[GEM-dev] glsl and texture

[cyrille henry]

hello,
it's working!

moreover, i'm happy to see you're felling well.

it was a pix_image / pix_texture position problem.

i think i'll have some examples to share in a few day...

just a question : is it possible to use 2 textures?
(using 2 pix_image / pix_texture in the same gemchain?)

thanks a lot

Cyrille
