How i can achieve the same cubemap reflection effect of this FixedFunction code
Code:

---

 
    TexCoordIndex[1] = CameraSpaceReflectionVector;
    TextureTransformFlags[1] = Count3;
    TextureTransform[1]=<matMtl>; 
 

---

where matMtl is a modified matViewInv to calculate reflections in assembly??
I tried to simply paste this code before or after the shaders but it didn't work...
