displacement/height problems

JVoye

Hello all,
I found someone with a similar problem as mine but it did not solve my issue, so I apologize in advance if this has been covered before. I rendered to texture a height map in 3ds max for this ground plane and regardless of how much geometry and/or tessellation I have applied to the mesh I'm still getting some triangle like tearing in between the stones on the side and underneath the ground plane itself. I tried slightly blurring the height map as I thought maybe it had something to do with the sharp transition between tones on the height map itself, no dice though. Can this issue be resolved? Thanks

Try sub-dividing the floor plane before you import it, there is a max to how many times it will sub-divide in TB2.

Also, you could try parallax mapping instead, swap the normal map model to parallax.

Parallax mapping did fix the stretching on the bottom of the plane but produced some interesting artifacts/aliasing in between stones. Same thing is happening in 3DS. Maybe it's the actual height map that's the issue?

Yeah, you might want to blur the displacement map a bit more. Displacement maps with very sharp angles like that are going to give both parallax and displacement mapping trouble.
