I’ve been trying to get basic UI masking working with a viewport->content->content entities heirarchy, but for the life of me I can’t seem to get it to work in play mode. I saw a similar thread with no solution https://forum.playcanvas.com/t/mask-not-working-in-game/7966
Here is a project with just the issue isolated
The Scroll Menu Entity doesn’t have an Element component on it
All entities under a screen need an Element component for the rendering to work correctly.
Oh wow, I knew it was going to be something simple that I missed. Thanks @yaustar
