#Actuallpcstr

I was thinking about the feasibility of using a flexible anisotropic specular as the primary BRDF in a deferred shading setup. You'd obviously have to store two roughness parameters in the gbuffer instead of one. My question is, wouldn't you also have to store the tangent and bitangent vectors, since those are needed by the BRDF? That would require a lot of space in the gbuffer.  wacko.png
