So the problem may be that gl4es doesn't support the necessary gl extensions :-/

ptitSeb commented 3 years ago

gl4es doesn't work with the "OpenGL 2.0" driver of ioq3 IIRC. For the gl driver to GL 1.0 and it should work. (it use old GL ARB shader, that needs some debugging)

Moldytzu commented 3 years ago

I will try that!

Thanks you for creating this great library for single board computers! It works.
