SphereMask and Absolute World Position in Mobile Devices ( AR )

Development Rendering
1

I’m trying to use a sphere mask on a material, to mask off some parts of it on Android and iOS devices for an AR Project. I provide a Material Parameter Collection to the material which i edit in a blueprint, to set the origin of the masked material.
Everything seems to be working correctly on the Editor and the Mobile Preview mode (ES 3) on the Editor.
But the material is not working on both iOS and Android Builds. Any idea what i may be doing wrong ?
The material type is Masked

This is what my Masked Material looks like:

Hi 3piczzor, did you find a solution since?
It seems the “Absolute World Position” node not working on some mobile devices ("Absolute World Position" not working in Mobile - Rendering - Unreal Engine Forums). Did you find a way to bypass this problem?
