Is 'spawn decal attached' not supported for AR (iOS)?

It works right on the computer, but when I deploy the AR project to the iPhone, the decal is successfully spawned but doesn’t show. I wonder if this function is not supported on iOS.

Thanks!

Correct. Decals don’t work on mobile. As a workaround you can draw your decal to a canvas target, and use that canvas target as a texture in the relevant material. Obviously that’s much more limited in some ways than just using a decal, hopefully your use case is simple!

Thank you!
