There is an issue with some model textures not rendering correctly during rendering. I have tried flipping the normals in the model, but it doesn’t seem to have any effect.
Hi I’m here because I’m having the same issue, to clarify not just with glass. Making it two sided hasn’t helped. Spent hours trying everything I could.
It’s something to do with the importing from Sketchup. I managed to remake a couple of groups (cabinet doors), resync, and cause it to come up on more pieces like this, but not reliably.
I’ve covered my whole model with the same Ash woodgrain material in this image to give the full effect of whatever is going on.
Thanks
When importing the model, did it ask for the path to the materials ?.
Was it a udatasmith file ?.
Why do some materials turn black when path tracer is ON? (epicgames.com)
