Materials and Textures



  • James

    Hi @samplia,

    I'm afraid there has been no progress on supporting animated textures in the "regular" viewer, it can only be done with the Viewer API:

    For what it's worth, Twinmotion and Sketchfab are both part of Epic Games, and we are working on tighter integrations between the various tools (especially Quixel and Twinmotion). So, maybe we'll be able to handle such materials at some point.

    Hey again @James,

    I see here

    that: UV transforms can be imported and exported via glTF

    But with the  when we Publish to Sketchfab the textures are not uploaded (understandable you only post the glTF) with the glTF file but also the material is not correct.

    When it finished uploading I saw in the 3Dsettings that the Emission was ON ( my materials had only a basecolor texture, normal map texture and some tiling/scale variable to check the UV Transforms, I am using HDRP/Lit materials.) and after I uploaded the textures and assigned them properly the  UV transforms was the default ones.

    So is it that the glTF the api is sending has no material info or is it a compatibility issue with HDRP?

    If the textures was in the zip the the api is posting would the textures be assigned properly with UV transforms ?

    Overall, you think I have better compatibility with glTF over obj + mtl ?

    (exporting models + materials + textures from unity, uploading to Sketchfab )

    If you have any documentation about the format of a glTF file or anything that can help me I would appreciate it.

    Thank you for your time.
