Hello . Any news on hairworks and 4.7 ?
GDC 2015 slides for The Tomorrow Children tech have been released:
://fumufumu.q-games/archives/TheTechnologyOfTomorrowsChildrenFinal.pdf
Hopefully will give you guys some ideas for VXGI.
I am amazed that they are able to achieve both anisotropic voxels and 16 cones per bounce on the ps4.
i testing same material with reflection and refraction and realized a few things. The only thing is reflective is direct light and difuse color generated by direct light, the other things like a gi, refraction, emisse nothing is reflected. The refraction is very cool, refracted every thing like reflection, emisse, gi and other, but when you changed the material mode to translucent all channels is disable except refraction and opacity. the other channels like a base color, metalic, roughness and others dont work.
Thank you, well: the issues Iām having is that most of the specular settings never seem to quite affect the game world. Whenever I tweak something I donāt see any changes. Sometimes I think VXGI isnāt even getting information about specularity
emissive not emisse
i saw your video and i didnt see any vxgi efect i thing you not enable
i confused about refraction, the refraction dont show emissive
You can check very closely at 3:10 from onwards the bounces. Specially in the staircases roof near the end.
Sorry for the delays. I am working on a VXGI update right now, I should be pushing that to Github later today. HairWorks might make it by the end of the month, they are still dealing with rendering issues related to aliasing and transparency. Regarding 4.7, Iāve started on it, but I am still studying the changes.
Ty for that notice! One question thoā
For updating the VXGI branch, I have to download the whole branch again and then recompile it? Or running the setup.bat to get the files and recompile would be enough?
Does mean you guys have resolved most of those issues - i.e. point light shadows, particles, multibounce, etc?
patch will should fix the shadow issues. Still working on the others. Multi-bounce will probably take a while, not sure about particles.
Using git, or just a zip file? If you are working through zip files, youāll 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 āgit pull origin VXGIā
@.
Will flex support softbodies for characters ?(skeletal mesh) for like DOA like physcs(breast jiggles)
I think it could be used for that. We havenāt integrated it in that way yet, but I think itās possible in principle.
I just have been in the same situation.
Iām not using GIT and I have simply extracted over my installation folder the zip that I download from the github page. made me able to compile the engine. However I now get a crash at startup, I have added my log below. Iām 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 shouldnāt be seeing that particular problem in the future.
I also submitted the SciFiHallway scene with VXGI, as we showed at GDC.
I use Git! Ty for explaining mate, thatāll save tons of time. Canāt 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 couldnāt test the runtime because Iām on a laptop right now.
