I'm totally new to the world of GLSL,
and confused...anyway after running the post effects tutorial sample 'colourise',which kinda works I guess?,I get this error msg to the background console (while the program is running)...

Impossable to use texture "framebuffer" for post effect :
all available texture units are used

Can anyone enlighten me please?

This is the colourise tutorial in the post-fx tutorial section on this site.

It means your graphics card has only one texture unit for shaders (i.e. you can only use one image at a time in a post-fx), which really sucks

One other question then,

Is there any point using post effects if I can only utilise one image.
What could I do with one image,anything remotely eye catching???

Almost all post-fx of the Post-Fx sample of the SDK. I think only the "wave" effect uses a second image.
