Hi, I've been working through the Jitter tutorials and got to Tutorial 33 (PolyColorBlend), and several parts of it don't work properly with GL3 (working when I reload with GL2).

The bits that don't work are the cull_face and possibly the blend_mode too. I think it's because in GL3 the cull_face either doesn't work with wireframe mode, or needs something else changed to get this to work the way the tutorial describes it.

Any thoughts on this?

Hi Sebastian, unfortunately no solution here, just to say I experience the same issue:

With @cull_face (jit.gl.gridshape) under GL3 I see no difference between frontface and backface although trying to render them differently in @poly_mode.

Is there any workaround for this?

cull_face now seems to offer a fourth value "3: 2Pass" which I couldn't find in the reference so far.

It only mentions 
0: Off, 1: Back, 2: Front

thanks for the report. This may be a simple issue in our drawing logic, or it may be something more fundamental in the driver that will require modifications to our shader generator.

in either case it is now on our radar and we will investigate.
