Fog + Groom sorting #44

Closed vfxbyjohn closed 2 years ago

vfxbyjohn commented 2 years ago

Hey,

Just wondering if you or anyone else has ever tried to render groom with a fog volume? I'm currently trying todo just that and have noticed that the groom will always render in-front of the volume. I've tried using the console variable r.HairStrands.ComposeAfterTranslucency 0 and while that works for materials like glass, it dosen't affect the vdb. fog_groom_01

I'm assuming this is related to how the volume material is setup but I'm unsure if its something that can be solved?

This is using the VdbMaterialActor, if I switch to the VdbPrincipledActor it sorts correctly! But ideally I'd like to be able to use the Material Actor for game play :)

Same issue as #32

Yes, sadly I'm aware of this issue and don't think there's a proper solution to the problem due to limited extensibility from a plugin, sorry.

Ah thanks all, sorry I didn't see the previous post, I'll close out this one
