- Final file format - .GLB (with Embedded textures).
- Model size:
- The final file size should be less than 30MB.
- The optimal size is 15MB
- Polygons count.
- Very important for app performance.
- Optimal - 35k, Maximum - 100k.
- 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 power of 2.
