IRAY Decals with weird bright seams

boronk_223d50468c

Hello,

 

I have some strange issues with iray decals that happen once I use spotlights (independend of mode) and I zoom out so that the decal is very small w.r.t. to the image size. In this case, they get a bit of wrong rending of the transparency making them bright seams at the place where the transparency is not 100% but a value in between. Am I the only seeing that? It goes away once i move the camera closer.

Iray decals are broken in 4.21+, so it's probably that.

The same issue was with 4.20 .. I upgraded to 4.21 today because I hoped it would be fixed.. but what is broken and how is the alternative?
