Does anyone have experience with successfully exporting transparent materials from Blender 2.8? I’ve read on various forums that this _should_ be possible however, I’ve tried several different material configurations in Eevee and have had no luck yet. Any ideas welcomed. Thank you. ---

Did you change blend mode ? ![image](https://blenderartists.org/uploads/default/original/4X/d/4/f/d4f81da2ce0a7f519a8062db1a21340d348bcab9.jpeg) (edit : and remove show backface also) ---

Thanks Warnotte. That works in Blender however it appears opaque when exported as a .gltf/.glb Have you tried exporting it as a .gltf from Blender? Thanks ---

No i din’t tried. Are you sure, the viewer you use for glb/gltf has the ability to display transparent and so on ? ---

I’ve tested it in [https://gltf-viewer.donmccurdy.com/](https://gltf-viewer.donmccurdy.com/) and [https://sandbox.babylonjs.com/](https://sandbox.babylonjs.com/) both of which support transparency I believe. After some research it seems I need to be working with the alpha channels… ---

You’ll want a Principled BSDF material using an alpha channel and either the “Alpha Blend” or “Alpha Clip” blending mode enabled. That exports correctly for me in a recent Blender 2.8 beta: ![32%20AM](https://blenderartists.org/uploads/default/original/4X/7/6/1/761e2183f29a37aaf9abd3ddd890ee62cb5b0103.png) glTF currently supports a subset of the Principled BSDF values: - Base Color - Metallic (`B` channel) - Roughness (`G` channel) - Normal - Tangent - Blend Mode (Opaque, Alpha Blend, Alpha Clip) Documentation in progress: [https://developer.blender.org/D4082](https://developer.blender.org/D4082) ---

Hi Don, Thank you for your reply. Could you please send a screenshot of the node graph you’re using? I’m not having much luck. ---

Only the Principled BSDF node is needed, but you’ll also want to set _Alpha Blend_ mode in the material settings sidebar, per screenshot above. ![37%20PM](https://blenderartists.org/uploads/default/original/4X/6/d/f/6df97918031988375120c37d3c578e2a4e534f0f.png) The opacity shown in the Blender viewport seems to be independent of the alpha value, but the alpha value will be exported correctly. ~~I’m not sure if that’s a bug in the 2.8 beta or something else.~~ Per [https://developer.blender.org/T52189](https://developer.blender.org/T52189), this is a current limitation in Blender. ---

I’ve used just the Principled BSDF and Material Output nodes and can’t understand why this won’t work. The transparency appears in _Additive_ Blend Mode but not in _Blend_ or _Clip_. I’ve attached the .blend file. [transparency-test.blend](https://blenderartists.org/uploads/default/original/4X/9/4/5/94590408aea461b212610b8770f9284fce85f934.blend) (698.1 KB) ---

Hm, the model you attached does not show transparency in the Blender viewport, but when I export (from a recent 2.8 beta) it does look correct: ![36%20AM](https://blenderartists.org/uploads/default/original/4X/7/b/2/7b2a753c0ffae1e25f630405c989fa297d138106.jpeg) ---

In that case I’m thinking it has to be that my export settings are incorrect or my version of Blender is causing the issue. I’m on version 2.80 2018-11-30. I’ve tried various export settings for both .gltf and .glb. I’ve attached the latest unsuccessful attempts. Ideally I’d like to export as .glb. ![export-1](https://blenderartists.org/uploads/default/original/4X/d/c/e/dceac4d84fe3c485ecf1db5e3bbca11325e0377c.jpeg) ![export2](https://blenderartists.org/uploads/default/original/4X/0/e/4/0e42ed813774910b84edea34e992461c9657c934.jpeg) ---

Oh, yes the latest Blender 2.8 beta has a lot of updates since November — I’d suggest trying to reinstall it. In particular I think this issue was fixed in December: [https://github.com/KhronosGroup/glTF-Blender-IO/issues/105](https://github.com/KhronosGroup/glTF-Blender-IO/issues/105). ---

Success! That was indeed the issue. As soon as I used a later version of Blender 2.8 it worked. Thank you ---

I’m still experiencing this issue. I have used current stable 2.83 and also 2.90 alpha to export gltf and glb… I’ve tried all the suggested material setups but I still can’t seem to achieve any transparency. I’m using this site to preview my models before uploading to an AR test site: [https://gltf-viewer.donmccurdy.com/](https://gltf-viewer.donmccurdy.com/) Any ideas what I might be doing wrong? ---

You’ll likely need to share more details to get help — can you share a `.blend` file, ideally, or perhaps a screenshot of the material configuration? What is the blend mode set to? ---

I am experiencing issues with transparency like this as well. I had been seeing neat transparency in Blender 2.81 but then it was opaque in GLTF viewer. When I updated to 2.83, I got transparency in the GLTF viewer but it wasn’t the same. In GLTF viewer from 2.83 ![image](https://blenderartists.org/uploads/default/original/4X/d/b/8/db8d9d8ade23a426a5499b1a304db441bfa01848.jpeg) ---

When I connected both the color and the alpha from my image texture it seemed to work. Not quite sure why…but Hooray! ![image](https://blenderartists.org/uploads/default/original/4X/4/0/4/404d5345976d6cf7a002188b25d7cb03d35383e1.jpeg) [Next page](https://blenderartists.org/t/blender-2-8-transparent-gltf-glb/1141699.md?page=2)
