Displacement Problems

Post by iErik » Fri Jul 23, 2010 7:04 am

I am using SkIndigo 2.4.4 with Indigo 2.4.6 and am having problems when trying to use displacement maps. Any time I try to render a material that has a displacement map applied, I have to set the max subdivisions to 4 or less or it will crash. The other problem is that when it does actually render it looks nothing like it is supposed to, having very strange patterns and colors. I included the rendered image of a test scene I set up, along with an image of what it looks like in sketchup and the packed indigo scene. Any suggestions would be appreciated.

Hey Eric,

Indigos subdiv is broken since some time: http://www.indigorenderer.com/forum/vie ... 387#p90387
During the last GPU beta versions it was broken even more, and now also generates artifacts if smoothing isn't used :/

Only way to solve this is atm is to subdiv the mesh in your 3D app...

A small tipp: To avoid the "breaking" of your mesh on the corners, you have to set "normal smoothing" in your 3D app to the max (no idea how this is called in SketchUp).
