I'm making a Transparent Glass Cup in Blender 2.8
I'm using the Principled BSDF --> Transmission set to 1, Roughness set to 0
If I'm not mistaken, if I export it to .obj/.fbx file, the glass cup will no longer transparent and I will need a texture for it to make it transparent again.
Is there any way to do this?
What you should export out is a 'Transparency Map'. Otherwise known as Alpha Map as well
Its a black & white map, where black means 0(fully transparent), white means 1 (fully opaque)
After preparing a transparency map, you can connect it to the transparency/alpha slot in any engine, and it would work the same.
