I need to know how I could flip and environment map around through hlsl or asm without messing with the environment map at all.
What I mean by this is I want the surface to reflect what is under it or over it(if i am looking through the bottom) ect...
Kind of like a glass shader...
I've looked through other peoples refraction/glassy shaders(that DO use cubemaps. not R2T) ect... and can't figure out how to do this in my shader.

Don't flip the cubemap, reflect/refract the light vector.

Thanks Alexander Esslinger.
I almost figured it out on my own.
This is the fix:

OUT.eyeVector = worldPos - ViewIT[3];

... seems to be sideways now.

hlsl or asm?

I tried to write it into the masked environment mapping ffp of Steempipe, and got one error message after another.
