World widget on Screen Space

Unreal supports only world or screen space but i need symbiosis - widget should be affected by environment, i mean that I want widget to be partly hidden if there is a wall for example. Same idea as widgets in Lineage II

You can make world-space widgets to always face the screen and be of the same scale regardless of distance
However, it would be affected by resolution percentage and not always be pixel perfect

The problem is in render quality for world widget
