I used 2 clipping planes and they work well. The object has been clipped by these two clipping planes, no error occurs. But when I want to change clip status of the device by using the method ::SetClipStatus, it has no effect no matter how I combine the D3DCS_* bits, I created the device by using D3DREATE_SOFTWARE_VERTEXPROCESSING flag. And I have checked the device caps, MaxUserClipPlanes = 6; [Edited by - Luffy on November 13, 2004 3:30:24 AM]
