Hi everyone,

I am working for a relighting system, the AOVs includes the ST texture
coordinates output from renderman, but how to transform these
coordinates from renderman to opengl ? I think I only need to flip
the t component, just like this
ST in gl = vec2(S in RM , (1 - T in RM) ), but it seems that it's
wrong, but how ?

Thanks very much.
