Many factors affect model performance, including differences in hardware, model settings, etc. In general, assuming you have one material on your mesh, the recommended maximum polygon count for models is 400k. Additional materials will significantly reduce performance and may need to be offset with a lower poly count.
Metallic and Specular are two common variations of PBR shaders. Both give a representation of the material of the surface.
Metallic Shader is specifiically for metal and exposes two properties:
- Metallic - Adjusts how metallic (and therefore reflective) the material is
- Roughness - Adjusts how rough or smooth the material is
Specular Shader is for non-metalllic materials and exposes one property:
- Glossiness - Adjusts the glossiness of the object, changing how it is affected by lighting
Vertex Color Shader is useful if the model unexpectedly has no color with the other two material types. If it uses this shader, it means the model itself has some color data stored for each vertex. If the model should have color but is white after loading it into the 3D Model Importer, try using the Vertex Color shader.
Increases or decreases the level of complexity of the mesh on the 3D model. This may take time to process.
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 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.
- Horizontal Angle changes the direction of the Directional Light horizontally
- Vertical Angle changes the direction of the Directional Light vertically
- Directional Intensity changes the intensity of the directional light in the scene
- Ambient Intensity changes the intensity of the ambient lighting in the scene
- DoF Intensity changes the intensity of the depth of field focus blur in the scene
- AO Intensity changes the intensity of the ambient occlusion in the scene
- Bloom Intensity changes the intensity of bloom in the scene
The bottom buttons "Save Settings", "Reload Settings", and "Set to Default" allow the user to adjust the model's object and lighting settings as well as its framing in the Looking Glass and save these settings.
Save Settings - Save the current settings on the 3D Model
Reload Settings - Reload previously saved settings on the 3D Model
Set to Default - Return 3D model settings to 3D Model Importer's default settings on load
If your computer cannot meet the demands of your 3D model, quality settings will help mitigate some of the render latency.
Quilt Resolution 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.
Optimizes the model's performance to the user's preference. No optimization can lead to slower rendering. The recommended way to improve performance. This method will create some artifacts but can greatly improve rendering speed.
Turn on or off the post-processing effects that are set in object settings. Turning off post-processing effects will allow object to render faster.
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 3D Model Importer.
Various types of 3D modeling software have various levels of support for the accepted file formats (.obj, .glTF, .glb).
|Sketchfab||Model Repository||.glTF download available for all downloadable models|
|TurboSquid||Model Repository||Search can be filtered to show models that support obj files|
|Poly||Model Repository||Search must be filtered to only show "Blocks models" that are "Remixable"|
|Blender||3D Modelling||Native .obj support|
|Maya||3D Modelling||.obj support via Plugin|
|Cinema 4D||3D Modelling||Native .obj support|
|Paint 3D||3D Modelling (Native to Windows)||Native .obj support|
|Everything else||N/A||First check to see if it natively exports an accepted format. If not, this list of glTF converters and exporters may be helpful. Of all the tools listed, we've found success using Sketchfab's conversion tools.|
