Re: [CsMain] Reflectivity of a surface

It was mentioned that the engine uses the diffuse texture to modulate light
and give the impression of more or less light being reflected by a surface.

Can't Mohit's tool do the same? In other words, it could read the texture
and use it as the answer to his question of what percentage of photons are
reflected from a surface.
