General performance recommendations

Be careful, standalone VR is very sensitive to the number of objects, sub-objects, and matrices - this can greatly affect performance.

Recommend 200-300 objects/materials per scene (Draw calls) for Quest 2. Note that ShapesXR interfaces, avatars and other elements can take 50-100 draw calls.

If it is possible to merge individual geometries into one model and merge textures, this will help you save performance in your scenes.

To improve the performance of your VR space with imported models, we recommend optimizing your models.

If your model has multiple textures and materials, we recommend combining the textures and materials into one texture and one material.

This helps solve many potential issues. Models with fewer materials work better in mobile graphics.

It is critical to make one texture and material for OBJ format. But for glTF or GLB formats, we also recommend minimizing the number of materials and textures.
