hey there,
i'm trying to implement a "hard-light" blending mode, as described on
between two textures using a glsl fragment shader. it's compiling,
linking and running fine in ShaderMaker.
when i try to load it with [glsl_fragment] i don't seem to be getting an
ID on the right outlet though. it never changes from [ 0] which i take
to mean "failure in some way".
the same happens, by the way, with the shaders, both vertex and
fragment, that come in example/data.
a print message on glsl_fragment produces:
[glsl_fragment]: ============================
[glsl_fragment]: MAX_FRAGMENT_UNIFORM_COMPONENTS: 2048
[glsl_fragment]: MAX_TEXTURE_COORDS: 8
[glsl_fragment]: MAX_TEXTURE_IMAGE_UNITS: 32
seems to be telling me, glsl support is acknowledged to be there.
i'm running: pd-0.42.5-extended
my gem version is: 0.92.3
on x86_64 ubuntu 10.10
with corporate nvidia driver, version: 260.19.44
any ideas anyone?
and then i have another question:
if i manage to run the shader, how would i throw the two textures to
their respective 2Dsamplers in there?
prefix [pix_dump] output with the samplers name?
thanks+ciao,
ub
