Silly question... How can I take a float and round to the nearest multiple of 32? (blueprints) I mean I can do it a long way just wondered if there is a simple way.
vale osprey
@digital badge there is node in BP "division with whole and remainder"
digital badge
ok thanks I will look into it
vale osprey
it will give you floor on positive values, to get nearest you need to check how large is remainder too, like if it's larger than 0.5 then Whole + 1
or divide by 32 and Round()

ruby chasm
guys, is there any way to take UE assets and turn them into FBX meshes that I can use in cinematics in, for example, 3ds max etc? I'm looking to put together a trailer for my game but I'd like higher-quality rendering for that using the same models you'd find in-game. These are not custom assets so I don't have them in fbx already.
cloud cobalt
It's probably not allowed by the license.
Also, exporting the mesh is one thing, exporting the material setup is quite another
ruby chasm
Would this work in theory?
I may just have to stick to capturing gameplay and then maybe colour grading it to put a trailer together instead. Or animate a camera in-game to capture it with.
fierce tulip
you cannot get the material, so you'd need to export all the textures as well and re-set them up
cloud cobalt
What about doing your game great looking ? Paragon for example uses the game itself for the trailer
fierce tulip
^
ruby chasm
I agree, though this was intended as more of a cinematic trailer and then a separate gameplay trailer would've been shown. I think it'll work just fine as being a cinematic trailer using gameplay, however. Thanks guys!
cloud cobalt
Well you can definitely do a cinematic trailer with UE4
And it can look just as good as in 3ds
fierce tulip
its actually why a lot of archviz and other companies are moving to real time, its faster, cheaper, and in most cases give a high enough quality.
ruby chasm

@foggy patrol if you have a folder with .ueassets, you don't import them into UE
you first make a backup of your project, and then copy the folder directly into your project folder, using windows file manager.
foggy patrol
ahhhh okay!
vale cloud
then, you re-open the project and hopefully everything will be there working. if not, THAT'S why you backup your project 😄

I am trying to use custom collision meshes for spline meshes. I thought I would subdivide my UCX collision mesh before importing it. The problem is when ever I import it UE4 simplifies my collision mesh to a box collision.

worn granite
Nah, nvm
plucky river
I only have about 60 verts in my collision mesh right now. But since they all are positioned on the same edge they just get removed by UE.
I found one stupid workaround for now. I just use individual box collisions for every subdivision I need. When used in a spline mesh these boxes get stretched properly. I'm not sure about performance on this though.
worn granite
You could try minor offsets, but if precision is required that won't work
But I'll stop with the straw grasping
plucky river
It somewhat worked, but it's not really feasible. Interestingly enough UE still created individual collision pieces when I checked it out in the mesh editor tool.

@fierce tulip Here's a screenshot of one of the many supposedly overlapping UVs: http://imgur.com/a/nVpkO
Note that on the other mapping channel these exact same UVs are also used, I don't have different sets. I don't really need any UVs for textures for this project.
Is it a bug that when I hide staticMeshActor s in my scene they somehow still get calculated by lightmass and cast shadows and all? I have a simple room with machinery in it. I want to make some lighting for the room and just hide the machinery while doing it since it takes much time to calculate lighting for the machine when I don't even have the mood for the room yet.
Or am I missing something?
fierce tulip
@plush yew thats a very veeeery poorly done uv-map though.
as in, automated by a poor program that does not respect texel density.
aslo, by the looks of it, it might easily be overlapping some polygons within those uv-islands.
id highly suggest to redo that uv map properly
because thats just a nono
plush yew
I hear you about texel density and I am aware of it. We'd need extra scripts/software for an autmatic unwrap with respect to texel density which isn't possible at the moment. The most party which you see are rather small and I think it might be okay for these purposes. They're not hero objects at all so for the time being that is fine. We really only are doing a proof of concept for a client on our own clock, researching how much could be automated by inhouse tools etc. The islands come from CAD data seams which are pretty accurate. I will dissect one of these objects and look over it though. But fgrom the looks of it it works.
fierce tulip
even if they are not hero objects, you are using less than 30% of a 64x64 texture lightmap, means the entire thing is only getting a few pixels of lighting information.
you could look at ipackthat if you are 100% sure no uv's are overlapping, as its quite automated but still requires some time.
if i was a teacher and someone showed me a lightmap like that, they would fail the assignment, not to mention if i had to hire someone and they showed me that.
plush yew
I hear you. I may look into packing with respect to texel desnity. The thing is It looks totally fine in the Viewport/when ingame. I just found it strange that it shows overlapping UVs by 20 to 50%! Which clearly is not the case. But I thank you for your insightful answers though. Thw hole lightmap idea is new to me since I am a 3D Artist and don't have to worry about stuff like that usually.
fierce tulip
if you can send me the file I can take a look in 3dsmax and see if the error is correct or not
plush yew
Before looking into external software I guess I'd rather invest the money into an automatic solution in-dec-software
I will triplecheck the file myself now ^^
vale osprey
@plush yew with a very low resolution light map, your UV might not overlap in their coordinates but will land on the same texels, this will lead to a bunch of problems like shadows or light leaking from one surface onto another
fierce tulip
that doesnt cause a lightmap overlap error though afaik
plush yew
Ah! So this message respects the resolution? I thought it only meant the explicit mesh UVs
If that would cause the error it would be understandable
vale osprey
let's say your texture is 64x64 it means that you need to have at least 0.015625 U and V distance between each island
plush yew
I jut checked one mesh, Ill send it to you which shows 34,6% overlap in UE but looks fine (apart from texel density) in maxc
You got a mail adress?
vale osprey
@plush yew I don't think this is the reason it throws error, I'm commenting just why proper unwrap is important

fierce tulip
just hiding isnt enough, you'd need to disable cast shadows.
plush yew
Who the f*** thought that was a good feature...
fierce tulip
hiding is just for editing reasons

all the red highlighted ones are mirrored uv's
need to un-mirror em
https://i.gyazo.com/9835ccb76a20e72248645e6800efd6df.png
and these are all overlapping
plush yew
hugh. how? lemme check
The red big strip on the left
it is one single side of the mesh
How can it be overlapping? I don't get it
fierce tulip
the top line's left vertex is at the bottom of that
plush yew
Overlapping means that one part of the UV space is assigned to more than one polygon right?
plush yew
how the f is that even possible? oO
fierce tulip
poor unwrapping :p
plush yew
but but but....wtf.
fierce tulip
and thats happening with a lot of the uv islands
and as for some of the overlapping, there are actually some additional polygons overlapping the spheres due to poor polygon distribution
https://i.gyazo.com/1e1a4505f03a617d7724d753b658620b.png that should never be a thing hehe
fierce tulip
that would be better
anyways, polygon wise, its extreme overkill hehe
15k for just that cylinder
now I understand it isnt for a game, and in theory for small scenes its still fine
also, some parts of the mesh arent even welded together O_o
plush yew
I know the meshes are clearly very far from optimal. But it is about being able to process manye objects from CAD to game engine without much work to do by hand. And the thing is these scenes are literally only a room. there is NOTHING (speak: nearly nothing) there except the product
I cannot weld automatically and keep the smoothing groups intact so I decided against it.
fierce tulip
you could go for dynamic lighting
vale cloud
heh I understand (been reading the discussion) but ... talk about overkill 😄
plush yew
I will need to check this in VR if the framerate is acceptable though but it seems like it
fierce tulip
would make lightmaps redundant altogether
vale osprey
yeah go for dynamic lightitng then
plush yew
Is dynamic lighting possible performance wise if you imagine 2k ob such objects like I sent you in the scene?
(Sorry I have little knowledge of game engines)
fierce tulip
might need to test, polycount isnt the biggest issue, mostly drawcalls and dynamic lighting, which might be a bit heavier on high polygon objects (?)
plush yew
The thing is one of our core competences is lighting (in max now, not realtime) and we want to kind of work in the same way if possible and achieve a similar quality
vale osprey
in a different engine our client used just single direct light and ssao to visualize 40mil polygons factory cad drawing - most likely you have to get rid of shadows too
plush yew
What would count as a high poly object?
fierce tulip
a cylinder with more than 100 polygons XD
plush yew
xD
vale cloud
lol
cloud cobalt
15k for a mesh is hardly unexpected on PC today
fierce tulip
bit jokingly ofcourse
vale osprey
@plush yew you can bake lighting into vertices and/or into texture in external software. Just need a custom shader to visualize this properly in UE4
plush yew
Oka yI have little boxes for screws etc here with 98k faces xD
fierce tulip
15k for a cylinder would make me doubt I'd need that person though :p
cloud cobalt
if it's just a regular cylinder yeah sure 😃
vale cloud
if I'm understanding your intention correctly, one big important thing that will contribute to that "high-quality" looks you're aiming for is material/shader work
you can probably get good enough results with dynamic light + PP
plush yew
It is mostly lighting to be honest. I dont need complex shaders but I may create them I I feel it being neccassary
vale osprey
@fierce tulip if models coms from something like SolidWorks then you don't really have a choice
fierce tulip
true
plush yew
@vale osprey They do.,
fierce tulip
though then id almost suggest getting instalod/sympligon to reduce em some :p
vale osprey
welp, I would bake in max then
plush yew
What would be the drawback of the dynamic light approach? Could I still get something like shadows from window holes in walls on the floor?
plush yew
Nah I need shadows from the CAD geometry on the floor
vale osprey
then you will cry
vale cloud
lol
plush yew
I rather go through the process of creating lightmaps better than to having resort to fakes etc.
vale osprey
well, you don't have to have lightmaps on everything
plush yew
Is the atuomatic lightmap creation algorithm of the FBX importer /UE4 the same or better/worse then the 3ds max flatten mapping?
fierce tulip
https://i.gyazo.com/98d0031bd53720879dfffae99417e6f2.png minute of work and saved you almost 15k polygons :p
vale osprey
on high poly machinery itself just rely on dynamic lights and shadows but for floor/walls you can use lightmap
plush yew
DUde I know. But there are huge amounts of objects like these
I know how to properly model
fierce tulip
ue4 uses the first lightmap to generate the new one, so if the map for the texture is crap, so will the lightmap be
plush yew
But it is about efficiency
fierce tulip
and max's unwrap auto tools are crap as well
plush yew
Of course I could remodel all that crap and be done with it.
vale cloud
@fierce tulip crap, but definitely better than the example shown?
fierce tulip
that also depends on the first uv map
vale osprey
it can't do much if geometry is not split properly
fierce tulip
it can actually generate that exact map
vale cloud
no, I mean, max can generate some ineficient UV maps when using one of the auto tools, but it won't overlap for sure
plush yew
Yeah that exact map was basically taking the UVs of the CAD geometry an d packing them
fierce tulip
it sometimes does
plush yew
I rather have inefficient than overlapping xD
I will try to use the flatten map feature
I got a script running unwrapping it all-.
plush yew
Could you recommend a plugin/Script INSIDE OF 3ds MAX (meaing purchasable or downloadable) to do better auto unwrapping of mass objectS?
plush yew
I'm talking 3k objects. Most of them are instances though. It comes down to about 200 uniques
Yeah I have used max a similar amount of time
fierce tulip
unwrella, xrayunwrap..
plush yew
It never ceases to demoralize me.
Unwrella in hard surface mode is barely better than the max default 😛
vale osprey
@vale cloud auto unwrap can't split UV in an intelegent way, not all the time at least
fierce tulip
its about time we get proper AI for computers so they can do stuff that we ask em to
vale cloud
@vale osprey true, as I said, definitely inneficient in many ways ... but better than overlapped UVs, no?
plush yew
I cant weld them though, not reliably automated
fierce tulip
"sort X" "sure master luos"
plush yew
@fierce tulip True ^^
vale cloud
some time passes "Make MOAR ice shards, punny human!" "yes master 😐 "
fierce tulip
WHUAHA! moar ice
vale osprey
@vale cloud that's how you get overlapped UVs with flatten
plush yew
Really? Overlapping with flatten? I mean of coursse Id pack the UVs afterwards
vale cloud
flat and repack gets you overlap? I'm definitely lucky then, or I haven't tried complex enough stuff 😄
vale osprey
well, make a cylinder out of booleans instead of primitive and see how it will be cut
vale cloud
note: I mean "physically" overlapped UVs, not overlapped in the sense of poor lightmap res will overlap them
fierce tulip
id suggestto look at xrayunwrapper, its cheap. though not sure if there is a demo
vale cloud
max never liked booleans ... it's genetic 😄
vale osprey
yes, physically overlapping because one triangle on one side can be connected to another on opposite side
fierce tulip
though it seemsyou'd still need to add your own seams for xray
thats useless
(in your case)
vale osprey
so if it can't separate surface by a nomal threshold for example, then it won't be able to separate cylnder caps into different islands
like try it capsule 😄
but again, boolean not primititve as it cheats with primitives
plush yew
I think I will give the flatten UVs in max a try first. Thats what I had scripted first anyways and is just commented out when I saw that the CAD data came with some more or less sense making UVs
vale osprey
@plush yew are you targetiing super realistic look?
vale cloud
not to contradict anything you're saying, but really, max never played well with booleans, improved alot after proboolean, but still ... I try to stay as far away from them as I can
fierce tulip
try Jbools plugin, makes working with booleans a lot better in max
plush yew
@vale osprey In an ideal case yes, but since this is on our own clock Ill go with mostly realistic looking for now 😛
vale osprey
cause I'm not sure that UE4 is a good choice for that kind of visualization
I would get some RFP from Delta Gen for comparison
imho you need to mod UE4 quite a bit to get good looking high poly models - strip out all unnecessary things, replace SSAO with something more aggressive
combine ssao with per vertex AO
fierce tulip
https://i.gyazo.com/d8477c9252cd53f232a38328121be0be.png flatten uv from max
https://i.gyazo.com/886895534cc739689e6e9d589565f85d.png
steamroller
vale osprey
you can bake per-vertex AO in something like this:
http://www.faogen.com/features.html
or directly in Max, we used max but this was way before you could use GPU to calculate it
vale cloud
yeah I remember testing that a long time ago
also this
(if I remember correctly, just a quick google, sorry if not accurate)
vale cloud
yeah for AO it should work great with high-poly ... problem with vertex bake and lowpoly is the "stretching"
vale osprey
yeap
plush yew
So that flatten map hsa overlapping UVs now right?
Hm my flatten map looks different. Did you use Unfold mapping?
fierce tulip
nah no overlapping uv's in most cases. but it still unwraps crappy.
plush yew
From the max help:
"Flatten Mapping uses an angle threshold to define the clusters and the clusters will always be contiguous faces. This type of mapping will generate mapping that does not overlap so it is useful for baking textures and lighting. "
vale cloud
you'll only get proper UV unwrap when you do it yourself ... and even then... 😄
plush yew
Of course.
What the F my flatten mapping now does something completely different
this buggy shit.
vale cloud
but yeah, from my experience, flatten UVs aren't supposed to overlap ever. But I absolutely believe @vale osprey and @fierce tulip when they say it does 😃
plush yew
I guess maybe it works good with unwelded CAD geometry
and not so goodd with welded xD
but a few small percent overlap I dont care about at this stage.
vale cloud
@vale osprey supose I did a vert bake of AO ... how would you go about putting that to use in UE with dynamic light?
(being an eternal n00b, I never got to really using and understanding AO properly in UE) 😄
fierce tulip
well, its the few cases where it did happen that always stick with you @vale cloud but so far its been sporadic.
fierce tulip
just multiply vertex color node with whatever
vale cloud
lol what ever? 😄
fierce tulip
could be albedo
vale cloud
that's not AO 😐
fierce tulip
yea, creative expression
vale cloud
that's dirtying the diffuse with the AO map
fierce tulip
well thats the thing, you multiply it with albedo for some easy cheap ass ao
you could try just plugging it as the alpha of a lerp, and point it at the ao
vale cloud
but that will affect even direct illumination of the surface
and AO should just affect indirect illumination, or lack thereof
wary charm
Hello there ... any experience UE4 dev here? I'm trying to build a PC from scratch and thinking of pairing i7 7700k with 1070. Would you recommend I go for a six-core cpu instead of 4, even if the clock speeds are lower?
vale osprey
@vale cloud UE4 materials have separate input pin for Ambient Occlusion
vale osprey
no idea 😄
vale cloud
lol ok 😄
vale osprey
you can always make your own custom shader
fierce tulip
you need to enable it, there is some documentation on it but cant find it
AO does work
vale cloud
😮
vale osprey
" Also the Material AO Channel will only impact static indirect lighting, lightmaps and will not affect ambient cubemap, for example."
so plug it into emmisive too! 😄
and albedo
fierce tulip
and metal!
vale osprey
yeah!
fierce tulip
heck, create 12 customuv channels and BAM PLUG THAT SUCKA IN
vale cloud
lol
well, I was kinda hoping the damn Ambient Occlusion input would be... you know ... good for plugging in AO map and actually do something useable with it?
the guy in that thread I posted has a good illustration of how it's not working 😐
vale osprey
I would try to combine it with other things, like mask your roughness for example
vale cloud
for sure, but that's basically PBR hacking ... I was kinda hopping there would be a "proper" solution 😃
vale osprey
it's not hacking, its how it works 😄
welp, I did wrote earlier that you have to mod engine 😉
vale cloud
lol ... well, I'll always take you guys word, but ... what does roughness of a surface has anything to do with it not receiving illumination? I mean, it can have, in some cases ( microsurface features and all) ... but, take that example, cube, sides fully not being hit by direct light ... zero val plugged in AO ... should be black or near black surface 😛
vale osprey
because low AO value indicates that surface is blocked from light, so your reflection need to be dimmer
we can argue a lot how it's suppose to be, but keep in mind that PBR is not a standard
and it all depends on which actualy shading model is used
vale cloud
true that
but in that cube case
I guess it has more to do with the fact that the engine simply disregards the skylight when calculating AO from that material input
so basically the skylight floods it over 😄
vale osprey
so if we take standart material:
I would plug a mix of AO and roughness into roughness, then into AO (so it works when it can) and just a bit of it into emmissive
which is not ideal as you don't want to have a heavily pronounced AO on the lit side
but it's better than this (let me grab le screenshot)
ssao is so subtle here that you have to switch it on/off to confirm that it's even there!
vale cloud
really subtle
main pewter
hello guys, someone around who can help me with a (thought) simple material prob?
I've a modelled car cockpit and whant to have a dynamic mat. in which I can set some symbols to glow independently from another (ex: turn signal left + head light indicator, or only turn signal right indicator)
I've a ao texture and one lumination for the emissive, but i dont't get to mask out some of them independently
any ideas?
vale osprey
@vale cloud and I would prefer ssao like this:
http://3dvrm.com/ssao/main/sm_ssao_only.jpg
vale cloud
can't you aproximate that with playing with the SSAO values?
vale osprey
there are two values intensity (max 1.0) and radius
this is at intensity 1 already
radius doesn't chnage it's contrast either
and I actually had to provide only Base color to see any ssao at all
with metallnes and roughness set to some value it won't render it at all
thorn topaz
Anyone familiar with version control inside ue4?
vale osprey
@main pewter you could literally cut those symbols using geomtry and then flip color of material of flat plane behind them
vale cloud
@main pewter there is a material func that generates gradient bands ... with a bit of calculation you can use that to multiply by your mask and plug on emissive
let me see if I can get the correct func link
even this could be used
(but I was referring to another one that I can't seem to remember the correct name 😄 )
@fierce tulip I know, I know ... you need to stop chatting ... but if, by any reason, that specific piece of documentation where you enable proper AO functionality, happens to, say, hit you accidentally on the head while distracted ... please let me know 😄
main pewter
😃 ok, thank you. but I have no idea to start with this. my texture (ao and the lum) are the complete car. I've create a new one with correct UVs to only show the symbols (not part of the other textures). so I get the turn signals in my green, light indicator in my blue channel as a mask (to multiply with color and feed into emissive). no i need to mask only the left indicator in my green channel when turning right - for example 😃 I'm totally confused...
vale cloud
yes
now
lets say your TurnLeft mask is at postion 0,5 U 0,5V (basically in the exact middle of the texture)
you need to generate a radial gradient with center 0.5, 0.5 and a radius big enough to cover that piece of mask
then you multiply said gradient with your whole mask
and you get just the mask for the TurnLeft
basically, in that way, you're masking the mask 😁
main pewter
ah I see 😃
but how do you get to the position of the center in uv space? i fire up my photoshop and get the pixels and feed that as a percentage of the height/width into the function?
sorry fur asking dump questions - materials/uv/modelling ... we don't get to be best friends ever :-p
vale cloud
lol no prob ... so, whatever your width/length in pixels, your UV space is 0-1
so if a texture is 1000x1000, pixel 500,500 would be 0.5U 0.5V
main pewter
ok - I'll try that 😃 thanks for your help!
vale cloud
no prob ... but ask for other opinions, this might not be the better way to solve your problem 😉
but to be more specific, if you want to know UV coord of a specific point in a texture
x / width , y / heigth
main pewter
I'm fine with that if its working 😄 took already to much time for a simple thing like that blinkiblinki 😉
only need to check performance if this is a "cheap" thing (doing it in VR) I think a dynamic material is one of the cheapes for this effect so I think it is a nice way to go
vale cloud
yeah ... well, this way you'll be adding at least one procedural node for each "signal" you want to mask ... you need to evaluate if it's cheaper that way, or simply using more textures
lets say, you only have 4 signals
you can simply add a single texture, and put each mask on its own channel
how many signals will you have? 😃
main pewter
hm...I guess around 10 😉
vale cloud
if you're really doing it on the material, I'd say ... you either use the gradient node, or you add 3 extra textures ... or you do some fancy calcs on the UVs, but that voodoo is a bit above my league 😄
main pewter
😄 looks like I'm getting what I need with the gradient. so i'm fine with that 😃 it would be great to have it not round but a square but i think i can deal with that. or would it be posible to have a white square in a texture and position that with the texture-cordinate node as a stencil over the other material? don't know how to explain in english but you know that calendars with the red square you move to the current day? something like that 😃
basically while writing ... maybe I should take a quick look how the sprite system works in UE ... it sounds somehow like a sprite 😃
vale cloud
yeah I understand what you're saying, and yes, you can definitely do that
just get a TextureCoordinate node, break to float2, then Add to x and to y seperately the amount you want to move in UV space
main pewter
hm - that would reduce my amount of textures needed - just a little list of uv coords for the symbol i need next and where to position my marker to let this shine through my emmissive 😃 thank you! I need to go researching 😉
vale cloud
then just plug that into the UVs input of your "moving" mask
(AddU and AddV would need to have the correct amount you want to move in UV space)
main pewter
AMAZING! Thank you so much! going for a try
vale cloud
nice 😃 let me know how it works out 😉
lol actually ... if your "moving" mask is like, a small white rectangle starting exactly at 0,0 of your texture
there is a easier way ... let me test 😄
nope, forget it, was being dumb ... best way I know is really that ^

Hi guys. For those of you who released or plan on releasing, have you done an EULA window in your game when you start it or something like that ?
According to Epic legal guidelines we're supposed to do it, so I wonder if there is a bult-in tool for that or if that has to be in the game itself
UDK bypassed that because it created a full installer, but UE4 doesn't, and we'd use Steam anyway

Anyone use Anim Montages a lot? Was wondering if there was is a way to update an animation (eg the length changes) and havng anim montage sections auto update and snap in place to the end point of an animation
Right now whenever we update an animation we basically have to rebuild the anim montage from scratch, re-aligning all the section markers and then snapping the anim notifies back onto the section markers
We have a lot of loop in and out points all strung together in one anim montage, and there's no visible "reload" button that updates the animation length and retains all the relative information marks

Hey guys, How would I make sure a visibility trace done from blueprint takes the Displacement done in a shader into account? I've got this problem where a trace goes through the surface, and "hits" the surface BEFORE it got displaced in the shader.
This is a landscape component without any shader displacement, which returns correct results
Here the same landscape, but with displacement in the shader. Which returns incorrect results
safe shoal
You can't. You can't read the shader displacement on the CPU
All displacement is done GPU-side only
Shader Displacement just moves the pixels / verts just before they're drawn to screen - so CPU can't know about it.
@main lotus
main lotus
Alright, makes sense. Is there a way around it other than sampling the heightmap, and adding it as offset?
safe shoal
The way around it would be to sample the Displacement Heightmap on the CPU the same way it's done on the GPU, then modify the position that the line trace returns. But that's expeeeeeensive.
cursive dirge
option is to match the mesh closer to the target shape
safe shoal
^ Or that of course
cursive dirge
it doesn't really look like you are doing much good with tessellation + displacement there
don't use it on flat plane
main lotus
Not on this particular area on the landscape. But other parts have a lot more @cursive dirge

you could still try to find some middleground, make sure the base mesh is always somewhat close to where you want the feet to be at

foggy patrol
I wondered something
I hear quite a lot that motion capture is quite expensive, right?
raven cedar
Depends on how deep you want to get into it you could do it for 10 bucks or you could do it for a thousand bucks or you can do it for ten thousand bucks
foggy patrol
But why the fuck don't companies just grab a camera, attach it to their heads with some construct stuff, turn on the cam and let them act out the scene. This will show the animators a reference of how the emotions look, how the muscles work, how the lips move at certain words, even if they have to hand animate it themselves.
Aye
raven cedar
Yeah that's been done for a decade with socks and video cameras
foggy patrol
Then why are we seeing so many big games that absolutely suck with facial animation?
raven cedar
But you're also making a distinction there about facial mocap versus mocap
Because facial mocap is not the same as general gross physical body mocap
foggy patrol
That's true, I understand that a full body mocap (which is used in Beyond two souls and the Last of us if I recall well) is WAAYY different.
raven cedar
For a good facial mocap you need around 30 tracking points for physical body mocap you really only need about 12
foggy patrol
Aye
But then again, if you go for the really cheap option with just a camera for the face you don't need those points. Get 3 cameras for 3 angles and you can study the emotions way better. It might not insert the emotions into the game as the animators have to hand animate it, but still.
foggy patrol
Oeh, let me look into it, one second
YEh they did this, which is full body
And this to capture the facials
raven cedar
Yeah they're just switching to Infrareds now that's been in use for a couple years as well
foggy patrol
Aye. But why are so many companies not using it? Not even the simple version that's just recording the facial features? Mass Effect, despite it getting properly patched now, wouldn't have looked the same as it does now WITH the recording, as example.
raven cedar
It's come a slight way since having to use a magnetic setup with a full body suit and a 20 by 20 area hand keying crap in kaydara 20 years ago
You're asking a lot of different questions here
Like it's easy to hindsight a business decision that started five years ago
foggy patrol
Aye.
raven cedar
There's all manner of questions there is to pipeline

Proliferation of Technology
It's not just a simple as why didn't they just
cloud cobalt
Also, projects like that are pretty much like trains. Once it's on the rails, you don't usually take it off to change something and put it back on
raven cedar
Yeah a lot of those big budget Productions are simply turn key
cloud cobalt
If you have a running steup to create animation, usually you don't start over
Btw the animation in ME:A isn't bad because of tech - it's bad because of time 😃
foggy patrol
Yeh but they already have the voice actors. All they need is to plant something on their head to holds a camera, insert a camera (which can even be SUPER cheap) and record their facial features. I'm just talking about standard cameras here with standard recordings, nothing that will pre-animate the faces. But it'll gave the animators something to work from, a recording of how the animations look like. I get that when you are already a few years in you don't just change it. But why didn't they do it from the start?
That's very true
foggy patrol
I'll give them that the new patch that launched is amazing. The eyes look so much better, the "my face is tired" flows so much better. Like, they are fixing it amazingly.
raven cedar
It's simply pipeline like strangers said if you already have a pipeline that's established and working trying to retool a pipeline for something like that is just a monumental work and if they don't want to invest the money into retooling that part of the pipeline it's just not going to happen
halcyon marsh
please i have a height texture how can i use it in my material
raven cedar
And I only say that as a pipeline supervisor
halcyon marsh
cloud cobalt
Height maps are not the most common thing to use in Unreal
You should create a normal map instead
foggy patrol
Hmmm. Well, it's a shame really ( @ the previous subject).
cloud cobalt
Or use something like crazybump to convert it
foggy patrol
Thank you for answering my questions though 😄
raven cedar
Thanks for asking it makes me almost look smart
foggy patrol
No worries, I really enjoy such convos!
cloud cobalt
Height maps are typically not used in UE4 - normal maps are a better replacement
At least in the context of regular meshes
crude rock
does anyone know why i cant turn around properly after enabling and disable mouse cursor?
halcyon marsh
yes but when i download the material they give me also the height
cloud cobalt
You don't need it
halcyon marsh
why they give it to me x) ?
foggy patrol
I was going to suggest the detail textures but even that's lacking the height.
raven cedar
Turn on displacement and plug that into the world displacement
halcyon marsh
they said it is for ue4
cloud cobalt
Well it's up to you
raven cedar
Go to the properties for the Shader itself scroll all the way down to the displacement tab open that up and turn on displacement
Then just plug your map into the world displacement
Now it's not going to do this magical thing where you going to get this perfect displacement like you think you're seeing in that map
cloud cobalt
Either you use tessellation and do what @raven cedar says, which is going to add some cost, or you just use the normal
raven cedar
But that will get you 90% of where you want to be
crude rock
My mouse input is still locked to the screen bounds after disabling the mouse again. does anyone know why? it makes it so i cant turn around properly.
halcyon marsh
@raven cedar
halcyon marsh
if i want how to do ?
where i have to do the input
for the height
i just want to see the !=
cloud cobalt
Do this
And then enable tessellation in the material (use "triangles" for the tesselation type)
cloud cobalt
slower performance
Mostly, it's not efficient - you should do a more detailed low-poly, bake a normal map, and simply use that. It's more predictable, looks better, it's faster
Of course you can't do that if you just download the assets
halcyon marsh
why you use 10 and 33 for distance what does it mean ?
cloud cobalt
That's the itnensity of the displacement
cloud cobalt
The 10,33 is just a single constant
Not a 2vec
FYI, the errors normally show up in the bottom pane so that you can interpret what they mean
They should be telling you something like incompatible types
halcyon marsh
@cloud cobalt i dont very understand the Distance and TesselationMultiplier i am new in material what it allows me to do
because even if i change TesselationMultiplier nothing happen
cloud cobalt
Did you enable tessellation in the material .
halcyon marsh
oh i see the distance
distance i understand
with distance value change
it gives me more tesselation
but TesselationMultiplier i dont see any change

crude rock
@plush yew im working as a VP engineer in a VR company and i partly agree with but strongly disagree with other things. VR, as it is now, is kind of a gimmick and it's very expensive. But what VR brings to the table is revolutionizing. We are using it with Archviz and education, where VR provides an unparalleled experience and understanding of the digital world. This is something that can't be replicated on a 2D screen. When it comes to learning, we've noticed a 70% increase in learning ability (learning speed and retention) compared to ordinary teaching techniques.
For games, it might not fit that well into an FPS or similar genres, where movement and speed is key, but it does bring a new dimension to storytelling. I predict that within 5 years, VR will be a mainstream medium, that does not replace Screens, but compliments it and enhances digital content.
plush yew
@crude rock Yeah, I agree with you. I think it is good for education and many other fields such as training in military. However, I don't think it is good for gaming. Just my opinion.

Guys, does anyone have any idea why a skeletal mesh might be the wrong scale after importing, unless "T0 as ref pose is checked"

How do I change the pivot point of that red static mesh (it's a cube scaled down as an actor BP component) Normally I change the pivot point in the world view
light thunder
Is there some BP node I can use to offset the angle I'm rotating from, or do I need to build a model of the needle and set the pivot point in something like Maya or Blender?
vale osprey
Placing pivot in Maya or blender would be the best
You could try moving pivot on object placed in the level in editor, then export it as fox and import back
Another option is to add it as component into BP and move it in relation to the root component
If it's already in BP add scene component as parent to your needle, move needle in local coordinates and then rotate scene component

@vale osprey I made a new model in Maya and moved the pivot point but Unreal isn't using the corrent pivot point it seems
spice urchin
might need to delete history
light thunder
In maya or make a new actor component?
spice urchin
in maya
maya is notorious for saving ridiculous amounts of old data on locations etc so it can have extra "undo"
light thunder
here is pivot point, I export to FBX... am I missing a step?
spice urchin
yeah
put it at 0 on grid
that's your problem
just snap it
or go to the little x y z location fields in upper right and set those to 0
light thunder
Like so?
light thunder
Hmm.....the other static mesh rotated fine but this seems like it's moving on a different axis
worked fine before, the pivot was just off on the cube
so it would rotate around the center of the SM instead of the end
and why for the love of god does Unreal not let me rotate actors in the viewport of a BP sometimes...I've never figured out...I can manually put in numbers in the transform section but the viewport is like, "Not this time chump!"
vale osprey
Is it oriented along the X axis in Maya?
light thunder
uhhh
Hypothetically speaking, just for, um, academic purposes
Assuming it wasn't oriented ....
Yeah the whole axis seems a bit wonky....I can't seem to use the viewport to rotate the actor and the transform values don't seem to correspond
See here where I rotate along x axis but it also seems to be rotating with a different axis
you can see that I was pretty much perpendincular in the previous image
vale osprey
If it's not oriented then pitch/yaw/roll don't have their meaning anymore
light thunder
(or parellel, whichever makes sense)
Parallel I guess
okay, how do I go about oriented it in Maya (I can PM if you don't want to clog up UE general chat)
vale osprey
Check in Maya that you don't have rotation on pivot and that model is aligned with x axis
Do it like a habit - will avoid headache
light thunder
How can I tell exactly if the rotatoin is on pivot?
vale osprey
In Maya not sure
In max there is separate control for pivot position and rotation
Actually, if you are not using skeletal mesh then rotation of pivot is irrelevant
light thunder
Hmm...
The the reason my needle is disappeared is just because it's not completely parrallel with the plane behind it?

Okay, I seemed to get that but here's the issue -
That's the node that is moving the needle ...you can see it is set to 0, which I hope to god is relative and not actually changing an angle to zero, which i suspect thinking about it, it might be
and we broke everything...
that's at play time
I guess when I split that vector pin, I didn't think it would zero out everytyhing, I just wanted NO Change
vale osprey
That node sets world rotation
light thunder
it was working fine before but I split the pin
vale osprey
Switch to SetRelativeRotatin
You can merge it back, just right click on it, there is option
light thunder
close...how do I connect this to just one value?
when it is split, it sends a zero to every angle, (for example, before play, the angle of the static mesh is 140
spare topaz
is spatial voip possible with only BP?
vale osprey
@light thunder
that yellow input is a vector, not a single value
split rotator on SetRelativeRotation node and connect green output to Roll, yaw or pitch
light thunder
@vale osprey I did that but the zeros that are there are rotating the object to an angle of zero
I know because i left the entire thing zeroed out and cconnected it and it MOVED the needle
vale osprey
not sure what you mean
you can set one of those pins to a 90 degree rotation, if it doesn't rotate around proper axis
is your plane rotated too?
light thunder
My question is this
if the relative angle of your option is 30, 60, and 270, for x,y,z respectively
and you SetRelativeLocation of that actor with new rotatoin of 0, 0,0 , it is going to rotate on all axis, correct?
vale osprey
correct
light thunder
so I would have to GetActorRotatoin and just pull the pins out of there and put them into the setnode?
vale osprey
well, yes but only if you rotate around single axis and in limited range
the easiest would be to rotate your needle only around single axis
light thunder
yes, how do I do that?
vale osprey
for this, you can oriented your plane, such that it faces X axis
so X axis is like normal of the plane
then rotate needle in maya, so that it faces along Y axis
now if you make it a child of the plane, needle will be parallel to the plane with 0,0,0 rotation
after this you can animate it just with relative roll value
if you don't to re-import, add a scene component as parent of the needle
and rotate scene component such that needle with 0,0,0 is parallel to the plane
light thunder
this seems to have worked!
but I am copy and pasting what you said to my notes so I can build things better in Maya
vale osprey
try to roll it over 90 degress, see if it still works
light thunder
seems to I jsut need to fix some blueprint nodes
The problem is, it immediately updates the new rotation because I have it sent at event play, AND updated when the valve moves
There we go, that did it...now I just have to figure out hte right number to mulitply by
I actually could REALLY use an engineer's help, this isn't even Unreal so much as basic math....let me describe it
vale osprey
trouble with animation?
light thunder
I need to get corresponding rotation based on the pressure coming from that line...so for example, at begin play, the master pressure is 100... and as the Valve opens, it scales with the pressure, so a half open valve would be at 50 PSI, and fully open would be at 100 psi (I know this isn't the way real pressure is, just as an example thouhg0
vale osprey
you could normalize your pressure input and interpolate rotation from there
so for example your maximum pressure is 500 PSi
light thunder
C:\Users\Player of Games\Desktop\Screenshots from Jing\2017-04-07_1410.png
vale osprey
divide incomming pressure by maximum possible pressure on gauge
so pressure_scale = pressure / max_pressure
pressure_scale will be in 0..1 range
then add node called LERP
light thunder
what type of variable is pressure scale? float of 0 to 1 range you mean?
vale osprey
set minimal and maximum roll on it and input pressu_scale as "alpha"
yes
you don't need to store it anywhere
light thunder
a regular lerp or lerp rotator?
vale osprey
just regular as you provide roll only
you could use rotator but then rotation on other axis need to be provided into it
light thunder
got a bit confused for a second....the pressure scale variable...is that set to 0 to 1 or is it set to the incoming pressure divided by the max pressure?
vale osprey
incomming / max pressure
vale cloud
^that will give you normalized pressure (pressure in 0-1 range)
vale osprey
what I mean is that it will be in range of 0 to 1 because of such division
light thunder
so i don't use a normalize to range node correct?
vale cloud
(sorry to barge in, I've been watching your discussion 😁 )
light thunder
the more the merrier, thank you for helping
vale osprey
well, you could clamp it to 0..1 but this might hide some issue
like if pressure is negative you should see bugs
clamp will set it to minimal pressure instead
light thunder
what am I setting for A and B on the lerp?
vale osprey
minimal and maximal rotation of the needle
light thunder
um, what are those?
vale osprey
ohh wait, this won't work 😄
light thunder
like, the increments to move it in? I thought that would be based on ...
light thunder
This is what I have
halcyon marsh
Someone know how to get variable from Level Blueprint into oter BP ?
light thunder
I DO!
halcyon marsh
how
vale osprey
rotate your needle in editor into minimal possition of pressure and copy/paste values of rotator into LERP A
then the same for maximum value
light thunder
so my minium value is 135 correct?
vale cloud
vale osprey
@light thunder you can right click on"Rotation" and copy it
vale cloud
tl;dr ... probably not possible to get them from Level BP, better store them in Game Instance
halcyon marsh
@vale cloud but the problem is that the game Instance is not for that
game instance is for store variable when level change
light thunder
how do I pipe this out then @vale osprey
vale cloud
use Game Mode then? 😃
light thunder
Because I don't want to rotate the other values to zero, that will screw it up
halcyon marsh
--" how to thank you x)
light thunder
nevermind i'm an idiot
halcyon marsh
because i have BP_ManagerSomething and i always do a get all actor from class
vale cloud
anyway, even if you use Game Instance, you can get them in the level BP, store whatever value you want (at begin play?) and then you can also access it from whatever actor... if you want to change it when you load another level, just do the same for the new level
halcyon marsh
it means i have to do it also in the GameMode
yes i understand what you tell me
but even if i do it
i will use the
get all actor of class
and i want To dodge it
vale cloud
heh well, without knowing xactly what you're doing, I can't really understand... you asked "Someone know how to get variable from Level Blueprint into oter BP ?"
vale osprey
@light thunder split output
pallid compass
You can blend shape with just 1 object right? you dont need multi objects?
vale cloud
to what I replied "can't, but you can store in GI or GM, access it from level BP at begin play, set it, and then access it from whatever actor and get it"
light thunder
@vale osprey Okay, it is moving the wrong direction....I tried multiply by -1 but that just made it jump to the other side (makes sense I think)
and it doesn't seem to be interpolating accurately
halcyon marsh
@vale cloud oh ok so i have a class BP named BP_SaveManager and other named BP_Position Manager and i need a ref from them without using the "get all actor of class"
vale osprey
ahh, flip A and B then
light thunder
very small amount of movement...I moved the pressure up and it's not changing the range at all
also, does Unreal compute 410 as the same as 50 for a circle/rotator?
I checked the transform and it seemed to
halcyon marsh
@vale cloud or without drag and drop them into the viewport i just want to know if it is possible ?
vale osprey
@light thunder yeap
to avoid confusion better re-import needle such that you don't need to rotate anything but roll
light thunder
that's not the issue I think though
vale osprey
because there is a problem when you rotate one axis by 90 degrees
light thunder
it's rotating just one axis though
vale osprey
ok
light thunder
the moment the valve was opened just a bit, it sent it to the A node which was the 50 degree one
but it is on the wrong side
halcyon marsh
@vale cloud i dont know if you understand what i want ^^
vale cloud
@halcyon marsh probably not ... also I'm not the best person to help you really, not much more than a n00b myself 😐
light thunder
You can see the value of the incoming pressure there
vale osprey
@light thunder so what is the value of pressure_scale when you start it?
light thunder
0
light thunder
vale osprey
@light thunder
then it should output A
light thunder
wait, I need to pipe the pressure scale to A? wat?
vale osprey
the idea that it interpolates from A to B using alpha
light thunder
yeah, I get that it should go from a 135 angle to 410 (the 50)
based on the alpha value
maybe multiple alpha by -1?
for the right rotatoin direction?
vale osprey
so when Alpha input is 0 you get A on output, when Alpha is 1 you get B on output, when it's at 0.5 you get middle
no, alpha should be from 0 to 1
you can simple swtich A with B
light thunder
I did that, now the neelde starts in the correct location but it moves the wrong way and it doesn't seem to scale
light thunder
yeah, my incoming pressure now is 400 but the needle moves the same distance
well, the problem is, it's going the shortest path
vale osprey
while Shortest path is off?
vale osprey
it's fine, you can trick it by giving it different angle, like 360 + 50
light thunder
son of a bitch it works
vale osprey
the problem is that your needle is not rotated to 0 degrees from the start
light thunder
incoming pressure is 400, valve fully opened! ...IT"S ALIVE,,..ALIVE I TELL YOU!!!
light thunder
Valve open 50% (gated down) pressure is at 200.....THANK YOU DUDE

@safe shoal seriously, i love you. i want your babies. i want to carry your name, and i want you inside of me. /me plucks one hair and eats it
vale osprey
@light thunder no problem!
halcyon marsh
Someone here use a BP class only for references ?
pallid compass
I am really stuck with blendshapes/morph targets can anyone help me?
light thunder
@vale osprey how hard would it be to put a smooth curving animation to that needle rotation?
vale osprey
you can use Intrp nodes for this
but you have to call them on Tick
so basically you get that out put from LERP, this becomes input for Interp node
delta time comes from Tick event
target is output from the Lerp that you already have and Current is a value that you set as output from this function
light thunder
wait, I put the return value right back into current?
vale osprey
yes, output becomes input on next calculation
light thunder
And what if event tick isn't set to execute anything
vale osprey
