Transparent proxy material?

Hi!

I need to render my custom component (like Arrow Component) in the viewport with some transparency.

But seems alpha value of FLinearColor is not working for FColoredMaterialRenderProxy. (You see similar similar - on the Arrow Component when change material alpha. The arrow will stay solid.)

The question: I need transparent proxy material for my custom component. Can you advise me please?

Thank you!
