So I'm working on my motorcycle exercise submission for Jonathan's texturing course and I've applied a mud texture to some of the painted surfaces. It looks ok with a just a bump but I want to use a displacement on the mud too. I figured I could use the same color ramp that masks where the mud is placed as a factor for the displacement but I'm not getting the result I want. Either it shows nothing or displaces the whole bike like a balloon. I know it's not easy to give advice without seeing the nodes but if anyone has a suggestion, or even an example of a node setup I could see, I'd appreciate it.
Do you mean something like this? (I know it doesn't look like mud):
Not sure why it doesn't work in your case...seeing your Node Tree would indeed be really helpful
Oh wait, are you using the original motorcycle as it is....that has not enough geometry for a nice displacement! You'll just have to be happy with Bump or Normal Map.
Yes and yes. Thank you for that example as that is the exact effect I was attempting to produce. Your node tree looks like what I have and I’m using the original bike UVs. Wouldn’t adding a subsurface modifier add the geometry I need?
A Subsurf wouldn't create regular topology. My Cube actually looked like this in Edit Mode with an additional Adaptive Subdivision on top:
Hmm. I might need to settle for a bump after all, which would be ok. Not ready to give up yet, though.
