ok, thats what I thought, so its not only an issue with sampler2DRect.
Thanks for clarifying.

well, as soon as you try to use gl_MultiTexCoord1, it does not work anymore. I think using gl_MultiTexCoord0 sometimes works, even with images of different sizes, but for example the lumaglyph does not work without gl_MultiTexCoord1. I don't know how the information can be passed from gemstate. marius.

if that is the issue, then it should (?) work for sampler2D and texture2D, but I thought we had tested that the other night at the Patching Circle and found it to not work?
ill write a simple shader shortly using square textures as inputs
and we can test the theory out.On Nov 6, 2007, at 9:13 PM, marius schebella wrote:
yes, I was referring to cyrille's mail http://lists.puredata.info/pipermail/pd-list/2007-07/052026.html but that is already included in the current version. also, this mail seems to be related to the problem http://lists.puredata.info/pipermail/gem-dev/2007-08/002873.html marius.

Hi.
I was working a bit with Marius on porting the shaders, and would
love to figure out the issues with multitexturing with GLSL programs.
If a developer (chris?) would be kind enough to point me in the right direction...Marius mentioned an email a while ago pointing out a typo in a
GEM c file. Reports indicated that fixing this typo resolved
multitexturing issues. Marius checked the latest GEM builds included with Extended (0.4.xxx), which do include the fix for the typo (i rather than 1), however neither of us seem to be making any leeway wrt
multitexturing.Id love any pointers.
Thanks,

hey, I was working on shaders recently and put some stuff online http://www.parasitaere-kapazitaeten.net/Pd/4shaders shader #3 is the most advanced, uses a normal map texture. but I am still running into problems when using multiple
shaders. the problem (again) is, that gl_MultiTexCoords1 does not get the
correct values passed from GEM. so the 4th shader should use two images of different sizes, but
I only got it working very rudimentary. If anyone can help me with
this, it would solve a very big problem! (chris?) Thanks to vade so far for his support! marius.
