Hi

Is there any way to have working custom clipping planes on radeons HD in openGL ?

in my GLSL vertex shader I output gl_ClipVertex, in code i set glClipPlanef(GL_CLIP_PLANE0, PlaneEQ), and enable it glEnable(GL_CLIP_PLANE0);

... on nvidia it works fine - I have the left half of my object clipped (just for test)

... on ati no error is returned from gl - but nothing is clipped at all :/

is there any any reason for this ? gDebugger olso tells that all should be just fine :/
