Model Support

File types

  • glTF (v2.0 or later)
  • OBJ
  • glb

Model Weight

Many things affect model performance, including differences in hardware, model settings, etc. In general, we recommended maximum polygon count for models is 400k assuming you have one material on your mesh. Additional materials will significantly reduce performance and may need to be offset with a lower poly count.

Model Settings

model settings gltf

Material Types

  • Metallic allows you to add a metallic reflective sheen on the object
  • Specular allows you to modify the smoothness of the object
  • Vertex Lit is useful if your model unexpectedly has no color with the other two material types. This setting will color based on vertex colors

Material Settings

Allows you to adjust the appearance of the model's material after selecting a Material Type.

Animation Controls

Note: These settings only appear if your model is a glTF and has animations.

  • Play is a toggle that plays and pauses the animation
  • Animation Speed changes how fast the animation plays

OBJ Texture Settings

Note: These settings only appear if your model is an .obj file. If you don't have an .mtl file or the textures don't load correctly, these options can help by allowing you to load in new textures.

  • Load Albedo Texture allows you to set a base color map for your model
  • Load Specular Map sets the specular channel
  • Load Emission Map sets the emission texture
  • Load Bump Map sets the bump or normal map

Lighting Settings


Lighting Settings adjust the overall visual presentation of your scene.


  • Use Backdrop toggles whether or not to show a backdrop
  • Backdrop Distance moves the backdrop, where "0" sets it equal to your current focal point and "1" sets it all the way to the back.

Light Position

Changes the direction of the Directional Light

Light Intensity

Changes the levels of various light properties in the scene

Quality Settings

If your computer cannot meet the demands of your 3D model, quality settings will help mitigate some of the render latency.


Quilt Render Quality

Sets the quality of the 3D rendering in the Looking Glass. This is the single greatest determinant of both the visual quality and the frame-rate of the scene.

3D Cursor Precision

The lower this value, the less accurate your 3D cursor will be in following the depth and the normal vector of the model. Lowering this accuracy will slightly help with performance.

Model Loading Timeout

This timeout is the length (in seconds) the app will wait before cancelling a model import. You may need to increase this value for complex models on lower-end computers.

All of the settings under the "Quality Settings" tab will be stored by the app and set to your preferences each time you open it up, so if the first time you run the app your frame-rate is too low and you need to drop the quality settings, you won't run into this issue the next time you open the Model Importer.
