OpenGL clipping planes (within jit.gl.sketch) don't seem to be working on max 5 for me (on Dell Laptop, windows XP). This simple patch that uses them works fine on max 4.6, then the same patch doesn't clip on max 5. Have any of the command/parameter names changed? Patch as text is pasted below, but it is just feeding a "glclipplane 0 1. 1. 1. 0." to a jit.gl.sketch (which has received "glenable clip_plane0").
Any ideas greatly appreciated!
