 - [ ] studio models: fix lighting: should have white texture instead of lightmap OR we could write nearest surface lightmap coords to fake light
 
 # Planned
+- [ ] rtx: transparency layering issue, possible approaches:
+	- [ ]  trace a special transparent-only ray separately from opaque. This can at least be used to remove black texture areas
 - [ ] rtx: sky light/emissive skybox:
 	- [ ] consider baking it into a single (or a few localized) kusok that has one entry in light cluster
 	- [ ] just ignore sky surfaces and treat not hitting anything as hitting sky. importance-sample by sun direction
