how do I allocate more RAM to unreal
worn granite
Is it not using your full amount of memory?
velvet estuary
Not sure but I would assume so
versed pawn
Thanks!
still bough
@rotund harness Unless you have taken steps to make UE run in 32 bit, there's no way or need to "give it more memory"
@rotund harness what issue are you having that you think more memory will solve?
ah damnit
worn granite
Getting an out of memory error on load
I've suggested loading into a different map and reducing costs
velvet estuary
Ill see what happens if I try making a new map and teleporting into the map I want to play
still bough
that's going to be some other problem
18446744070340949812 is not a correct amount of bytes to want to allocate
worn granite
I missed that, I guess ๐
still bough
there's data somewhere that's telling UE how big something is, and therefore how much memory it needs to allocate, and that data is corrupted
it's probably data corruption in the level asset itself, but it could be memory errors elsewhere stomping on that bit
velvet estuary
its weird because this map seems to only work on on computer
Uh, however you spell Wierd.
velvet estuary
Wait Unreal is running in 64 bit, is that a problem?
still bough
no
well
probably no
if it works when running in 32 bit mode then its a bug in unreals asset loading code
but it's probably not a bug in the code, it's probably corruption in the file
velvet estuary
but the file cant be corrupted it works fine on my college computer!
still bough
mmm try deleting your derived data cache
velvet estuary
but uh, just for refference wheres the derived data cache?
thin haven
project name/intermediate, I guess
still bough
you should delete that too, but there's a global one stored in your user profile
velvet estuary
I dont see a derived data cache in here
there are cache's but none of them are derived

try copying the project afresh from your college computer? the file might have gotten corrupted on the computer where it doesn't want to run. sounds like RAM/HDD problem on your other computer then
velvet estuary
its all saved onto a USB
still bough
usb drives are notoriously unreliable and will corrupt your stuffs
don't keep stuff you can't replace on them
velvet estuary
but heres what i dont understand
Works fine on my college computer, but every other computer craps out
And all of it is kept on this USB
So
Im just dumbfounded
thin haven
you launching from the same usb on the college computer?
velvet estuary
yep
thin haven
really weird, I would say the usb is corrupted judging from the error you showed, but it's not if your college computer can read it ยฏ_(ใ)_/ยฏ
either way, I'd copy the stuff elsewhere in case the usb drive fails
velvet estuary
is this Schrodingers USB?
Or is Schrodinger the wrong analogy?
Screw it im making a new map.
The old one is dead to me.

MSAA + Forward Rendering RIP Editor
Anyone else run into this issue? I tried switching from TemporalAA to MSAA and now no matter what setting I put the editor to the meshes don't have their materials on them.
I'm using the Forward Rendering option, even when I unchecked and went back to deferred the level is all messed up even after restarting it.
velvet estuary
It probably doesnt help that I dont eject my USB's safely

I fixed the issue, I had to paste an old backup of the project file over my current one and it fixed the issue. ๐คท

@worn granite op, just going through this

@hard sage elaborate?
And this is more annoying: https://gyazo.com/c1bf26c19295c0646e1e6e483dd78f14

What's more annoying is perforce not validating files in place before transferring them.
And then having to upload them all again.
And even more so when I haven't deleted files.

@safe rose I'm just trying to lock off a camera so I don't accidentally move it/lose the composition
I know we can lock off scale, and I bounce from shot-cam to perspective cam to work, but I still accidentally move forward or up or down or rotate with the shot-cam frequently enough that its a problem :/

Anyone knows how to make a material emit it's own light? I know this was added in 4.13 or 4.14, not sure, but it's a rather new feature.

dynamic light?
emissive materials have contributed to baked lighting for a some time already
haven't heard you could do that dynamically
apparently LPV could support that at runtime
neither of those is exactly new thing though

@velvet estuary it's possible that a mesh referenced in the file is corrupted, but your college computer has a good version of that mesh in it's DDC, other machines don't hence they're crashing when loading. The stack trace you showed is it loading the mesh in preparation for storing it in the DDC.

hey all, I have a problem with sprinting. Only the server can sprint, clients can not. Any ideas?

so at every first time I open a project there is this blueprint with a compiler error, and I just need to open it and click compile to fix it. Every single time. Is this a known issue on 4.11?

yeah I remember that one
plush yew
is it possible to use 1 scene capture to somehow get an image of the scene with and without a blendable pp material at the same time?
main cobalt
Yo if I have 2 totally identical levels, build the lighting into one of them why does unreal think the other is totally unbuilt?
I have one version of a level that plays seguencer and one that is interactive
thin haven
because they are different levels, duh
cloud cobalt
@main cobalt Are those like, different level files ?
In that case yeah I can't see what you were expecting
main cobalt
Well when I build both I get the same issue
whichever wasn't built last is unbuilt in final packaging
They are practically identical levels
basically 100%
main cobalt
Basically I made the entire level
and then CtrlC ctrlV
one level always thinks its unbuilt
main cobalt
I've figured out a workaround for now, just getting the event player to execute console command to hide lighting build error

Inventory system in the market is shareware, so you must buy it to use

Does anyone know what the process or feature is called where basically a texture dynamically changes on a creature or whatnot. I remember the original UE4 teaser had an example of this.
velvet estuary
Thanks
plush yew
@tidal shore materials can be changed at runtime so that you can swap behaviors of your texture dynamically
velvet estuary
Hm, Is there any way to convert my sequence to the timeline? Would hate to have to do all that again
tidal shore
so is it just a simple shader effect then? I can't find the original "UE4 Trailer" where a guy is in a city and I believe his arm texture basically dynamically transforms into another, with things like bubble effects and whatnot. How is this achieved?

if you did it in sequencer I have never messed with that part of the editor yet

If I wanted a 10x10x10 3d grid of bools (or bits, really...anything I can evaluate to true/false), and each point in my grid oculd be read up to four times, is there anything I should think about on how to optimize it?
safe rose
@wet berry may I ask what this would be used for?
wet berry
I guess it doesn't have to be a 3d grid
Just 1000 bools that I can flip
It will be driving logic on how to draw a procedural mesh
Doesn't need to be 1000, may be less, but the idea is evaluting/altering a very large bool set
wet berry
Yeah, I may just stuff them in a 3darray
safe rose
Still don't really understand how the flipping is happening
wet berry
and see how it goes v0v
safe rose
Well, that's what gets done with all these voxel builders anyway
wet berry
Vectors are being used, but I can't quite figure out how to define the over/under on being drawn
so I have an array of structs defining vector locations + the draw/not draw value at each location, and logic drawing polygons according to that array of structs
but I'm kinda stuck on how to make them relate to one another for easy editing
As I've built each cube independently of every other cube
So I'd have duplicate vertices
And if I wanted to edit one vertex to allow the four cubes surrounding it to draw correctly to exclude that vertex, I'd need to walk the whole array
I was hoping to have a single array that I could maybe refer to by reference that would accurately populate the voxel array
When I instructed it to redraw
The alternatives are walking the array and searching for specific vertices
Or restructing the voxels to be aware of other voxels sharing a particular vertex
(the second one I don't want to do)
safe rose
Um
I don't know, I don't do minecraft stuff
I just know it gets done alot
There are some tutorials, free and paid for ue4 voxel stuff

Hello, im not sure whether this needs to be in programming or here, but while my c++ classes are in the folder and explorer, it doesnt show up in my editor and it's causing issues, I am using 4.14, any idea what is going on?
mighty vessel
You mean show up in the content browser?
pallid root
@keen ridge I had that same issue. The only way I could get C++ classes to show up in the Unreal Editor was by creating a new C++ project and migrating all the content over to it. It was less painful than I thought it would be to do the migration.
You can export your input controls from one project to XML and then reimport them into the new one
mighty vessel
wait does this mean he hasn't compiled the classes with the editor?
pallid root
I think he is talking about where it says C++ classes at the very bottom of the content browser
mighty vessel
there might be an easier solution, that is adding a class using File -> New C++ Class
that should set it up for use
pallid root
Maybe, I had an issue when trying to integrate C++ with the edtior where I made new actors in C++ but they didn't show up in the editor until I made the new project with the C++ template.
That's what you are supposed to do but it didn't work for me
I thought it might have been because I migrated from v4.11 and worked my way up through v4.14
keen ridge
i think i'll just stick to 4.13 then : /
actually.... looks like theres somehow a compile error in the project
pallid root
@keen ridge when I had that issue, I was not able to make any successful builds either. It kept complaining about missing namespaces in the default files that the editor had created.
keen ridge
fixed it, it appeared to be a build issue for some odd reason

I've been kind of lost since I started learning UE4 a few days ago. I see a lot of possibilities and great uses for my future 2D game projects, however, the studying material I've found is rather shallow in programming terms. Most deal with Blueprint stuff and those who actually deal with C++ programming and program design are 3D related, which are not quite what I want.
I would really appreciate some light shed in how and where I could learn UE4 2D game development and design patterns.

anyone know how to get the editor not to minimize when the vr preview is launched?

I saw a discussion about that the other day. Apparently there is a large performance impact which is why it is auto minimized.
I think I also saw that there was a setting to disable it but I don't remember where it was. I was wondering that same thing though since I wanted to be able to see logs easily.
sour shard
yeah well its a pain to debug with the log being minimized every restart
if it could leave up the log i wouldnt care if it minimized it

Yeah, or I'd like to even see the blueprint graphs for certain stuff. I ended up adding a 3rd person character for testing things that are not VR specific.

I have my game setup so when I shoot at enemies I do a line trace by channel and at the impact point on the mesh it plays a sprite and deals damage. I'd like to be able to do things like extra damage for a head shot. Do I have to do a second line trace that ignores the mesh and only sees the bone that is hit? Right now the single trace doesn't report back any bones being hit if I have it set to block all.
pallid root
This works how I have it now. I guess my concern is that I have to do two line traces for each shot fired. Is there some way to get all the items a intercepts with in a single pass?

well, they said the it doesnt support wii u and there is a game coming out to it

Go with Unity. They have a complete Suite on the Nintendo DevNet
plush yew
its kinda relative i think, because unity is not running on c++ and runs on nintendo 3ds ( actually only on new nintendo 3ds )
and c++ is way faster
cursive dirge
unity is c/c++
only scripting is C# etc
and scripting isn't the part that's heavy on your game, the game engine tech handles all the heavy lifting
tall pendant
plus it doesnt matter if its c++ or whatever. If the underlaying Tech doesnt support a platform you dont have a lot of options.
plush yew
yeah, you're right
thanks guys, i'll do a little more research on the topic ask on the dev forums too
maybe i'll just drop the 3ds idea

Anyone know where I can find answers for these questions: Why does UE4 create another one of my blueprint car in my camera view instead of on the pawn class i selected? Why can't i make my vehicle move even after phAT and animation and the wheeledvehicle blueprint has been correctly (i believe) set up after both youtube guide and "Vehicle user guide" on ue4 page? Sorry for just jumping right in with a question like this.. Grateful for all answers and help I may get. Note: I've looked at world settings and project settings but can't find a problem there.

@burnt drum I've used it before... isn't it stopped being supported because Lionhead Studios shut down?
I had trouble getting LPV working for large scale scenes, it seems like I couldn't increase the scale of the volume so distant objects kept becoming unlit from LPV
burnt drum
@proper quiver you can. you can increase the 'size' but I woudln't recommend spamming it as it increases performance cost
proper quiver
it's hard to describe, I'm making a sim-city like game and wanted the LPV to cover the whole viewable region
proper quiver
however, the LPV works when I'm hovering just over the city
when I'm zoomed out it doesn't work at all
burnt drum
right i see what u mean
proper quiver
I had to "cheat" it by using FOV zoom
burnt drum
we have that issue as well.. since we are doing FPS / RTS
in our RTS view the LPV just gets disabled
burnt drum
perhaps if you can find a quality scale.. perhaps you can increase the size dramatically but reduce the accuracy
that could work
LPV seems to be a bit of an old tech, but I still find it very relevant and hassle free. i do hope Epic continues to maintain it as a dynamic GI alternative
proper quiver
it's weird, I tried increasing the scale but it seems to max out after a certain point
like, the volume just would not grow bigger
the scale seemd absolute, too
proper quiver
right, I meant size, it's been a while
proper quiver
yeah I hope they keep working on it because I really like what it brings for real time lights
burnt drum
i think in your case it would require some engine modification
yeah.. i do hope they push it further
perhaps if more ppl use it.. they might

I am trying to switch between cursor icons by creating a widget with my cursor texture and selecting that as my default cursor icon in the editor preferences, then in game I cast to that widget to switch my cursor icon to say a hand icon, it works except when I click it goes back to being the default widget again. Anyone know why it does this?
I use this to set it - https://gyazo.com/89823781f2c584ea1d188e96366e9488

Indeed and I selected that widget as the cursor in the editor preferences

Because when I replace my cursor, I go to the User Interface section of the project settings and under the Cursor settings there are two classes that I had to replace with my cursor widget to get my cursor to stick.
One was the general and the other was called something-trigger iirc

Let me check that again, I know I had to set more than one to get it to show when it held the click
Out of curiosity I set them all to use the same widget and it still goes back to default one after right or left mouse click
default texture that is
next kite
Close enough LOL it was the default cursor setting in the controller. I hadn't changed it before and i guess when it doesnt match what is in the project settings it overrides the brush texture i set when I click. All I know is that it works now. Cheers!

Hey!
How you automate import of assets into UE4? In Unity there is AssetPostprocessor class. Is there something similar in UE4?
Or do you do all this always by hand?
buoyant mesa
Propably there is, but so far I have imported thm by drag and drop
plush yew
Half of the problem would be if by reloading asset it would reload it from the same path it was imported, but instead it seems it just resets all metadata that was set on import and still uses uasset data, just this time with new metadata settings.

it is only viewport problem it seems in game it doesn't happen until you mouse over viewport, we came in conclusion it gotta be old gpu drivers or something like that. Gonna try another pc tomorrow thanks for the help ๐

this is not a problem with SourceTree or Bitbucket, it's just the way git works

Ok, thanks!

there is nothing you can do for map files and/or models and graphics
but you could move from blueprints to c++, source code is perfectly mergeable meaning if you change one line, git saves only that one line change instead of the whole file

yeah, i'm on vr and the actor spawns in a weird place. Must have something to do with where the location of the player is being counted as

@trail saddle do you know how to make the object face the player?

try setting the rotation of the player to the object and setting the Y value to negative
If you want the object to always face the player, put it in the tick.

@plush yew you could increase gravity once the object hits a flat surface such as the ground (dertermined by racetracing downwards)
than after say 1sec or less you turn physics off on the object making it static until player or AI interaction is executed on the object once again
also helps with performance by doing that

Anyone got an idea how to lerp two Red channels (two roughness channels) and an alpha? I'm getting an error. They are both world aligned textures so that might be the case? Or maybe I should somehow append both of those red channels to RGB before the lerp?
@bitter edge This might help: https://www.youtube.com/watch?v=O3zeklh9mSg
bitter edge
@spice scarab Sorry I meant character animations not camera. I've gone through the basic tutorials for sequencer and I can easily animate characters, but, smooth transition between aniamtions is aluding me. I keep looking at the documentation and googling...I must be missing something.
spice scarab
@bitter edge Oh.. I thought this link had camera plus two animations. But I'm not sure if they are "smooth enough" for what you are looking for? I kinda thought the smoothness of animations and how they transition from one to the other comes from how the animations were made and not from the sequencer. But I might as well have misunderstood the question! : )
bitter edge
@spice scarab The two animations have no blending between them so they "pop" from one to the other.
I know I can smoothly blend animations in blueprints, but I was woundering if sequencer had a way of handling it.
@spice scarab and if seuencer dosnt handle blending then will it understand and use blends I create in the animation BP
@spice scarab I'm sure other people have had this issue before I just cant seem to find any info on it.
spice scarab
@bitter edge Ok now I understand but I havent tried animation blends with sequencer. I've only been using camera myself. But they should work I guess? Otherwise it would be pretty hard to make a cinematic within the game where a character would run from point A to point B while shooting and dodging bullets or something. Because that would require blends, right?
bitter edge
@spice scarab I'm sure theres a proper way to do it.
spice scarab
Maybe the "Sequencer" pack from the Learn tab would have the required knowledge inside. Maybe you would just have to reverse-engineer the scene.
I'm not sure because I haven't tried it yet.
bitter edge
@spice scarab Thats a solid idea

has anyone used it? Is it useable in its current state?
bitter edge
@spice scarab So, I've been digging through shot after shot within the content example for sequencer, and epic isnt using mulitple animations per shot. They are are doing 1 animation per shot, per character...
spice scarab
@bitter edge Damn. :E
bitter edge
@spice scarab My thoughts exactly
spice scarab
@plush yew Yea I think I made an AI that used it and it worked fine. But it was just a deer that was searching for places to hide and run behind if it saw me. But I'm not a pro so don't take my word for it. Also I had a facepalm-moment when I updated the patch and I forgot to re-tick that experimental box and I was wondering why my AI wasn't working.

Guys, where can i ask an specific copyrigth movie music adaptation for my game?
question*
xd
spice scarab
@viscid dirge I don't know. : ) But I guess the easiest way would be to ask copyrights from individual artists etc. You might save some pennies. At least if a band makes a cover of a song for an album the easiest way for them to ask if it's ok is to contact the person who made the song.
I told two seperate things like they were one but yea...
viscid dirge
But for example, could i include a parody version of star wars intro? Or that is considered copyrigth infringing ?
Copyrigth is so messy in some cases ๐ฆ
spice scarab
I think the movie critics of the whole damn internet have been fighting over those things because I think it says in law that you can have 17 seconds of uninterrupted "copying" if it's not total copy but a part of some other material which is made by you. For example critic talking on top of a scene or showing a clip of a scene to make a point about something. Or some guys watching TV and something that has copyrights is playing on their TV... 17 second rule should apply. But I'm not sure.
viscid dirge
17 seconds sounds fine ๐
spice scarab
Basically best way is to make everything you can by yourself or get connected with the people who know more about the things you don't. Or just ask the particular person/company involved.
spice scarab
But the first way (making everything by yourself and asking help of others) is best because then you can be sure you aren't steppin' on anyones toes.
But yea... Star Wars theme.. I think it's ok if you have your own content on top of the music and the music aint too long.
viscid dirge
Its just the intro of the game ๐
I always try to add my own content, but star wars intro is too strong ๐
bitter edge
@spice scarab I can always create smooth blends in the animation BP for a charater and then just call specific animations within sequencer, but its a pain. O well.
spice scarab
But I think you should ask some composer to maybe make a parody version of it (that has some variance in the melody) or ask for a license. I just read this. :E
@bitter edge Lets hope there's a different way (and that our discussion brought some attention to it) but yea.. I wish you good luck! : )

I don't really get Epic stance on Temporal AA
they clearly know it's bad in regads of the ghosting
on forward rendering stream Daniel said it's not as bad on desktop but his example scenario why it's not as bad didn't make any sense
I think he said something about being able to render high frame rates on desktop so temporal sampling between two frames is fast or something like that
but you render 90 fps on VR...
thing is, the faster things move, the worse ue4's TAA becomes
it just can't keep up

one of my models got corrupted
but I removed it and that did the trick, thanks for the log info @worn granite
worn granite
Yeah, it's always eaiser to dig through and find what's wrong than to reinstall and hope for the best.
Another thing, if you build your game's editor and you have the symbols installed you can debug it rather than launch it normally. That way when bad things happen you can see the call stack and such.
Just right click the project in the solution explorer and you can debug it.
zinc bison
has anyone ever done input stuff in C++, and also BP? it seems like the C++ overwrites the BP input event
I cant find anything on google about how to do it

@burnt drum @cursive dirge There is a flag AA_DYNAMIC_ANTIGHOST here https://github.com/EpicGames/UnrealEngine/blob/55c9f3ba0010e2e483d49a4cd378f36a46601fad/Engine/Shaders/PostProcessTemporalAA.usf#L372
if you set that to 1. Most of the ghosting disappears. At least it was that way for our project. And as far as I know this should be improved even further in 4.15. But it worked great for us even in 4.14.
cursive dirge
I know the flag
it doesn't cure the whole problem
you can get rid of the bright part on the ghosting with that
but you fast moving object will still have dark allaround mess following it around
I guess some people might not notice it if the background isn't that different from the moving object though
it also still blurs everything ๐
@zealous cloak ^
I haven't tested that on 4.14 but I think I did a lot of testing on 4.13
zealous cloak
oh yeah, the mess is stil there.. but you don't get frame by frame ghosts of the object.
cursive dirge
I also tested that SMAA fork someone did
zealous cloak
it looks more like a blur in this case.
zealous cloak
how is that SMAA fork ? it is in my todo list to merge those changes into our engine version.
cursive dirge
it didn't work for my use case at all
plus it looked crappier than FXAA on my extreme test
TAA looks amazing on the distance, it's just he nearby things that get wonky as pixels move too much between frames
zealous cloak
oh ouch.. I was quite hopeful about that fork..
what I hate about TAA is that.. when you do some animation in material. TAA blurs that like crazy since there is no motion vectors for that.
cursive dirge
I hope they'll make forward + msaa usable for desktop
that's all I want really
but they seem to want to keep it VR focused
@zealous cloak https://www.youtube.com/watch?v=-TpBF0iTwsY
that doesn't have that dynamic flag set for TAA
I only learned about it after I had made that vid
I also put the worst case scenario for TAA there (huge contrast for the moving object)
I actually have that kind of situation on my real project too as chrome bumpers ghost really badly
but that dynamic flag would help a bit there
zealous cloak
oh yeah TAA looks very bad in that case.. we also have driving on asphalt scenerio in our game. TAA fails very bad for that.
cursive dirge
yeah, anything where you get big contrast between moving object and camera followed object will fail
besides, I want to have VR support
so I really need that forward support to work
I asked on the rendering stream if you can mix VR forward and deferred but answer was no (like to be able to change that within the same executable)
reason was that it would double shader compilation time (which I would have been ok with)
so, at this movment, if you need AA, VR and desktop modes all on your game, going all forward seems to be the only solution
it's just really bare bones atm
you can't even get shadows for anything but stationary lights and need to have static light building enabled on your project for that
zealous cloak
oh, i understand. I never tried the forward renderer before.
@cursive dirge Did you see this commit ? I wonder if anti ghosting is much better in 4.15.
cursive dirge
oh
sounds nice at least
doesn't help with the VR issue though
(you can't ship with forward + deferred both on same project)
too bad epic doesn't do game that have optional VR mode :p
they would solve that if they needed it
zealous cloak
heheh ๐ yeah.. kind of sucks that epic does whatever they need first ๐
cursive dirge
it makes sense from their viewpoint of course
zealous cloak
well, still much better than Unity. who does features that are always half complete, or only enough for their demos.
cursive dirge
but it seems like they haven't even thought about people who do games that have VR as optional mode
zealous cloak
about compiling shaders for forward and deferred. I can kind of understand them being afraid to introduce that change.
I mean, compiling shaders takes a loong time usually.
I wish shader compilation would be faster.. so that they could add forrward+Deferred support, and also more than just the simple Material Quality Switch node into materials. But like static defines per material. It would be awesome.
cursive dirge
yeah, that's what Daniel said on stream (that it takes forever already and they don't want to double the time)
@fiery harbor have you tried TAA improvements on 4.15?
you were using master, right?
fiery harbor
yeah, but haven't updated master to after that merge happened
so couldnt test it yet
I can only say that TAA looks horrible in VR
fiery harbor
once SSAO is supported in the forward render I won't need to care about TAA any more ๐
cursive dirge
shadows are done in deferred, they make artifacts on msaa edges and you only get dynamic shadows on forward if you have stationary lights
you also have to have static lighting enabled on your project for that
fiery harbor
no they added support for dynamic movable shadows now
cursive dirge
on 4.15?
cursive dirge
oh
that's cool
when he was on the stream, he said he couldn't tell when that'll happen
fiery harbor
cursive dirge
I haven't actually seen then but Daniel showed them on the stream, I don't work with forward shading atm
I've only tested forward on 4.13 and 4.14 previews
fiery harbor
ok
cursive dirge
@fiery harbor https://www.youtube.com/watch?v=F4Z1V9Qe7F4&t=1384
oh well, discord just doesn't want to embed that
link should still work
fiery harbor
well he said its the biggest problem with forward
then I wonder why he first added support for movable shadows is that was less of a problem ๐
maybe they fixed the shadowing stuff already before without me noticing
cursive dirge
wonder when we'll get 4.15 previews
they targeted it till end of this year but I doubt it'll happen anymore
or they'd need to rush it already
fiery harbor
probably next week
unreal sonnet
Can anyone recommend a "let's make a guy in blender, rig him to a skeleton, and give him a simple animBP" tutorial?
plush yew
that sounds like you might be better off with three seperate tutorials
unreal sonnet
I feel like there's a bit of a disconnect in the tutorials I've gone through, though, for that stuff. I've either found tutorials where you just make the guy and import him to the editor and I've done tutorials where you retarget the skeleton... but I haven't seen anything that shows the in-between stuff (e.g. "here's how you connect the model to the skeleton so that you can actually do the retargeting part")
idk though, I am stupid
plush yew
nah, its not stupid to still be learning stuff, we all have to go through it ๐
if you want to see how to make a skeleton, then use this
This one right there, Basics of Character Rigging is where I learned how to make skeletons for models
Once you're far enough along that you can make your own skeletons and animations for models, you shouldn't have too much difficulting exporting the Epic Mannequin skeleton and rigging that to your models so you can share animations
brave mason
Houston, we have a problem!!
We've got the engine crashing on project load (4.14.1) when it hits 93% any time we make changes to a few assets
we can perforce back to a working copy, but then if we modify assets in that game it crashes on load again
safe rose
@brave mason I have had the same issues since 14.0
brave mason
oh noes!!!
safe rose
Compiling, Saving
usually when there are structs involved
in that bluepritn
blueprint
But yeah, please report on Answerhub
brave mason
we have
brave mason
I can't even work on my project atm
safe rose
just keep posting until something happens
brave mason
we've got areply from epic
safe rose
it's pretty rediculous
brave mason
I might e-mail a contact at epic
are you having problems with your project loading at all?
safe rose
But today, surprisingly, I didn't get a single crash
but over the past wek
week
I had roughly 30 crashes PER DAY
I am not even joking
brave mason
I can't even get my engine to load
safe rose
It's stupid because
As soon as I load it back up
I do the exact same thing and it compiles/saves just fine
that's when I submit my commit obviously
It seemed like a 30% chance to get rekt
@brave mason you delete intermediate?
build
brave mason
yes
safe rose
and any other junks folders
brave mason
I even zipped up the project
moved it
unzipped
edited the player pawn
saved
crash on load
safe rose
Sounds worse than me
And I thought I had it bad
It made what could have taken a few days, over a week
brave mason
I got it working, felt positive, made a bunch of updates, and then it wouldn't load again
can you replicate the crashing?
