Hi All again, One more forwarded question. >>>>>>>>>>>>> I had a few questions about vertex shaders, fragment shaders, and textures.
First, if I write my own vertex shader, am I required to also write a fragement shader? If the answer is no, then when I write the vertex shader, what functionality must I include to ensure that all of the information that the vertex shader passes by default is still being properly passed to the fragment shader? For example, do I have to set the varying outputs of the vertex shader since I am changing the vertex shader? With regards to textures, do I have to explicity define each texture that I am using as a uniform and add it to the fragment shader? Or when I add the texture to the stateset, is there a way to access in the fragment shader without using the uniform? Is there a limit to the number of textures that a vertex can have? Thanks for the help. Larry
