Material not double sided when exported in GLB format

Unity Asset Transformer

Hi,

When I try to export a 3D model with Pixyz Studio in GLB format with a PBR material, this material looks like a little bit transparent on the 3D model even the PBR material doesn’t use transparency layer. Same problem on Windows viewer and Babylon Sandbox viewer

Below a picture where we see this problem

Any idea how to correct this problem ?

Thanks for your help.

Hello @OneDesign !
Can you please provide a .pxz scene and the .glb file generated by Pixyz Studio?
If you can’t do it here, please use this form to create a Support ticket.

It could be the way the your material is in Babylon Viewer in the Transparency mode.

Does the model look correct when you import it back in Pixyz Studio?

Thank you!

Thanks for your reply.
When I modify by Alpha Test it’s works corrrectly.
Do you know how to export with Pixyz Studio to show correctly by default in Babylon ?

The first GLB works correctly when he is imported back in Pixyz Studio

Hello @OneDesign

This cannot be done on Pixyz side.

Acutally, to avoid such issues, here is the best practice the Khronos Group (glTF format developers) gives regarding transparent geometries (see here): the opaque and transparent components need to be on separate meshes and have a separate material

Also, here is some documentation from Khronos Group about Alpha coverge with glTF.

Hope this helps!
