Check the scales of objects leading up to the panel. They also affect the scale.
By "leading up to the panel" do you mean that in the following heiarchy, all of the items parenting "Sub Panel" should also have a scale of 1? what about their child items (ie. a button's background and label)? Also 1,1,1?
InventoryPanel
-->Background
-->ButtonCancel
-->ButtonAccept
-->View (empty thing with my own script)
-->-->Scroll Anchor
-->-->Sub Panel (Clipping UIPanel, UIDraggable Panel)
-->-->-->Table (UITable)
I've tried this but unfortunately it didn't have any effect.
What I'm seeing is that I have 4 items in this table and as soon as the top one is about to be clipped, all of the items disappear. On the bottom side of the clipping panel the items are able to pass through that below and the clipping fails, but they don't disappear.
What are some other things one could screw up that would make clipping stop working. Maybe I've done something insane in script?
