3D Compositing
13
Moving the image to a position of 25, 25, 25 displaces it by 25 units from the
group’s
origin in all axes. While the image’s apparent position relative to the world is 75, 75, 75,
its Position values in the Inspector are 25, 25, 25 because its position is always relative
to its parent.
Rotation values are also relative to an object’s parent.
Important:
World and view transforms are limited to the HUD and onscreen controls;
all transforms made in the Inspector are relative to an object’s parent’s space.
Layer Order and Depth Order
When compositing in 2D, the Layers list shows the layer order, which determines which
objects appear on top of other objects. Objects that are higher up in the Layers list
appear on top of objects lower than them in the Layers list.
