample using built in engine motion blur
(the 3 TS is just a little smoother in general b/c camera jitter)
snow spire
I dont think bias would step it.... would just fade off sooner, more like if I srgg curved that grad
maybe at small samples tho
tight stone
lemme send you the samples directly and we can test π
snow spire
sure
tight stone
I'm only convinced you'll get a step because of how much time I spent chasing down weird stepping issues due to motion blur that was the incorrect length
snow spire
ok, you sort of get some ghosting / stepping.... but you kind of get some of that in camera too
I think the ghosting I'm mostly getting is also becasue each image also has some TAA moblur too?
tight stone
TAA might exhibit some ghosting, usually only on the trailing edge
snow spire
I over engineered it a little and expression hooked up the multiply to autodivide by the correct amount
based on varying bias
tight stone
I do feel like 0.25 does show a shelf... I dunno what a real camera would do, but it's probably not noticable in motion π
snow spire
i'll see if I can try somestuff when I can get back in front of the build (maybe not till tomorrow now) I think dividing by more than 1/(number of samples) for bias might be prone to step
tight stone
I assume the stepping isn't an issue in real cameras since they're a continuous gathering of light?
snow spire
youd be surprised
at least with digital cameras these days becasue who knows
some still ahve mechanical shutter so I think that means they get arc distance stuff (effectively bias as we're talkign about
or I could be completely wrong about the whole thing
but I definitely notice ghosting moblur in footage on stuff I comp
tight stone
The idea of bias is definitely a thing that affects real cameras
snow spire
I'm not sure this tells us anything other than motion blur is weird and full of optical illusions
real camera mo blur from a thing
no idea what camera
tight stone
Yeah that's about my conclusion. Video games finally present a chance to have no weirdness (no motion blur) and then we go and fake it π
snow spire
is DOF different via this rendering too?
I'm getting differences in my test that look better but I'm unsure if my comparison is exact between versions
placid path
hi, not sure if this should go in #graphics but I'm having an issue with rendering out a final image using the sequencer.
I've rendered a few frames (with shot warmup/delay to let post processing quiet down), and yet my ambient occlusion disappears?
i even add a render pass for the engine to render out my AO and it just shows a white image.
in the editor however, visualizing the AO buffer and the distance field AO gives me what I'm expecting, and the viewport image looks much better
I'm using distance field AO with mesh distance fields enabled, and all of my lights are dynamic
what have i forgotten?
tight stone
@snow spire I guess technically it lets you see around corners (by a sub-pixel amount) and DoF is limited by not being able to see around things so... maybe?
tight stone
More than a subpixel if using temporal sampling, not sure if it's better or not though since our DoF isn't like how the real world works
supple garnet
Hello! I am having the issue where the materials of one of my characters disappear when I render the cinematic. It's visible in the viewport, only happens to one of the characters and when I am rendering it out. I also tried to place the same mesh somewhere else inside the level but it didn't work out - still no materials. Does anyone know a solution to this problem?
tight stone
Does it work in normal PIE?
snow spire
I've got a project where I need to control the timing of about 300 seperate objects appearing. Inputs I'll have is basically a datatable of each asset and a time when it appears. Wondering about simple ways to drive that. I can think of a couple inclusing doing it all within a blueprint, but curious if I can build a sequence from a datatable?
gusty heath
@snow spire Not necessarily related, but I built cinematics before based on plain text input, from XML. So I guess anything is possible π my cinematics were not sequencer specific, but spawning camera actors, etc. etc.
tight stone
You can construct sequences using Python, and probably read data tables too @snow spire - /Engine/Plugins/MovieScene/SequencerScripting/Content/Python has some examples π
snow spire
gee Matt... now you want me to learn Python too? jk I know enough to get into some trouble with it π
snow spire
well I kind of have a simple version working without any python. I make a blue print actor that in construction script adds all the correct static meshe components from a data table. I make a function that loops over all the components and if its appearance time is less than an input float then do x else do y. I call that input variable from the sequencer. function is a set<varname> function that <varname> is the float I'm using in the sequencer. function is set to call in editor and the float var is use in cinematics
tight stone
:shipit:
snow spire
set<varname> functions still blow my mind for how powerful they are for sequencer
...and I've never seen it mentioned anywhere before you confused me with it a few weeks back

Hey everyone, I'm trying to get a destructible mesh with physics on it from my level, recorded from gameplay and into sequencer. However when I record it, it only records the object in it's unbroken state. Is there something I'm missing, or do you have to set up the event in the sequencer?
jade cloak
hi everyone, I want to start playing around with mixed reality. has anyone tried doing this with a low budget kit (logitech webcam?)
gusty heath
@barren lagoon I think I've seen a comment a while back from LordNed to the effect that currently the recommended way is to render your audio in a third-party outside the sequencer. I may be wrong, but I vaguely recall something like that π
@green cloud If you don't mind me asking, what's your end goal? It's very simple to create camera actors managed by the player camera manager component and basically simulate a cinematic sequence, take a look at that video above with a test conversation.

green cloud
@gusty heath I'm working on some previz which will be an offline thing in the end, so I'll need to have it all recorded. I think I managed to solve all my problems in one way or another. Pretty hacky stuff from what I've gathered so far. For instance, my characters come out rotated 90 degrees after I've recorded them, switching Root Motion Root Lock to 'Zero' fixes this but that in turn cause other problems with components that do not get this offset applied.
So, has anyone come across recorded Characters that play with a rotation offset of 90 degrees? Is there a way to fix this without switching Root Motion Root Lock to 'Zero'?
ionic elbow
Any takers on recording a destructible to sequencer?
green cloud
@ionic elbow I haven't used destructibles but if it's a component class is this class set in the classes to record?
ionic elbow
Yeah the class is set to record, however the when the destructible is put int he sequencer it is keyed to spawned on and then when it is supposed to break it is then spawned off.
tight stone
@green cloud Are you using Sequence Recorder or Take Recorder
green cloud
@tight stone I just switched to the Take Recorder, thanks for the idea. This solves the 90 degree problem.. I'm still curious why it happens in the old recorder though.
Also I assume spawned particleSystems aren't working? I have to either have them as sub components inside a e.g character or wrap them in a blueprint for them to get picked up by 'Record Nearby Spawned Actors'?
Oh, the most important thing:
My character AI's animations are recorded in world space, so I have to switch on 'Force Root lock' on all recorded animations.
Is there a way to set this to be default for new animations, or record the character AI in local translation?
tight stone
@green cloud please bug report the particle system one. I don't think there is a way to change that, though you could add a relative transform track to sequencer which negates their starting position perhaps?
green cloud
@tight stone Will do, I have a list of things I'm going to report/ask for.. and I don't have a clue how to add a transform like that in the take recorder. I'm trying to get a setup that I can record, then immediately see the result in sequencer. Right now I'm almost there, it's just this 'Force Root Lock' that's missing
tight stone
I mean to the resulting sequencer track.
why do you need to see your animations relative to zero? Sequencer works in world-space by default as a general concept
green cloud
Maybe I'm doing something else wrong then.
I just add my AI and have all things as default, this records an animation that moves the root around - is that expected?
tight stone
Yes, iirc
green cloud
I thought animations should be recorded without the root baking any translations in, then the actor's translation is what's driving the recording as that is also recorded
So right now I have my root joint and the actor transform moving the character around, causing double translations.
And with the Take Recorder I no longer set 'Root Motion Root Lock' to 'Zero', I just set 'Force Root Lock' to ON.
With the Take Recorder Root Motion Root Lock doesn't seem to do anything when switching between Ref Pose and Zero btw.
tight stone
You shouldn't get double transforms, unless you're doing something unusual like moving both the actor itself, and moving the skeletal mesh component within it that the animation is playing back on.
There's a section in the Take Recorder that tries to extract the root motion from the animation and set it onto the transform track;
{
// We need to take the root motion data from the animation and override the data the Transform Track had originally captured
RootTransformRecorder->PostProcessAnimationData(FirstAnimationRecorder);
FirstAnimationRecorder->RemoveRootMotion();
}```
Make sure if you bug report that one to include a sample project with an AI in it.
novel sparrow
Greetings!
How to access that from a BP?
Is that a same as reference to Actor?
Cause it's not look like, and it's the only variable i've found.
green cloud
@tight stone Yea, that seems like it's perhaps for those times when you have an anim that's using EnableRootMotion.. my anims are purely played at origin then the actor is moved around by an AI controller. So you might think one could disable recording the transform track on the actor and only make do with the animation, as it's played in world space... but then there's an offset instead so it plays ok, but at an odd location.
Maybe it's something with the AI controller that's buggy
Or maybe my brain is buggy

Sequencer play rate track is just controlling global time dilation
But platform should use system clock to calculate Delta time instead of game clock which is affected by time dilation

Number two, I made the transform track of the camera additive, but alas the camera still did not change its position
soft thorn
@burnt tree for some reason you don't have a camera component with that cinecameractor. How did you spawn the CineCameraActor1?
burnt tree
@soft thorn by dragging it from the browser into the scene, as opposed to clicking on 'add camera' in the sequencer
soft thorn
Okay yeah so what you can do is hit "Track" -> "Camera Component" then hit "Track" -> "Transform"
Not sure why they are different but I see the same kind of behavior on my end
And then when you highlight the camera component you can edit the details on the right hand side under the Details tab
burnt tree
yeah it's weird bc in the course, he dragged the cam into the scene, and then selected the cam after creating the tracks, and all the variables were exposed
the reason I like this is bc I can manually put in the keys in the track, if I only had the settings un der the details tab, I won't have a visual on all the changes in the tracks themselves
soft thorn
Yeah I'm not sure why they changed it in 4.24 since you can click the add camera button within sequencer and get the result which is covered in your screen shot
burnt tree
the lower screenshot is 4.22, which is after he dragged the cam into the scene, not by adding cam in seq π
that's the difference
I can't replicate the step in 4.24
So for anybody reading this and maybe confused, let me try to explain it in short:
The first picture is a screenshot from my seq in 4.24.2;
The second is from the course video which was with 4.22;
I followed the steps exactly as instructed, yet get a different result.
soft thorn
I would probably read the patch notes then to see what changed

is there a way to run a subscene in reverse?

Is it possible to animate spline points in sequencer?
tight stone
@burnt tree You can just click the + button on the right side of the CineCameraActor1 and add the tracks. Some are on the actor itself, and some are on the Camera Component (as you can see in your second screenshot). You can set any filmback size you want, the presets just set the Width/Height field so you can just type in any number you want.
@rose pine I don't know if negative playback speeds work, you could try it, for the sub-section
I forget if take recorder automatically adds a camera cut track or not. https://docs.unrealengine.com/en-US/Engine/Sequencer/Overview/#hierarchicalbias
It could be that it does and that the shots are taking precedent over the master track due to evaluation hierarchy
you can probably just go into the shots right click on the camera cuts track and deactivate it
click the lock in the top right π
(It's designed to prevent you from accidentally manipulating your recorded data when previewing/playing it back during a live recording session)
rose pine
yea no luck with -1 playback speed, guess ill just make another sequence of it going in reverse and just play that
is there a way to have audio trigger when sequences play in reverse? like in matinee?
soft thorn
So can you animate a camera within sequencer and also have its transform animation be in relation to the player?

hi. I have two problem when i try to render cinematic. First one, after render cinematic i dont here audio tracks. Second one, some emitter of rain storm dont visible in cinematic. But when i play cinematic in ue4, all work fine. How to resolve this problem or what guide i should read to fix that. my ue4 version is 4.18.3. I use emmiters from this assets pack https://www.unrealengine.com/marketplace/en-US/product/soul-city/

@upper gale audio doesn't really work properly when exporting as far as I know. Try adding your particle emitters to sequencer and setting them to start emitting

@rose pine I dont have 4.21 but you can attach pretty much any sequencer item to another. drag your soundcue into the sequencer, click on the track + button for the cue and choose attach then pick an actor to attach to. if you need it attached to a skeletal mesh you'll probably need to attach it to a socket in the skeleton
I tested in 4.22.3

In 4.21, can sequencer events receive inputs or is that added in later versions?

Hi guys, is there any way to carry materials across from Houdini I to unreal using an alembic cache? We have a destruction cinematic using Houdini and so I've assigned a string attribute with the reference to the material in Unreal, but when I bring it in the cache it doesn't link up automatically, alembic would be our preferred format so if there is any way to do this it would be great to know

@upper gale does your rain particle system only exist around your player character? if so then it probably wont be around your cinecameras in your sequence unless its near the player character.
mint monolith
@upper gale Could be what @snow spire is saying. I have used Soul City before without issue. It might be culling particle systems far away from your player character. Try deleting all extra character shit for now and seeing if you can get it working properly in just sequencer
quasi trail
hey guys I use this parent setup of objects to animate them quickly trough the sequencer but everytime unreal saves the level the parenting is gone, also when i render out my sequence they got also detached
mint monolith
@quasi trail that little lightning bolt symbol means that the object gets created at the start of the sequence. So having something created parented to something always there parented to something created can cause issues. Use the attach track inside sequencer and maybe make them all always there by turning off spawnable.
quasi trail
thank u π I also found out that i can attatch the objects directly in the sequence

Is it possible to blend from a sequencer camera to player camera?
tight stone
Not in the current version. For now omit camera cut track and use event track to call SetViewTargetWithBlend to have it blend into the camera animated by seq. Camera cut track will do a hardcut to specified camera so need to avoid that

This page shows that UE4 has some video recording capability, however it's in the context of sequenced scenes.
Is it possible to use that functionality, especially including the fixed framerate playback, for outputting videos of replays? Assume we've already got replay recording and playback sorted using the engine's standard replay system...
tight stone
You'll need to build your own system and reuse or use similar techniques. Maybe you can just generate an empty sequence which is the same length as the replay and start the replay as soon as movie rendering PIE loads

fiery prism
is there anyway to update an actor based on sequencer timeline while in edit mode? I have an obj sequence that I am trying to animate cameras around but I am shooting blind right now
snow spire
@fiery prism do you mean an like a blueprint actor that only updates during game? depending on how you're changing that there mght be a couple of ways to see that in the sequence while scrubbing, otherwise a bunch of other things can turn up if you use simulate in the viewport.
fiery prism
yeah, its its own file format but its similar to and alembic file. Being able to see it while scrubbing is the best way to put what I meant thank you. I think doing it during sim would work for virtual production type hand camera stuff for sure and is kind of my backup plan right now
snow spire
@fiery prism without knowing exactly how your file format calls it's frame update it might be a bit hard for me to guess but.... you can expose a variable in a blueprint actor and animate the value of that variable in the sequencer timeline to cause a frame change.
there's a couple of tricks to make that work tho.
first trick is we need to tell the blueprint to do something everytime that vlaue changes rather than constantly doing that on event tick or somesuch
happily there's a very useful thing that @tight stone told me a few weeks back.
if you have a variable in your actor if you name a function set<yourvariablename> (i.e. variable MyFloat would have a function setMyFloat) then everytime that variable MyFloat is changed even from outside (i.e. the sequencer) then that function is called
this means inside setMyFloat we can execute the update logic to cause the obj frame update.
the setMyFloat function needs and input that matches the type of MyFloat variable AND to get it to work in sequencer checkexpose to cinmatics on teh variable AND call in editor on the function
fiery prism
ah thats awesome thank you so much that should definitely work
snow spire
it is the coolest thing and it saved my bacon bigtime a few weeks back when I got my head around it.
it took me a bit to do it right but hopefully I've explained it well enough
fiery prism
ill let you know how it goes
snow spire
jsut make sure inside your function you use the piped in input value to drive the logic
fiery prism
@snow spire worked great thank you! have you figured out a way to associate the number with the timeline? I have it going but always advancing
fiery prism
ah I figured it out animate the value in the timeline I get it now

Hello folks, I have question regarding Sequencer. Is sequencer capable of changing states such as shots or any other variables at runtime? Not editor time. I'm thinking more about something like procedural weather system where the entire day would be one timeline and each shot would be weather type (rain, sunny day etc...) For each day, the master sequence would "shuffle" sub shots for morning, day, afternoon, night with predefined shots for weather.
Here what I mean
Or is it better to use Timelines instead?
Each shot (or preset in this way) would drive everything necessary in the world (particels, wind, sun position, materials (cloud density, speed etc.)
When the sequence reach end of the timeline, it will randomly shuffle weather for next day.
My question is if the Sequencer would be capable of maintaining this (at runtime).
tight stone
You could build your own system that chooses level sequences to play and then listens for the on playback finished event to make your decision about the next segment
mint monolith
I'm using Additive transform sections to adjust baked (keys every frame) animations. Is there a toggle to allow me to edit transforms in the viewport so that it will affect the additive section and not the standard section? At the moment I am resorting to sliding numbers in sequencer which is not ideal.
tight stone
@mint monolith can you right click on a section or track and see if there's something about key this section? not sure it'll solve the problem here though
amber igloo
You'll need to build your own system and reuse or use similar techniques. Maybe you can just generate an empty sequence which is the same length as the replay and start the replay as soon as movie rendering PIE loads
@tight stone Was thinking along those lines, but when rendering the movie it starts the game with no server at all, so none of the recorded replay data gets played back... Tricky
tight stone
If you're compiling from source you could try modifying movie rendering startup... it's just making a PIE session, not sure how to view replays in PIE

Hey folks. I'm trying to render out a sequence with a Composure element, but it always crashes the editor as soon as I hit Capture Movie. The crash error is:
Assertion failed: Inputs.bDumpToFile || Inputs.bOverview [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Renderer/Private/PostProcess/PostProcessVisualizeBuffer.cpp] [Line: 335]
The sequence otherwise renders perfectly fine; as soon as a Composure element is involved, I get this crash no matter the configuration. Any leads would be greatly appreciated.
brazen geode
Worth noting the project is made with 4.24, especially now that I've discovered the problem doesn't exist in 4.22. I made a test case with a similar project in 4.22 and it exported without issues, so this may be a bug introduced in 4.23 or 4.24. π¦
tight stone
@brazen geode Hmmn, I think i fixed an unrelated thing that tripped the same ensure, if you @ me in 12hrs I can look, was a pretty simple add-another-bool-to-an-if-statement kinda fix. Only works if you're building from source though
brazen geode
@tight stone Working with a binary build unfortunately, but we were able to use an alternate method to render out the passes we needed thankfully. Still very curious to know if you have a lead on the cause for the crash, though! Not much to go on with that error, especially since AnswerHub is down. π
tight stone
@brazen geode Looks like in November I changed it to say;
brazen geode
That certainly matches the error output we got. Any idea what causes that or why it's only happening when we try to render out a sequence with Composure Export?
Oh wait, are those red lines what it used to be? π€
tight stone
Red lines are modified lines (with what it's been turned into)
The error I fixed was admittedly gbuffer passes and not composure
brazen geode
Ah, OK. Hm... I may file a bug report then. The crash has a 100% repro rate in 4.24.
Thanks for responding! Appreciate it.
mint monolith
@tight stone That didn't seem to work, even when locking the base transform section. I assume because when you move something in the viewport those numbers dont actually change. Is there a better way to layer on transform animation? Sliding xyz locations and rotations is really arduous for character stuff
tight stone
Do you have autokey on
brazen geode
Does Sequencer support working with layers at all?
tight stone
@mint monolith \o/ yeah if you don't hit S to key the transform or enable auto-key then changes in the viewport are made the next time you evaluate the sequence (ie: scrub/play)
@brazen geode NMI
brazen geode
NMI?
Need more info?
I'm referring to Layers, the ones that have their own panel in Unreal and you can add actors to them, hide them, etc.
brazen geode
I don't think so. I mean... OK, so I know Sequencer has Level Visibility tracks for toggling visibility of levels in a sequence.
I was wondering if it supported Layers in any similar way.
I didn't see a Layer Visibility track and I couldn't drag a layer into the sequence, so I poked around the docs, didn't see anything, and figured I'd ask here. π
mint monolith
So you are trying to hide all objects in a group?
I think you could use subscenes or something that way
brazen geode
Yeah, exploring a few different options at the moment.
mint monolith
In the past when i've wanted to hide shit i've added a visibility track, pasted it into everything and then whenever i need to change it I select them all and key them. Pretty messy but an alright quick fix
brazen geode
Yeah I've used visibility tracks in the past with other clients as well. It works alright as an alternative to comp layers.
We're having a painful experience with Composure, so I'm revisiting old methods for rendering out "layers" from Sequencer without it.
mint monolith
Ah right. Havent attempted it in a while but have you tried render layers through .exrs?
You could maybe make a script that runs through and renders objects by ID's in seperate sequences
mint monolith
Yeah
Won't render them seperately
but you can assign ID's or use depth maps etc. which can be just as useful in some instances
Hey Matt when I copy paste my additive transform section it brings the base section with it. Any ideas on creating an additive section with key this section on 200+ objects. Is Python the way to go?
brazen geode
Hadn't considered them because we're rendering out foreground, background, etc. that kind of layers. Figured it was either Composure or level visibility tracks.
mint monolith
Depends on what you need to do in the compositing stage really
tight stone
No great solution. You could write a track that edits the layers property (it's just an array of strings on the actor) but we don't have generic array support
No good way to choose which ones are visible right now though either

Hi everyone, I'm having some strange render issues with deffered decals. I have a camera slowly pulling back through a damaged hole in a wall, there is a decal on the inside left and inside right that get revealed as the camera moves backwards through the scene. For some strange reason the decal on the left fades in as the camera moves back, while the decal on the left slowly fades out and disappears. I cant figure out why this might be happening, is there a setting I am missing? this doesn't happen with any other decal anywhere else in the level. anyone have any idea whats wrong?
I should also add that this only happens at render time, when flying around the scene or scrubbing in the sequencer it doesn't happen... weird
gloomy garnet
@gusty heath - I had the similar issue I posted over on the RT-VFX_Unreal board. Does the decal have proper alphas in the file? I know decals are quite skittish when cam zooms out and decal has geo in close proximity. Try changing it to a Surface in Blend Mode. Use Default lit and changed Lighting Mode to Surface Translucency Volume. See if that helps. . . Also, when outputting, I check off, the 'Render after DOF'. It's down lower in the material settings. so if there's any atmosphere in scene, it keeps it at proper depth. . . .
Even after doing these changes, i had to save, reopen UE4 andkeep testing till it output correctly.

Anyone know how to animate material inside Sequencer? or transition from 1 material to another?
I have emissive material that I want to turn on and off, basically a flashbulb animation
tight stone
You should be able to just expose the scalar value as a parameter and then add a track to your static/skeletal mesh component for that material
Element 0 will let you animate exposed parameters on the material, while Material Switcher lets you animate which material is assigned.
warm pelican
sorry Im couldn't understand anything you said I'm kind of new to ue4. Where am I supposed to go from here? I added my static mesh which is this lightbulb to the track
It has just emissive material

Click +Track on the highlighted thing in Sequencer @warm pelican
And add the Static Mesh Component, then click +Track on the newly added one

Awesome, everything works I tried animating from 1 material to another
have found another alternative but this way is easier definitely
but also this is probably not realistic on how to set up flashbulb I guess

Hi, I was hoping to get some help with some video playback issues I've been having. I am working on a VR project for the Oculus Quest and Go where the player is in an elevator with some videos playing. When I watch the video in PIE on the elevator screens, it looks crisp and plays a smooth framerate. The screens are on all 3 sides of the elevator (one mesh, 1 texture), and the user is inside the elevator very close to the screens.
However in either headset, playback is much more choppy, and I often see banding issues that don't appear in the PIE version either. I have seen videos play in both devices at a relatively high quality, and was wondering if there is either some settings in engine that I am missing, or if I have to encode the video in a very specific way for this type of playback.
Attached is all the settings I could think to take a picture of. If you need to see anything else i would be happy to take a screenshot of it. Thank you in advance

There's way less performance available on mobile, decoding a 4k x 2k video at 30fps (in HDR to boot) is a huuge ask of a mobile device.
Try encoding both the video and audio to something that has a native hardware decoder on the device (and that is supported by Unreal, I don't know what codec this is off the top of my head) to ensure you're at least getting hardware accelerated decoding. Note that there's often size limitations on the hardware decoder, probably closer to 1080p than 4k x 2k though...

If you put your skeletal mesh in the world and click on the dropdown for the animation blueprint there, does it show up?

If you scrub into the sequence to where the Skeletal Mesh track is evaluated, do your options change?

You'll have better luck posting the information where everyone can see it so that if someone else has an idea they can chime in.
Also more information like whether or not you're using raytracing, if turning on or off screen-space effects makes a difference, etc.

@remote rapids if it's only facial animation then turn Additive Anim type to local on the animation asset

Hey All. . . So I'm using UE4 raytracing in a few cinematics. It's a room and I'm using rectangle lights in my scene for the key lights. Once I set the rectangle lights up and build them, my scene turns extra dark. I have to over crank the light intensity, but doesn't seem to brighten correctly. Has anyone had any issues with raytracing rectangle lights? Thx ahead of time. . .
mint monolith
@gloomy garnet Make sure exposure is locked. Can you post a picture of what it looks like when it doesnt brighten correctly?
gloomy garnet
Ok. . . I've locked it down per camera. That's under control. What I'm running into is how dark it gets after the build . I have been increasing the bounce & per pixel settings in the camera as well. . . It have increase the output time per frame, but its getting better. . . .It seems that the higher quality ya have in your level, it' get very expensive.
mint monolith
Sounds like something is fundamentally broken in your scene
gloomy garnet
Quite possibly. . . I thought Raytrace would bring more to the scene. It can, it does. . but , the effort is more than the result. Might as well render it. Besides, I get preatty much a good result w/o raytracing & build. .. .
rapid elbow
Hello there, I am looking for anyone who can give immediate help as I am running into a frustrating issue using the level cinematics as EVERY time I render a movie it seems to choose some random default camera despite putting in the right camera in the camera cuts...
mint monolith
@gloomy garnet The benefits Ray tracing offers are mostly on the realtime side. You dont have to build anything to get it looking good. Building lighting is largely unrelated to the newer ray tracing features
@rapid elbow It should only override based on the camera track. If you have a sequence with shots inside it make sure that there aren't conflicting camera tracks or that your shots don't overlap
gloomy garnet
@mint monolith - Yes. Thank you. . I'm finding that out the hard way. . . . Not a lot of current tut's on this yet.
gloomy garnet
Ahh, Cool. Thx!

OK, I have got my main camera rendering properly, but now I still need help setting up camera cuts properly....
At this point I am frustrated enough that I feel like I should just make a totally new duplicate scene and remove the cameras from the outliner....

Right....like one thing I noticed is in the shots he has mutliple shots on top of each other in one shot slot where as when I use 4.23.1, I only get one slot per shot..

If you drag the shot section down it should pop onto a second row. Only one shot section will be evaluated in the event they are overlapping though.

Hello All. . .So, I'm doing cinematics with Unreal Raytrace. Do I need a Post Process Volume, if i'm setting all my Raytrace parameters in each Camera? My UE4 keeps crashing. Or, is that just what Unreal does when having animated Cameras using raytrace?
tight stone
The results of Cine Camera and Post Processing volumes are blended together to produce the final results, it doesn't matter where you set them.
You may be experiencing out of memory crashes or Windows TDR crashes, the latter of which you can fix, the former not so much.
gloomy garnet
@tight stone - Thanks for the info. Pretty sure it's the former as your said. Think I need a 2080 graphics, no less. Not sure I'm savvy enough for the Win. TDR issue. Cheers
tight stone
@gloomy garnet The TDR is pretty easy to work around, there's guides on the web (Windows Timeout Device Recovery). Just need to edit one registry key to put in a higher value
I believe the windows default is 2 seconds, so if any call to the GPU takes more than 2s it thinks the device has crashed and kills it. You can increase that to 30-60 potentially, but if your GPU does actually hang then you'll have to wait that whole time while windows is completely non responsive
(So maybe don't just set it to a value like 600 π )
gloomy garnet
Lol, . . .Right. Didn't realize the timeout is that short. If I can get it to 20sec. that would help lots. . . Thanks 4-da knowledge. π π
tight stone
Unfortunately I don't think it's very obvious which kind of crash it is. You can try looking in the engine logs (MyProject/Saved/Logs/...) afterwards but I'm not sure the software knows either. You can keep an eye on Task Manager's GPU tab and look at the memory consumption tooo

Hi, just started messing around in sequencer - I notice small pops on animation clip transitions, what is the best way to prevent these?
tight stone
@north arch Put the clips on the same row and overlap them so they cross-fade.
I think it's resetting motion vectors between the two sections so you get one frame of motion blur doing the wrong thing.

Aha, thanks! The UI is kinda finicky but I was able to blend out those pops.

gusty heath
@tight stone I apologize for tagging, but recently I was playing with a proof of concept inspired by the mandalorian TV show use of unreal engine. I put together an example of a cutscene created on the fly at runtime from external data, and I wanted to share the results. Here is the example https://youtu.be/X_DPGSqqIJo
it's basically using unreal engine for the Paragon characters rendering on a green screen and the end result dumped in Adobe After Effects, in this particular test I'm using some Star Wars background. I implemented some basic head tracking too.
I'm not using sequencer, the external data creates the actors and the cameras and makes the layout of the scene, etc. The external data can come from anywhere in any serialized form, in my example it comes from an older Bioware videogame

In my sequence apears a "Plane" who's not really here. I checked the outline twice.. D:

@muted hedge Build it around a Spawnable and then use dynamic runtime rebinding to change the binding to apply to your particular instance instead of the spawnable.
@gray sparrow Does it show up in PIE?
muted hedge
@tight stone oh wow I would have never guessed that. I'll look into, thanks
gray sparrow
@tight stone "PIE" in meaning of, play in editor? Yes. Thats in play-mode π

Try simulate instead (or eject out of your pawn during PIE) and see if you can click on it and see where it is in the World Outliner @gray sparrow

Yeah I think those are all set to always loaded, though they also look kind of busted. Did someone move files around or rename maps maybe?

Hi All. I'm having an Issue with the Preview Shader Indicator showing up in my Render Movie. . . . I have a series of separate sequencer shots in UE 4.24 using Rayrtrace. Each shot is using the same Level and 8 props, a table with some weapons. After a week of tests, I found the right lighting. They consist of mostly point lights, 2 spots and 2 rectangle. All lights are in the 'Blue- Green' in the 'Light Complexity' & 'Stationary Light Overlap'. In the last couple weeks, the preview never showed up in my avi's until a day ago, when I started refining the Camera raytrace setting per shot. Is there a wat to Turn Off the 'Preview Shader Indicator' in my AVI's manually??
tight stone
You probably need to run Build and bake lighting on all the levels and save them
gloomy garnet
@tight stone - π€ . . .I thought the same. So, I duplicated the Level, and ran a build, with raytrace on , and baked the lights. This would make the whole environment Level become so dark, and would sizzle. FYI, All my background lights were static, except for the 2 'stationary' point lights that interacted with my characters.
tight stone
I believe the Preview warning shows up after you have moved objects that are marked as static (or maybe it's lights that have been marked as static and moved?) and it's switched them to a realtime shadow
@gloomy garnet Try going to the World Settings and checking 'Force No Precomputed Lighting'. It'll switch them all to realtime lights but maybe works in your case?
gloomy garnet
@tight stone - Watched the UE4 tutorial and Live interviews going over the raytrace abilities. They said their environments in their test were hybrids. Both baked lighting and raytrace. . .But Never went into their set up. Mainly they were just selling the 'Raytrace' thing.
@tight stone - Ok, I'll check into the World Setting. . . Thank You
tight stone
They should be hybrid just fine, just trying to think of a workaround to get you going until you can figure out why the lighting build isn't playing nice.
gloomy garnet
@tight stone - I was thinking maybe by Hybrid, they mean: Build the lighting without Raytrace. Then reopen level in Raytrace with the Non-RT build, and only adjust the stationary/movable lighting. As far as props, now that I think of it, they were movable before. I changed them to static (since they don't move in shots) to save render output time. . . .
tight stone
I suspect that ray tracing only affects dynamic lights that cast shadows.
gloomy garnet
I know one thing. . . You are WAY better off with the Highest 20 series graphics card you can find!!!
tight stone
Static lights get vs. Static objects get baked down, but for movable objects they need dynamic shadows cast.
If your light is movable I think it casts a dynamic shadow (which would be affected by raytracing?), or if your object is movable it casts a dynamic shadow - I think.
Once you move them to static they're going to use lightmass and become static shadows stored in textures.
gloomy garnet
Even with Drivers, the 10 series(1060 -1080 graphics cards) won't give you accurate setting out puts or crash when you begin to set high parameters to the raytrace settings. . .
@tight stone . . . I think Your comment of 'objects to static', might be the issue. . . Thank ya lots for talking me through the issue-! It was a real big help to get me to the next step to a solution. . . π€ π

hybrid pelican
ya but its a hard problem to solve
theres a new plugin that Unreal has but I cannot find any docs on sphereical captures - if u look in the plugins you can find it - maybe they are coming out with something I dont know
tight stone
@clever roost No. You can build UI animations inside of UMG using the Timeline tool (which is another instance of the Sequencer editor), but from the main Level Sequence editor you cannot animate nor spawn UI elements. If you need simple visibility or events you could make a blueprint actor which 'owns' the widget (and creates it) and animate properties on it.

@pallid spire I believe it's built using Matinee, Sequencer's pre-cursor. Attempting to open the asset should ask you if you want to automatically convert it to a Level Sequence which will preserve most but not all Matinee content.
pallid spire
I opened the project but didn't see anything like that
I can press play and it plays the cinematic

@pallid spire If you find the Matinee actor in the level and try to open it for editing is when it shows up I believe.

Hi all, hope everyone is well and healthy during these strange times, I was wondering if anyone has ever managed to create an atmosphere pass in unreal engine for use in a compositing package such as Nuke? My thought was to create a post process that turns everything black and render with the atmosphere but this doesn't seem to be working. Does anyone have any thoughts on this?
tight stone
@cursive parrot Why not have one client in PIE, the other a separate process launched with -game, and the server? That way you can record using the PIE instance, Take Recorder (and Sequence Recorder) work in PIE
cursive parrot
@tight stone - thanks Matt. So I did try with both windows in PIE, and at most could only record one. I think my issue is that for the player, they are unable to see themselves in-game and can only see their opponent. I could temporarily turn off hiding yourself just for the sake of recording though. Let me try that after work.
tight stone
@cursive parrot Ah, sorry I was thinking of like a third person game. Can you add a third person, a spectator and he's the one who records? And then two clients run in -game and the server?
I'm not totally sure how you're going to play as two people at once but I leave that one up to you
normal fable
If you want to capture every moving actor in your game as data that can be played back later (To then set up shots in sequencer), is Sequence Recorder best for this or should I be using the replay system to capture the gameplay?
I have been trying with the sequence recorder but most actors are invisible, aren't playing the correct animations (it looks like they are frozen on the last frame of the custom saved animation but re-applying it and scrubbing does nothing)
They move correctly but since they are invisible and out of position it breaks the intention

Hey guys, have a question I also asked in the level design chat, but relates more to cinematics (I think?). I am loading different cinematics together and levels and notice that my exposure gets overblown for the media plate and not the CG actors. I am using composure if thats helpful info.
mint monolith
@gusty heath Add an event track
fresh saddle
@broken snow I haven't used composure, but if you're loading new levels and they have newly streamed Post Processing volumes overlapping the current ones, if you've checked the exposure option for one and not the other, the one that is checked is going to override the default value. I just make sure everything is checked on my PPVs to avoid this, also Check the priority values of your PPVs

Is there a way to turn off safe zone markings when rendering out a cinematic? They are showing up in exported video capture.

@fresh saddle I am using the same PPV, but I am going to see if I change the priority values if that helps. So odd that it would be a factor if it's being unloaded.
seems to still be occurring. Such an odd thing >.> I am going to try putting the PPV into the persistent level and see if that resolves it.

is there a simple way to keep camera from flipping 360 all the time?
to go from 350 to 10 it flips and takes the long turn

@cursive parrot You'll need to figure out how to turn it off for normal PIE unfortunately.
@storm stream You can use the "Game Mode Override" option in the settings to point to a different game mode (or launch the engine with -noloadingscreen(s? I don't remember which), but it entirely depends on how your game is set up to do a loading s creen.
@errant estuary You'll need to enable quaternion interpolation for that transform track which will take the shortest path between angles

was having a play with mesh distance fields but the resolution is too low, and i have too much geometry in the level it woukld be a huge perfomance hit
i thought about lightmass too, but as my light is mostly coming from the emissive screen plane it's wouldnt work
so i was thinking to just bake some nice shadows so that they show up when then screen is lit
otherwise, the space is mostly black when the screen is black

how to remove visibility hdri background in render sequence?
tight stone
@copper escarp extend your camera cut track, it tells the sequence what camera to use for a given frame, otherwise it defaults to the players view which will be at 0,0,0. Is your hdri background an object in the scene? Can you drag it into Sequencer from the World Outliner and animate the Visibility track?

@tight stone The first question is solved, thank you!
Visibility track doesn't work, hdri disappears and doesn't affect on world(

I think you're asking a different question than you asked, and I don't think there is a good solution for you right now.
I believe they want the influence of the HDRI for lighting but to remove the pixels from the background from the final image.

Ah in that case I got around this problem earlier by making a massive plane, black emissive material, set to not cast shadows and attach it to the camera at a distance between the HDRI and everything else in your scene

when i want to move the timeline i have to click left of where the marker actually is

also, when i attach multiple objects to my motion controller it works fine outside sequencer, also inside sequencer when its on stop but when playing or scrub enabled it moves all the objects to some distant location, still attached to the controller tho(this is not shown in the vid)
first 3 problems do not accur in sequencer outside the VR editor, the 4th i wouldnt know cuz no motion controller in normal viewport and never tried any of this

What's the best way to add a hundred actors into sequencer with the same animation?

Looking for a (paid) tutor to learn workflows from asset creation in C4D to rendering in Unreal. If anyone's interested please PM me. Thanks.
tight stone
@pallid spire scripting probably. Check the Sequencer Scripting plug-in, and the python examples in the folder
pallid spire
Does anybody know why it's all grainy? If I pause during the sequencer it's not grainy, only while it's playing. The render is the same.
I tried all the AA settings but nothing changed
pallid spire
I fixed it by just removing one of the extra cinecameras that I had, don't know how it caused that issue.

I have a boss that activates through a variable. How do I activate the variable during the cinematic so the boss moves?
tidal hedge
Is it possible to blur both the near AND far focal areas with a CineCamera? I could have sworn I saw a UE4 video recently where this was demonstrated, but I can't figure out how.
tight stone
@stone igloo Add the boss to the Sequencer, add an Event Track and call the function.
@tidal hedge I thought it just worked based on physics - pick an aperture with an appropriately sized area in focus and then set the focal distance as needed.
https://youtu.be/jbD9YnWFxnM?t=22
ie: I think here the table leg/far right chair is out of focus and so is the background. From the ArchViz learning sample

@tight stone How exactly do event tracks work? Do you mind explaining it to me or pointing me to the right direction?
gentle hamlet
Hello, I dont know if this is the correct place for this issue, but my ue4 crashes everytime I try to play the game with the level sequencer running. I have a video to show this:
errant estuary
delete it?
gentle hamlet
yes, but how would I play the animation?
gentle hamlet
yes I did and it does the same thing
errant estuary
and in PIE?
gentle hamlet
in PIE, it also crashes
errant estuary
its also crashes the editor?
gentle hamlet
yes
errant estuary
i never seen this, anims allways for for me from seq, also in packaged
gentle hamlet
I'll try to put it in the blueprint to see that will work
errant estuary
use just a skel mesh in seq and replace with bp in the end?
try running it with just a skel mesh with the anim playing
errant estuary
np, now u either work around or try to do a proper fix π
cuz that bp shouldnt crash the editor π
gentle hamlet
I've just put a work around in, as I have the bp there but it is 'hidden in game' so I've set so it will show after the cut scene is done
but it is very werid
errant estuary
maY something on construction script
its all smoke and mirrors so hiding stuff wil work just fine π
there is something happening in that bp when the anim starts playing or something it would bug the crap out of me π
it allready does and its not my BP π

pallid spire
Is it possible to have several sequencer tabs open?
errant estuary
that would cause a callstack?
tight stone
@stone igloo When you create an event track in Sequencer and make a key, that key calls a function in the Sequence Director, which is a blueprint contained inside of your specific level sequence. If the event track is a 'Master Track' (isn't a track on an Actor but instead at the root level) then no arguments are passed by default to the function when called. If the event is on an actor, when the function is created it has that has that argument as a parameter, and will pass the particular instance to the function. If you add additional function parameters to the created functions, then they will show up as the Payload argument in the key properties.
@pallid spire No

hey i am getting problem at rendering my particles arent visible on my render
some of the particles are visible but some aren't visible any know how to fix it
warmup was given about 1000

Do they work in PIE? Possibly a visibility culling issue.

Hello, why doesnt my level sequence show/work?
gusty heath
Hi guys, I'm creating a sequence in which I need to use a blueprint actor but it seems like it doesn't work. I tried to use a custom event like on this tutorial but it doesn't work : https://docs.unrealengine.com/en-US/Engine/Sequencer/HowTo/TracksEvent/index.html
I don't see the problem, seems like the trigger doesn't start so idk what happen.
tight stone
@gusty heath Events won't be called when scrubbing in the editor unless you have the "Call in Editor" checkbox ticked in the event key properties. That being said, I don't think that will work, Blueprints are not really 'running' so I don't think the Timeline will work. You would be better off applying the animation to the skeletal mesh directly in sequencer, or building the animation itself in Sequencer if it is simple. If you need to change what object it is animating at runtime you can use Actor Binding to swap out which instance the tracks are evaluated on;
https://docs.unrealengine.com/en-US/Engine/Sequencer/HowTo/AnimateDynamicObjects/index.html
gusty heath
thanks for your help Matt, I think I will "deconstruct" the blueprint nodes in the sequencer like this : add animation, modify the dynamic material directly in the sequencer's timeline and that's it !

Some Of The Particles Aren't Visible Anyone Please Help Me
kindred mesa
@little reef Have you checked the LOD settings on the particle actors?
little reef
Yea changed To High Details Still The Same
tight stone
Try r.ParticleLODBias -10 @little reef
When you're in game LODs take effect (which can still be done even on high settings, especially with game optimized particles from the store) so that console command will tell the engine to take ten steps higher quality LOD for any given calculation (which may be based on screen size) if possible, which should be more LODs than any particle has
Also if you end up being unsatisfied with how the grass looks in motion you can try downloading the Release 4.25 preview and trying the new movie rendering which lets you do real anti-aliasing samples instead of TAA (which is what causes iffy looking grass usually)
little reef
let me try and see
little reef
still the same after "r.ParticleLODBias -10"
@tight stone Any one please help me to fix the render
only some particles are visible
tight stone
At this point you're going to have to experiment. Movie renders use PIE so if you can figure out why it doesn't work in Play in Editor you can fix it. Experiment. Move the camera around. Examine the behavior. Does it not start immediately, does it disappear when you're too far, does it disappear if you look too far away, etc.
barren lagoon
hello! how can i make sure that a camera is at a perfect 180 to another object in the scene?
in the Z direction while having rotation selected i mean
never mind, just parented it to the object haha
pallid spire
Did they ever announce the winners of the film jam contest?

I would go into the particle emitters and look at their settings, or look at the actor and see if there are min/max distances specified somewhere.

Sequence Display Rate doesn't seem to work, no matter what I choose it still plays at a high fps
barren lagoon
how do i extend out the range here?
the left one
once i hit the 5 second mark the camera cut just stops doing what it was doing
these are my sequence recorder settings
barren lagoon
okay, this is weird
i'm not sure what i did
but now it's extended out to here
π
tight stone
@pallid spire Display Rate really only controls how far apart the keys are, time is still calculated in seconds so it doesn't matter if you have a 2fps or 90fps sequence, half a second is still half a second. If you want to play it in say 2fps there isn't a built in way to do that right now without also setting t.maxfps=2, which probably isn't good for the rest of your game.
tight stone
@barren lagoon that is a combination of both inner play range and outer section range + offset
barren lagoon
aha, got it
yeah like i said i just had to extend my shot out lol
i was just focused on the camera cut track
i'm very new to Sequencer but it's so much fun
especially since i'm using it in Squad's SDK
i'm getting a little confused by the inception going on in my sequence. if i want to trim the length of my shot, do i adjust the shot or the camera cut?
i'm going to assume shot
tight stone
The camera cut only tells the sequence which camera to evaluate for a given time, it's not even a required track
The shot controls which sub-sequence is being evaluated at all
barren lagoon
that makes a bit more sense. say that i want to cut out a few seconds from the start of my shot. what do i do then? dragging to the point where i want it to start doesn't seem to work.
tight stone
You can just drag the left handle of the shot section in the parent sequence. Or right click on the properties and choose a start offset
barren lagoon
haha you legend. thanks so much! i'll report back if i run into anything else π
barren lagoon
alright, so my shot is trimmed just the way i like it. however, when i bring it over to the start of my sequence, it restores the shot instead of keeping it the way i like.
not sure what's causing that
so i basically have to keep it at the 2.58 second mark otherwise the trim is erased
high locust
Will a vignette simulate tunnel vision well enough, or should I screw with the FOV as well?
barren lagoon
i have this shot trimmed out exactly how i want
it starts and ends at the spots i want it to
when i drag the shot back over to 0.00s, it goes right back to the very beginning of the shot
as if i never trimmed it out
i'm not sure what's causing this
barren lagoon
never mind, i know exactly what it is

hybrid ore
hello, im trying to find a workflow for my sequence recording, i have 1 dog and 1 kid and i control them as pawns so first i record the kid running around (while controlling it) and then record the dog following him , so in the dog recording i simultaneously play the kid recording so i can know where the kid is , and at the end i want to use the 2 recordings and mix them to have the kid and the dog in one recording , is there a better way ?
mint monolith
@hybrid ore Checkout take recorder, I think it might have this functionality built in
sweet hawk
Okay, I need a help with this issue.
I have forced Engine to NOT use any lods, but when I render a shot It uses LOD.
and turns off emissive for some reason....
mint monolith
@sweet hawk How did you force it off? Console overrides don't carry over when capturing so you will need to execute them on begin play in the level blueprint
sweet hawk
Ohhhhh! I forgot that UE4 splits viewport/render/game individually
mint monolith
Yeah thinking of it as basically like running a seperate game helps me solve a lot of problems
As for the emissive, check the material doesnt have some gameplay logic type stuff hooked up
But the LOD thing might fix both
sweet hawk
I will try using nodes once my UE4 stops crashing.
sweet hawk
@mint monolith yep that fixed it.

Why I see different things in viewport and in camera? In camera I can see SM trough landscape

Hey! Any1 here?
warm dune
Is it possible at all to layer record different properties of the same Blueprint actor (source) one at a time and using the same Sequence with Take Recorder? For example, if a BP actor has two properties (variables in a Blueprint) I would like to be able to record one of them, then stop and select the same Sequence so I can record the second property while playing the first one, layering the properties one at a time. So far even if I select the same Sequence to record on top (following the documentation under Using Layered Take Recording), Take Recorder creates a new sequence if the same object (source) is being recorded. Selecting each property individually in the source's Recorded Properties settings for each pass doesn't work either. It seems that layered take recording only works as long as the sources being recorded are different actors for each layer. Is this correct?
tight stone
Try turning off each-actor-in-a-subscene in the project settings. But the sequence you see when you open the take is the one played and recorded into so you need to make sure you've got the correct sequence as your source to play back
But you should be able to check the toggle on properties on an actor to control if they record or not
pale swallow
Doing a magazine cover and I gotta export a High Res Screenshot of just my static meshes/everything but the skybox. Best way to do this?
Was thinking make the skybox green and key it out, but idk, might bleed into my reflections
warm dune
@tight stone thanks for your reply. I did try all of that and even if I choose what properties to record (different ones for each layer I record) it still creates a new sequence instead of using the same one. It layers properly if the second layer is a different object but that's not what I'm after.
tight stone
It is always going to make a new sequence, that's the idea of take record
is each take is stored separately so you can go back and change which take you're looking at later
But you can choose which take you're recording from (and it is played back at the same time)
tight stone
can you record your screen and show what is happening
warm dune
With different objects it's possible to record them in the same sequence one by one
I will. Thanks
barren lagoon
what's the difference between focus distance and aperture? both look like they give the same effect.
at least on my end here with what i'm doing
tight stone
@barren lagoon same thing as a real camera. Aperture controls the range of depth that is in focus (higher number = lens open wider = more light = only a tiny amount of depth is in focus, lower number = more closed = less light = larger amount of depth is in focus)
While Focus Distance is moving where that slice of depth is
barren lagoon
got it. thank you friend! you being active in this channel is a godsend. Sequencer has been so fun to tinker with.
cerulean grail
Hey all, I have a question now that I really dive into the sequencer.
How do you usually handle characters carrying weapons or not ? It's impossible to use BP in sequencer so I can't really put the character i built with his mesh + his weapon (different mesh) directly in the sequencer. Do I always need to reattach the weapon in the sequencer manually ? It sounds a bit tedious. Is there a way to make a "prefab" with character + weapon easy to re-use in the sequencer ?
The way I'm doing right now is have a character mesh with no weapon and a character mesh with weapon, though it's a terrible workflow as the weapon needs to change sometimes π
gritty rain
Heya! How do i do a preroll for particles? I want to render a sequence with partciles already up in the air. But on my render they only start appearing.

@cerulean grail Dynamic Actor Rebinding. Animate a Spawnable copy of your player, rebind to the actual player instance (which is already set up) at runtime.
cerulean grail
@tight stone thanks I didn't know about the dynamic actor rebinding feature. I'll give it a try today and see if I can do what i want with it, as I don't have only the player but also other characters that are carrying weapons. Cheers !
tight stone
@cerulean grail If all of your characters/players share the same parent blueprint class, it might go okay. Basically Sequencer just takes the tracks that are there and tries to evaluate them on a new object... gets tricky if they have different components so if they all share a parent blueprint that defines like their body skeletal mesh and weapon skeletal meshes (and are just swapped out which specific ones per person) it might go ok
cerulean grail
They definitely have different components. Some characters have one weapon, some have two (shield + sword etc). Let's see how it goes, but that looks like the right direction
But they indeed share the same parent so as you said, might go okay π

barren lagoon
i haven't used cranes and rails yet, but what's the benefit of using them when you can just keyframe the transform of cameras?
barren lagoon
actually also begs another question. in what scenario would i use a crane over a rail (and vice versa)?
couldn't a rail theoretically do the same as a crane (and vice versa)?
tight stone
They're just there to provide constraints that physical camera moves often have
ie: Many real world cameras are shot on either a crane or a rail, cranes give you arcs relative to their dimensions.
The look of Cinema comes from more than just visual effects like color grading or lens settings, it also comes from the physical constraints used to shoot it
barren lagoon
i see. i'm just trying to wrap my head around it. it seems to me that a crane would be useful if you're trying to move your camera in a perfectly circular motion (like hands moving around a clock, essentially) and a rail would be useful if you're creating some type of sporadic "roller coaster" cinematic with perfect curves showcasing the layout of a scene.
but for perfectly horizontal or vertical movement, doing simple transform keyframing for a cinematic camera seems to still be the way to go
maybe i'm missing something
i have a soldier in my cinematic and i want the entire thing to be done in one shot (it's inspired by the movie 1917)
i tried using a rail but because of how close up and quick everything was the rail turned into a complete mess and was a hassle to be accurate with
so i'm unsure if a camera or a camera with a crane is the way to go
is there some benefit the crane would give me for what i'm trying to achieve?
tight stone
I would probably not use rails/rigs if you're doing a really long shot, it's probably going to be pretty hard to transition between them smoothly
hollow owl
what's the proper setup for a virtual production enviroment, to properly match the tracker position to the lens?
hollow owl
I dont think that the position of the tracker vs lens should be approximated, since the paralax between the camera sensor and the tracker is very important for movement matching, is there anyone doing virtual production that has a proper calibration tool?
violet igloo
anyone know how to change the camera res in a cine camera actor similar to in the regular camera
where i could just type like 2048x1072?
tight stone
I don't think the resolution actually defines anything, it's just a helper for generating the aspect ratio.
You can just type 2048/1072 in the field that says 1.9104 and it'll do the math
barren lagoon
using a standalone camera and keyframing it is working pretty well atm. what are some specific scenarios in which i would find it beneficial to use a rail or crane?
tight stone
@violet igloo In a cinematic camera it is based on your sensor size, change the Filmback. The sensor size is needed to accurately calculate physical effects for the camera.
