Multiply Emissive by diffuse option

Sketchfab can ALMOST support prebaked global illumination for static lighting.
In theory multiplying a baked rawGI pass (from vray for example) in the emission material slot (which supports multiple uvs for a lightmap) with the diffuse texture/colour slot should allow us to have static baked lighting in our PBR scenes.

Example tests below show what I mean.
