First of all, I appriciate the new custom asset library a LOT! I've been using Pieter 's custom asset creator to this point, and am now looking into moving the library to the official asset library.
We do our 3D assets with Blender. Importing to GLTF has had it's issues; sometimes, duplicated or mirrored parts of the models show as pitch black. Sometimes it's pretty random and tricky how we fix these problems. Mirroring the object in Revit flips the blacks to normal textures and vice versa. It has something to do with the 3D geometry, but we're not very long term Blender modelers, so we don't know what causes this.
Now it seems that the official custom asset library simply says "nope" when trying to upload any of these models that has geometry issue like this. "An error occurred while trying to import the model file. Error message: Unable to convert source file."
What gives, what are we doing wrong?
I attach the GLTF, OBJ and FBX export file from Blender to this post aswell as the original Blender- file.
I appreciate any help a lot!
