I'm trying to export a ring that has some transparent parts, but when i open the file that i exported, my transmission map is not there anymore, so the ruby becomes opaque. (No matter the format .fbx , .gltf ...)

You plugged your Transmission map into Alpha input.
Alpha input considers white color as opaque.

  • Thats's the problem, it's not me that plugged it, but it is automatic when i export it, that's what i don't understand. Why every map is supported excepted the transmission map ? – Peach_is_Tasty Nov 07 '20 at 10:25
  • Hey :). Exporting materials is tricky, and often not fully supported. Even the newest gITF doesn't support everything. Related answer: No materials on .fbx import – jachym michal Nov 07 '20 at 10:32
  • I already read this that's why i tried to bake maps, and use .GLTF but it solves nothing. There surely should be a solution, how is there so many glass objects on CGtrader made with blender ? – Peach_is_Tasty Nov 07 '20 at 10:43

    Exporting transmission textures to glTF is supported by recent versions of Blender (see https://github.com/KhronosGroup/glTF-Blender-IO/pull/1094), but note that it's a newer feature in glTF and not all viewers support it yet. A good glTF viewer to test such files is https://sandbox.babylonjs.com/. – Don McCurdy Jun 29 '21 at 17:42
