Author Topic: Normal looks inverted when going on Iray Render  (Read 3049 times)

belga-22

Hi,.
I have a strange bug on my 2 last models. The normal look fine on the viewer, but When I go on Iray, it looks inverted -y. I never had this issue before. If I can have some help, it will be great :) The model looks fine in Marmoset toolbag 3 and Unreal engine 4 too.

It looks like your normal map is inverted in Iray, could you please attach a log file?

I have same issues with multiple projects. Everything was baked in painter. Painting viewport is great, when switching to iRay for money shots, normals look inverted in some areas. Looking forward to the fix. Thanks  much!
