I use Blender 2.82, and I use the principled B.S.D.F. How do I export a 3D object with transparent textures? Like glass and stuff. Making the obj, fbx, and files like that. The rest of it works fine, like the lights, the height, normal map, textures, etc.

I look in the 3D viewer, there's no transparent textures.

Use gltf/glb exporter to export with transparency .

The opacity alpha has to be in color image. (Check the documentation for correct export settings and node setup)

gltf format supports :

  • Color + alpha
  • Metallic + Roughness + AO
  • Normal Map

all other maps will be ignored
