I have some UI with a scroll view set up like this: ▾ Scroll View ▾ Viewport ▾ Content Scrollable UI More Scrollable UI The viewport has a mask component that uses a stencil to mask the scrollable UI. My issue is that the UI being masked has an instance of this stencil automatically applied to it, and it can't be edited. Because of this, My batch is breaking due to 'Different material instance'. It's important for the batches to batch because it's an Android-based game. How do I solve this?
