that would be the first time.

reducing it from 40 to 5 did not help

thanks cyrille for having a look.


i just tried the same on a different machine:
OS X 10.6.8 with a NVIDIA GeForce GTX 285
print gives me:

[glsl_geometry]: glsl_geometry Hardware Info
[glsl_geometry]: ===========================
[glsl_geometry]: MAX_GEOMETRY_UNIFORM_COMPONENTS_EXT: 2048
[glsl_geometry]: MAX_VARYING_FLOATS: 60

[glsl_geometry]: MAX_TEXTURE_IMAGE_UNITS: 16
[glsl_geometry]: MAX_TEXTURE_COORDS: 8
[glsl_geometry]: compiled last shader to ID: 3

but running the shader only gives me maaany of those:

GL:Invalid operation
