Is there a way to open up projects worked on in 4.7.6 in the VXGI build (or move the VXGI build to 4.7.6)? It's only compiling the engine as 4.7.4 for me after merging the branches, and while it loads all the individual assets, the map file itself crashes the editor and I suspect it's the version mismatch (happens when migrating the project to another machine with a clean 4.7.4 build as well).Last edited by Zero-Night; 05-14-2015, 01:51 AM.

Would really like to see some examples of how it might look if someone would try it for me. I'm mainly interested in the quality of the reflections.Originally posted by darthviper107 View PostSince the GI is already tracing bounces, it uses that for reflections. But the detail won't be as good as other reflection options since the quality is controlled by the voxel density.

That being said, they bring detail to the scene, but are not high resolution themselves. They work poorly with materials that are smoother than 0.2 roughness, and are generally poor on a perfectly flat metal surface, such as a metal floor without normal mapping.
Well it may be no problem for static objects but when objects move, this is anotehr story, especially when the moving objects are dynamic GI sources using two bounces when they move. It is a common problem for many dynamic GI proposed solutions even the one I stumbled on for Cryengine using two bounces when objects move and cast reflections (here it is even more complicated since the moving objects are dynamic GI sources using two bounces when they move). Here I highlighted that way back in my comment:

and I hope VXGI will find great solution so we won't encounter such ugly pixel on reflections of moving objects
Also about about single bounce specular: VXGI did encounter some problems with some indirect specular coming from indirectly lit areas having objects not rendered in screen-space since it uses only one bounce, I really hope now that they will solve this with their multi-bounce solution.

So I compiled a build of VXGI for 4.7.6 and while it seems to have identical results as the 4.7.4 build in the test scenes included, I've been having some difficulty getting it to display properly in my own scene. Specifically, I've been running into a lot of light bleeding, and the reflections don't seem to work. I know it's probably a setting I haven't set properly, so figured I would just ask here if there were any obvious solutions.

Hello friends,
Very sorry for the long delay and my absence from the forum lately, things have been busy with travel, etc. I'm happy to announce that the first-pass integration of HairWorks is up on Github now, https://github.com/NvPhysX/UnrealEngine/tree/HairWorks. There are plenty of issues yet to be resolved, we're not happy with the shadows and aliasing, and there are other rendering artifacts here and there. Also, this first pass is implemented using Blueprints for managing and tuning the hair assets, and we expect this will change in the near future, so please don't expect any assets you create with this first-pass integration to be future-proof. Be sure to plug in an Xbox controller when running the HairWorks map, the controls are blueprinted to the controller buttons right now; we'll create a keyboard map in a future pass.
Thanks,
Mike
