I'm trying to apply a texture to a group texture, but it seems to crash randomly when applying it. It only crashes when we build two separate jit.gl.world to display the texture in one screen and the 3D object in the other... Am I doing something wrong?

my guess is that the crash is related to the separate displays. can you tell me more about your hardware setup? the main question, are the 2 displays connected to outputs on a single GPU or are they two discrete GPUs?

If the latter situation, you won't be able to share GL resources between the 2 contexts. but let me know the situation and i'll try to offer advice.

The patch is running on a MacBook Pro we are not outputting the result for now, just showing two windows, with two different jit.gl.world, with two different contexts, named game1 and zazou. We will capture and send the frames relative to each world via syphon. But for now, when we try to apply a texture in a specified group in a specified context one of the two that we initialized max crashes... So we can only have one context per GPUs ?

no, contexts on the same GPU are unlimited. I'll need some exact steps to reproduce the crash, it's not clear to me from looking at the patch.

- Get the obj into the jit.gl.model zazou

- Make sure it get displayed in the world zazou

- Get the texture into the jit.gl.texture zazou @name noyaux

- Enable the first world game1
- Pick the 3 preset
- Enable the second world zazou
- Get the obj into the jit.gl.model zazou
- Make sure it get displayed in the world zazou
- Get the texture into the jit.gl.texture zazou @name noyaux
- Press texgroup 2 noyaux
- Crash

ok I can reproduce the crash. Interestingly this doesn't crash with 

 engine, so you may want to try that out as a workaround for now. I'm not sure of the cause, but will let you know if I can figure out an alternative approach with
