- Final file format - .GLB (with Embedded textures).
- Model size:
- The final file size should be less than 40MB.
- The optimal size is 15MB
- Polygons count.
- Very important for app performance.
- Optimal - 100k, Maximum - any, but better less than 500k.
- The app can work even with more than 1M polygons but could cause poor performance on some devices.
- For best performance better to keep all textures in size of 1024x1024 px.
**2k textures are ok but don’t use bigger than that. Keep them in the “Power of 2” (512x512, 1024x1024 and so on).
