@MoritzGrebe can you share a simple file with material and decal where the decal does not work in Raytraced?
there still seems to be an issue, i have noticed it a few times, it somehow gets stuck and i have to switch to shaded and restart raytraced which usually works eventually but it often hick ups starts rendering for 5 seconds then it reinitiates rendering and the decals disappear. after switching to shaded and start raytracing it works⌠talking about viewport. using v7 latest
The problem is still present in V8. Workaround. Have two identical copies of the decal applied to the object (one is concealed by the other). Fart with the objectâs material roughness. Then toggle the âhiddenâ decal either on or off. Then Raytrace. Note: the decal is applied directly, not via the material as others have attempted. This method worked 4 times in succession.
The method noted immediately above has worked at least 100 times now. However, it requires that the material have something such as roughness or glossiness to adjust. If the material is plaster, then no luck.
