Render Target UI material black on android

I am using a scene capture component which draws scene to a render target and then I’m using that render target to create a UI material to use on my UMG.

This works fine in pc, but in mobile it’s just black.

i tried multiplying material but nothing changed. Is there a fix to this ? or is there any alternate ways for character previewing similiar to this ?

I’m having the same issue. Looks fine on PC, even in Android Preview mode but when I play it on my actual phone it’s just black.
