*Be sure to check your camera position and annotations after re-upload - we assume a consistent model orientation and scale.
**Material definitions are compared (based on name) before and after re-upload. If the material name is the same, we keep edits that have been made in 3D Settings. Materials are updated per channel, i.e. uploading a new Diffuse color will not change any other settings for that material. We keep old textures if the new upload does not include new versions. We replace textures if the new version has a texture with the same name.
