Z-fighting & the depthtest

17 November 2012 - 11:44 AM

i'm rendering volumetric clouds, which works pretty well. For the next step, i wanted to render some terrain. Previously the depth buffer was disabled, because i sorted all vertices, so there was no need. But for the terrain i need an active depth buffer while rendering the clouds and then i get massive graphic problems. It looks like z-fighting, but i got no idea how to deal with it. Here are some pictures to show my problem.

Enabled depthtest:

Disabled depthtest:

Anybody has an idea?
Another question:
Is it possible to write to the depth buffer without depthtesting?
