Hi, I need to use FX Composer because I have to debug my shader. I was using Ogre and cg (ps_3_0) before. Previously my app saved values to a floating point texture (containing a matrix) which was passed to the cg shader file. Does anyone know if it's even possible to create a matrix in fx composer, and save it to a floating point texture for future lookups? All I see in FX Composer is the ability to create color and depth targets.

I think I can create the texture in photoshop as a 32bit floating point dds texture....hope this is the answer I need!

Edit: Still not sure if this is possible, I guess the issue is how would you populate it in photoshop with values that aren't rgb colours...
