It is very important to optimize your projects!
Try to keep your project total size (images + models + audio files + video files) under 10Mb, or even 5Mb.

On your 3D models, do not use oversized textures, and delete all faces that are hidden.

Short loading times and a smooth framerate always make an experience more pleasant for the end user…

Loading time estimation

Above the 3D composition view, you can see an estimation of the time required to load your project, considering the mobile network speed.

How to optimize web AR loading times

Use as less assets as possible, import them once in the assets library and add them multiple times on the composition.
Don't import oversized images.
