I uploaded a .blend file, but textures don’t show. They are present and viewable in inspector, I can also select each of them, but they are not rendered.
I also tried uploading in FBX format with same result.
Uploading in OBJ format does not preserve the separation of spacecraft from other objects as I need.
I had a look here ( https://help.sketchfab.com/hc/en-us/articles/202600873-Materials-and-Textures ) but it looks the page refers to an older version of interface, I can’t figure out how to import additional textures.
