I'm using blender 3.1.2, and I'm looking to export a model which is using a variety of typical texture maps. This all works fine on its own, exporting flawlessly into a .glb through Blender.
The issue arises when I try to use an alpha map, in this case made through Blender's Texture Paint tools, but the issue occurs even with a loaded alpha map. The transparency is perfect, but the value drops significantly inside the exported .glb file.
I just want to reiterate that the texture works as expected in a gltf while in isolation from the alpha map, and even with the alpha map present it appears as expected inside of Blender itself. The problem seems to be somewhere in exporting to the gltf format.
I've fiddled with it, but to no avail. If someone knows what's up, I could certainly use the help!
