3D Model Optimizations
- The model should be scaled to real life sizes and the origin point should be at the center of the model before exporting.
- For the model to be efficient, the poly count should be kept as low as possible. All the textures exported should go through a compression pass using online compressor tinypng.com or similar.
- Lower the size of the model, the better would be the loading speed.
- Ensure the number of vertices/triangles/polygons is as low as possible.
- Ensure textures are compressed
- Bake the textures into the model. Keep textures less than 4k resolution.
Element | Recommended Max Triangles Count | Recommended Max File Size |
|---|---|---|
3D Models - Cumulative | 50K | 50MB |
Colliders - Cumulative | 5K | 5MB |
The above recommendation is for the whole scene. This is, less than 50k triangles, 50MB file size in total for a scene (i.e. the sum of all triangles/file sizes for all 3D Models in a scene).
This is workflow we recommend. https://sketchfab.com/blogs/community/sketchfab-archvis-workflow-based-on-vray-baked-textures/
- Decide to combine all objects or do them as individual objects
- Texture your model correctly with properly unwrapped UVs - no overlaps
- Setup good lighting and test it in quick render modes
- Bake and export textures
