Proposal: Support `Alpha` settings in material even when image texture's file format is PNG

Received. That UI did not even exist at the time when this part was written. Think that so other people's exports are not broken, the only time it would be consulted would be to override existing logic when 'None'.

The line 135 reference is when the exporter was required to bake do to a material which will not export. This UI will not exist for this temporary texture. That is controlled by the exporter's Mesh custom properties.

The image texture node is currently read in this file . It is currently assigning alpha without using the field. Change needs to be there.

Will need to check how that interacts with Texture.py, but not for a while.

Post import, if you got the material in question, you could override with code (based on the type texture) for now:

material.(emissiveTexture | albedoTexture).hasAlpha = false;
