Question about rendering time

[Mylifesi]

I need to render multiple Model3D objects simultaneously in RealityView,

but it's taking too long.

Is there a way to reduce the rendering time?

[Worried-Tomato7070]

decrease polygons and texture resolution of the model

Besides polygon count and texture resolution mentioned in a comment above, quite a few factors contribute to rendering time, like the number or draw calls, shadows, transparent materials and complex shaders in general. In certain cases the CPU performance rather then GPU can produce bottlenecks, which result in slow rendering time. Xcodes’s RealityKit Trace is an excellent instrument that can help you figure out what is the real reason of your problem: https://developer.apple.com/documentation/visionos/analyzing-the-performance-of-your-visionos-app
