Layering Dirt Nodes

Fri Apr 14, 2023 11:24 pm

Hello, today I've been working on texturing and been messing around with a lot of dirt nodes; multiplying, adding and layering them. In the middle of work, I realized that when I connected a dirt node map it made another map disappear from the live viewer. The maps look fine when soloed but once they're attached to the material mask something goes wrong and it doesn't display them properly. so now I wonder if it's a bug, there's a limit to what I can do in octane, on my PC or something else. When I connect a diffuse layer to the group, another part of the other layer disappears. The same thing kept happening with the composite material and masks there. It might be worth mentioning that the same thing occurred when I tried to mix it with Curvature nodes.

IIRC there is a limit of 3 dirt nodes per material but it looks like you’re only using two here so it’s probably not that?

no actually, you might be right. in this project I have 4 dirt nodes that are multiplied for one material layer and then one additional for another. so when I want to connect the 5th one to the material things seem to break, so the limit might be 4 or 3 and I'm just not really seeing the difference when losing one of the nodes. A similar unexpected result happens when instead of a dirt node I use a curvature node. I wonder if that limit could be lifted. alternatively, I could bake the dirt node and although it's a bit troublesome when I'd prefer to adjust things on the fly, it might be the only choice.

edit: also the composite material didn't seem to make any difference so I guess the sub-materials don't really fix the limit either unfortunately.

edit 2: plugged all the nodes into octane layered material and everything seemed to show correctly for a while but after trying to plug in a curvature node into layer 3 things broke yet again and after deleting the rest of the nodes, the view remains broken.
