[substance designer] How can I apply dirt to a complicated shape using the nodes?
Hello. I have been using SD for a long time so this isnt a begineer question, for this example I've used a blender square to explain my question. If you look at the image you will see what Im looking for, ideally a node, which will apply dirt, lower to the ground= more dirt, higher from the ground=less dirt. I assume some… -

No problem, let me know how it goes. When you used the Dirt node did you have "Use Tri Planar" set to True? -

Here are some things I've just tried. none of them quite hit the mark, but Im using that top to bottom node. with triplanular for seamlessness. -

If you feed the position and world space normal maps into rgb split nodes you can extract masks for whichever direction you want and then muck around with them -

thanks i will look into that later this week. -

The red channel is X, green Y and blue Z In the position maps they'll be simple gradients, the wsn map is what direction each pixel is facing in. You can work out what they do by simply viewing each channel separately on your model. -

i sort of understand, but if you have a link to explain it a bit it would help a lot!
