Hi All,

I am playing RenderMonkey to create a caustics effect by morphing
DiscoLighing sample. I have created something as expected and now I want to
port this vertex and fragment shader to OSG. At that point RenderMonkey can
automaticaly calculate Binormal and Tangent value and passes them vertex
shader in

attribute vec3 rm_Tangent;
attribute vec3 rm_Binormal;

What can I do to pass this value to vertex shader on OSG?

Best Regards.
