Hi, Corona Light is basically illumination. So it will work provided that the rendered material is Corona Light mtl, or Corona mtl with self illumination.
More elements are planned. Would be great if you could make a list of elements which you would find useful.
I second that! It will be amazing if we could extract only the lighting.
As of now, when you render the CoronaDiffuse you get the texture with it, so you can’t composite only the light with another diffuse texture in Unity, for instance.
