@louhikarme yes you are right! I do the cutout with boolean, but separate object’s with array modifier aren’t more work and the benefit to have influence at the texture will surely help a lot. I try to test all this great Ideas today! Thank you a lot!
@spikeyxxx thanks for the link! I looked some procedural wood shaders before but they are very complex. I have to study the blend modes and how to mix nodes the right way. I like to experiment with the nodes but if there is not enought knowledge, it takes to long 🙂
