Perhaps I am missing something very simple, but searching the forum and checking the redbook has not solved it.

2 gridshapes are directionally lit by gl.sketch. one object is in front of the other. one should appear eclipsed by the other, but they are both lit the same. i thought this could be dependent on the drawing order of the objects in the gl.sketch command list; however, it seems not to matter where in the command list they are placed. i tried gldisable depth_test, no luck...blendmodes, no luck.

below is my gl.sketch command list. a patch can be provided, but it is perhaps easier to add a second gridshape to the advanced lighting patch included with jitter's release.

i am sure the answer is simple. thanks for the attention,

ryan
