Will flex support softbodies for characters ?(skeletal mesh) for like DOA like physcs(breast jiggles)

I think it could be used for that. We haven't integrated it in that way yet, but I think it's possible in principle.

So no matter what I do, I cannot build the VXGI branch at all... am I missing something obvious?

I think some files were overwritten by the Setup utility. Did you switch to the VXGI branch before or after running Setup.bat? The way I do this is
(1) git clone the default release branch
(2) run setup.bat;
(3) git branch VXGI origin/VXGI
(4) git checkout VXGI
(5) generate project files
(6) build

I just have been in the same situation.
I'm not using GIT and I have simply extracted over my installation folder the zip that I download from the github page. This made me able to compile the engine. However I now get a crash at startup, I have added my log below. I'm not sure if the warning about the texture pool being at 0 is normal ?

Any help is appreciated.

You have to rebuild your ShaderCompileWorker. Sorry about that, there is a bug in the dependency for that module, and you have to build it separately. I just committed a bunch of changes, including new ShaderCompileWorker binaries, so you shouldn't be seeing that particular problem in the future.

I also submitted the SciFiHallway scene with VXGI, as we showed at GDC.

Using git, or just a zip file? If you are working through zip files, you'll have to do the process over again, although really you could just grab the Engine folder from the new zip and drop it on the other one.

If you use git and have a VXGI branch already working, all you should have to do is "git pull origin VXGI"

I use Git! Ty for explaining mate, that'll save tons of time. Can't wait to see the new fixes!

Commits to VXGI branch are in. Please let me know if something is broken. I tested the build, but couldn't test the runtime because I'm on a laptop right now.

Any timeline regarding fluid rendering? I'm also interested in any information on what is involved for the integration.
I see the demo uses GL shaders. Anyone had a go at anything? I'm clueless with shaders, wouldn't know where to begin porting.

I know that the engineer working on the fluid rendering had started on it, then was sidetracked on projects for GDC and for customer support, so he was delayed a few weeks. I expect we'll see something by the end of this month. The GL shaders from the demo have to be ported to Epic's RHI system, which I think uses DX-like HLSL. I'm not a rendering expert either, although I'm trying to come up to speed on it. Shouldn't be a huge deal once he gets back on it.

Pitty, VXGI stopped working on my GPU... (650 Ti)

Fatal error: [File:U:\UE\UE4VXGI\Engine\Source\Runtime\Windows\D3D11RHI\Private\Windows\GI_InterfaceD3D11.cpp] [Line: 1950]
VXGI Error: FLOAT16 emittanceFormat is not supported by the current GPU. (GI_Base.cpp, 351)

.....

And found the setting set made it work..

[VXGI]
bVxgiStoreEmittanceInFP16=false

Hey Mikand, any news on your waveworks?

**Mikand79** · 03-13-2015, 06:59 AM

It's not mine

Last check: I didn't do wrong, it just doesn't like to work together. Though I've not yet reported that and the other two issues on github (one missing debug library, one guard check needed for shipping builds).

Now the branch was updated so I gonna test mergin once more before I do.

**Gandosh** · 03-13-2015, 07:06 AM

oh alright haha. By the way that last build of vxgi is 4.7 right?

**Mikand79** · 03-13-2015, 07:09 AM

Alas its not

Ha perfect, I got the editor running. I will be able to play with it now.

Thanks!
Finally can load SciFiHallway, GPU(GTX Titan).
