Multiple shaders and execution sequence...

[drmz0counting]

Hi,

I am learning shader programming and wanted to know if I have more than 1 vertex shaders(say for example shader A and shader B) for an object, then I want know what is the sequence of execution of shaders.

If it is the addshader which controls the sequence, then is it possible to change the sequence in the runtime if required?

thanks in advance.

thanks,
drmz.
