I expect AlwaysOnTop to also control if the adornment is always visible whether or not its geometry is occluded (which is how AlwaysOnTop works in the rest of the engine). However, it does not do this – as you can see in the screenshot, I am using a cube-shaped Box handle adornment but it’s partially occluded by the Baseplate regardless of the AlwaysOnTop property.
There is also a related lighting issue, which is that it seems like AlwaysOnTop is doing something different than what it usually does. When AlwaysOnTop=true, the color gets a lot brighter than what is specified by the Color Property, and with high value colors it has bloom. This is confusing because AlwaysOnTop=true is usually about removing all extra lighting-related effects, but in this case it’s adding them. Sp when AlwaysOnTop=false, the adornment’s displayed color is often closer to its Color property.
This is a problem with all the adornments as far as I am aware.
Box on the left has AlwaysOnTop=false, box on the right has AlwaysOnTop = true. Color used in this screenshot is 0,0,255.
