Hey, does anyone know how to use using an Emmissive Plane still emit light when its invisible? I’m using Area Lights for windows, but I don’t want it to block the exterior.
HI… i’m trying to download the engine with VXGI in github
https://github.com/NvPhysX/UnrealEngine/tree/VXGI-4.14
but resuming download is not supported and it doesn’t show me the zip file size…
sadly i’m on a very unstable network…
does anyone know the zip file size or any other sources to download this?
thanks in advance…
VXGI-4.14 is 905.4 MB
VXGI-4.15 is the latest version and is 911.4 MB
I doubt there are any other legit downloads for this but you could use the git command line tools or github desktop to download it.
Also note that when you start the next step by running setup.bat multiple more gigabytes will be downloaded (approx 4GB off the top of my head)
Download using git will allow you to ‘resume’ download as you download lots of files as opposed to one big zip file.
You can probably size down the size of the actual VXGI build, but keep in mind that in 4.15 and beyond there’s a graphic issue involving visual effects that is quite noticeable.
It might come from the 4.15 Texture Streaming overhaul, i don’t know, but it’s a real blocker for me.
Fun fact. Git actualyl does not allow to resume anything. You either can download in single batch or not. That is when you are cloning repo.
Thanks man…
Thanks for the tip… i’m assuming 4.14 would be fine, Right?
sorry, i’m new to Git… what is “cloning” in github? if i do the cloning in my git desktop, it will clone/download it to my computer?
4.14 is the most stable yes
awesome… thanks.
hi i try to build 4.14 and 4.15 with vxgi from github going with instructions but get insane numbers or errors
am i missing something basic ? wrong environment variables ?
If you’re grabbing the VXGI build straight from Github, the workflow is straightforward:
-unzip
-run setup.bat
-run Generate project files
-open project files in Visual Studio
-select the ‘UE4’ project below ‘engine’ in the Solution viewer on the right, right click->build.
It has to work really, i did it time and time again ^^
edit: looking at your error, are you sure Visual Studio is properly installed? have you tried compiling some random C++?
Looks like there’s issues with the standard library, yet it’s something rather basic 
i did a full reinstall of VS 2015 same thing
made blank project >> MFC application
and get same build errors …
here are options i have installed in VS
will try to redownload vs2015 …
ok did a fresh install of windows and VS2015 today redownloaded eveything again
now Setup.bat goes ok downloads all it needs.
runing GenerateProjectFiles.bat gets me errors -showing last 2

ok did clean temp folder and compileing now
Does anyone know why particles with translucent materials donot render in VXGI-4.15.?
It’s actually a wider issue than that. Most VFX, sprite smokes, water splashe etc… don’t work. I guess it comes from the full rework of the texture streaming pipeline from 4.14 to 4.15 and beyond which corrupted the hooks VXGI used to the rendering pipeline.
Those stuffs aside, it’s working, i’ll therefore assume there some adjustements to make but it requires to understand both VXGI integration and the engine.
Well, i Compiled the 4.15, Branch of VXGi, Standalone it works, but Truelly when i Convert a Project of Myself, for it its just Crappy Compatible,
The Plugins all are not Compatible i get everytime an Error,
I Cant Open any Map, Everytime an Fatal Error and Instant Crash ,
and im Sure that im not Gonna Build my Map again Completly,
So whats the Best Way to Use VXGI in an Already Exist Project?
It can be that its Incomaptible with so Much.
And i Speak just from 4.15
Want my 4.15 Project in 4.15 VXGI,
So Pretty the Same Version, but i tryt now to
Switch it to VXGI 4.15 (with rightclick)
Open a Copy on the VXGI Launcher,
just Copy the Content Older into it
Nothing works, Everytime i get an Instant Fatal Error, when im Load a Map,Open my Character Etc
That Sucks, and that Happends to an Project i created in Normal Ue4.15.
Any Ideas?
If you want to use VXGI for your project, i’ll suggest using the 4.14.3 branch for now.
Well, Can i Convert my 4.15 Normal Ue4 Project to 4.14 vxgi whitout Big Problems?
Because i got too much Fatal Error.
hi all i had luck compiling ue with vxgi did some scenes but now when i want to open it i get
VXGI Error: Invalid state: finalizeVoxelization(…) has to complete successfully at least once before cone tracing
google does not help on this
-edit
well did restore scene from saved folder works fine now …
