Scene load faulty on iPhone iOS 15

Hi there,

I have an issue with both of these scenes. When I load either of them, the loading icon plays but then immediately goes back to the play button without loading correctly.

It’s happening on iPhone XS, running iOS 15.

A phone restart solves the problem but it bugs out again soon after.

All help is greatly appreciated
Thanks

It seems that the issue is caused by scene memory requirements exceeding the memory available on mobile devices. In particular, the scene has 7 lightmaps - could you check if setting Max lightmaps to 3 and re-baking the scene solves the issue without sacrificing the quality significantly?

ahh this makes sense, I have been setting it to max, and in most scenes it only uses 2 or 3 anyway.

Hi @wojtek, I have the same problem. I can’t open the work in iOS. How can I solve this? https://rgg.shapespark.com/secolo30/

This scene has 40M triangles and 8 lightmaps. I am afraid it’s way too much for mobile devices to handle the scene. You’d need to optimize the geometry, ideally to 3-4M triangles and reduce the lightmap count to 2-3 to ensure that the scene works well on an average mobile device.
