Thanks a lot burnin! Can you maybe just mention your GPU generation? :)burnin wrote:those 3 issues confirmed here on nvidia
The first material has a bum scale of 4mm, the second of 3,5cm (!). If you change the first one to such a big value too, you end up with the same artefacts.Zalevskiy wrote:interesting situation with denim material:

Gamma is ignored for normal maps on CPU, have implemented this behaviour for GPU as well.thesquirell wrote:Not sure if it's a bug, could also be a feature thing, but when using Normal map with GPU rendering, default gamma value of 2.2000 gives funky results, while in CPU it renders "normally". Changing the value to 1.0 gives "normal" results, but it seems a bit weaker then the CPU Normals. So, if you're having funky problems, watch out for gamma. Also, to point out, the default value for gamma in the Cindigo (Cinema4D exporter) is 1.0, so, this won't happen if you're using the exporter, but when testing/creating a material from the default scene, it could cause confusion. Or, it's a bug.
@Zalevskiy: Товарищ, check your gamma.

Please download the material if it is technically possible with the GPU, thanks
It's a problem with strong bump mapping on GPU - the normal was not clamped. Fixed for next release.Zalevskiy wrote:@Zom-B thank you very much for your help with the reporting!
