Allow Base Color and Alpha Map textures to be combined on export

See original GitHub issue

Currently, it appears that alpha transparency in textures can only be used effectively when it’s included in the Base Color texture.

It would be amazing if the exporter was capable of combining the Base Color texture with an Alpha Map/Mask on export, possibly via Add Shader or Mix Shader + Transparent BSDF (or whichever makes the most sense).

Example:

This would greatly benefit project workflows where separate Alpha Maps/Masks are used.

Thanks for the consideration and all the great work.

@donmccurdy It appears I may have been wrong about improvements in regard to Principled BSDF shader’s Alpha preview in Blender viewport, unless there has been a recent regression. I was using the Background shader, which previews as expected, but still not the case for Principled BSDF. Sorry for the confusion.

Might be good to have the importer use the new alpha input on Principled BSDF, but, that has to wait for 2.79 support to go away. It’s 2020 now so it’s just whoever has time to make it happen, I think.

In the meantime I think we can consider this issue resolved.
