Hi Steven, I've tried assigning the attached texture (without running the callback) to a quad in the scene and it is still blank. If your RTT texture is black without any post processing, so maybe you forgot to add any scene below your RTT camera in the scene graph? For example your

I believe you can use a uniform array of samplers. This means the number of texture can be arbitrary and therefore you don't need to recompile your shader based on number of textures. Paul Martz Skew Matrix Software LLC http://www.skew-matrix.com +1 303 859 9466 Johannes Schth wrote:

Hi all -- I've finally had a chance to review the ShaderGen code. If I understand correctly, this was added as a step towards eventual support for OpenGL 3. However, I'm surprised by the OpenGL 2 / GLSL 1.20 nature of the shader code, specifically the extensive dependency on built-in uniforms
