Rect Mask not working on Mobile Build but in Unity Editor

[Luan12134]

Good Evening,
I am having a bug where the particles are showing on mobile but they are not masked.

On Editor it is working perfect, but building the project for iOS does not work as it should.

On iOS Build, it seems that the Particles attach to the object are ignoring the Rect 2D Mask Property, whereas on the Editor everything is working fine.

Do you have an idea?

I am using UI/Additive and I am using AssetBundles to download the prefabs from a server.

Thank you for your reporting!

1. If the prefab is built-in instead of in an AssetBundle, does UIParticle function correctly?
2. Do objects other than UIParticle ignore RectMask2D?
3. If using Mask instead of RectMask2D, does it function correctly?

Could you provide information on these questions?
