Hi, Is it possible to add attributes other than the predefined ones to a VArray passed through the vertex shader, and have the vertex_shader interpolate them?
So far, if I want to pass some arbitrary info onto the fragment_shader, I've just been forcing it into any of the predefined slots (PW, PL, N...) that I don't need in the fragment shader. But I was wondering if it's possible to add new attributes. I notice AttribContext has a "copy_to_channels" method that sounds like I could use for this, but I'm not sure how to go about creating a new AttribContext, and filling it with my data. In any case, would that be the best approach to append arbitrary data to a Varray? Can anyone share any pointers/examples/help? Many thanks, Ivan
