3D Models importing tips

Known issue:
Models with multiple materials and submeshes have a buggy geometry.
Solution:
You should split the model by materials (submesh) and upload the model in separate parts.
Uploading an OBJ file with textures:
For textures to be included with models, it’s important to upload your OBJ file along with the MTL (file with a description of material settings and links to textures) and all of the associated images in one upload. To avoid problems with importing textures, before exporting a 3D model from your 3D editor, make sure that the used textures are in the same folder where you export the model. This should automatically create an MTL file with the correct texture description.
After that, it is worth checking the results before uploading. If you see issues with your import inside ShapesXR, recheck the results and try uploading again.
Check your MTL file before uploading:
If you upload an OBJ file with textures, you should check your MTL file: Open your MTL file using the Notepad app.
The line that starts with “map_Kd” should contain only the name of the texture and not the path. If it has a path, remove it and save your MTL file before uploading.
If your model has multiple materials and textures, check each map_Kd line in your MTL file.
A simpler and more flexible alternative to importing OBJ files is to use the glTF and GLB formats. The format is actively supported on the Web. For example, you can download any downloadable model from SketchFab in this format.
Allows you to import more complex models with many materials and textures, without the complexity of importing OBJs.
Upload your glTF files as ZIP files
We do not support skinned meshes, light sources, 3D cameras, or animation for glTF/ GLB.
Apply materials to textures of models:
You can also assign a material to model textures. If your model has textures with transparency, apply any material with 0.98 Alpha (or less if needed) to your model.
You can apply Unlit material with white color to get a bright texture image, that will not be affected by space lighting.
To improve the performance of your VR space with imported models, we recommend optimizing your models.
If your model has multiple textures and materials, we recommend combining the textures and materials into one texture and one material.
This helps solve many potential issues. Models with fewer materials work better in mobile graphics.
It is critical to make one texture and material for OBJ format. But for glTF or GLB formats, we also recommend minimizing the number of materials and textures.
