| Sep 28, 2022 at 17:29 | comment | added | Asura_Sloth | Yes you are right transmissive materials cannot be vsisble through themselves thats the problem I am facing. So the only solution is to use a separate material on it. | |
| Sep 28, 2022 at 12:21 | comment | added | Don McCurdy | By "opaque" in this case I mean the material cannot use alpha blending OR transmission. Transmissive surfaces are not visible through themselves, or through other transmissive surfaces. The entire material would be considered transmissive once the texture is connected to the transmission socket. | |
| Sep 28, 2022 at 4:55 | comment | added | Asura_Sloth | @DonMcCurdy I have assigned the blending mode to Opaque as stated in the blender gltf documentation. Transmission works if I use a value in the Shader. It does not seem to work for me if i use a texture instead. I am basically trying to achieve the red spheres from this Sample model tinyurl.com/4xhkyuht . The various viewers recognizes that I have transmission plugged in but does not display them. I would highly recommend to download my files and have a look at it yourself. Thank you for replying. | |
| Sep 28, 2022 at 2:46 | comment | added | Don McCurdy | To the OP — most realtime viewers today are limited to displaying only opaque materials through a transmissive surface. Surfaces using alpha blending or transmission will appear missing, as you see here when using a single material and a transmission texture. If you find a viewer that supports the "depth peeling" technique, I would expect your original export might work. But this method is currently too expensive/complex for most viewers. | |
| Sep 28, 2022 at 2:42 | comment | added | Don McCurdy | As a contributor to the Blender's glTF addon, I do not think this issue should have been closed as a duplicate of the (much older) thread about limitations of the FBX exporter. Blender largely supports exporting Principled BSDF materials to glTF when inputs are baked to textures, and the question asked here is a reasonable one with a straight-forward answer. | |

Do not confuse this for FBX, its a GLTF issue.
