Displacement on custom meshes - problems
Posted: Wed Jul 19, 2017 8:42 pm
Hey Guys,
I encountered an unexpected problem. I was going to texture a custom mesh with a displacement map. I thought it would be as simple as creating the mat and throw it on the object. But: Octane either crashes or is showing nothing. The map works perfectly fine on parametric and converted objects. See the attached screenshot below. Cube works fine, the splitted piece of my geometry shows nothing, as well a created mesh with the polypen. What am I missing?
Assigning the material to a selection of the main object and switching to another projection mode beside UVW does work but is slow as hell.
Here you can see the crashlog when switching to cubic projection on the splitted part.
In short: how can i apply a displacement material to the curvy mesh?
