Drawing in Viewport Issue

[peshang]

any idea on how to use viewport drawing methods for my code, none of drawing methods show anything in the viewport: 
DrawMarker()
DrawLine()
DrawTM()

i have 1 particle in my event and its away from 0,0,0 to avoid distraction.

It seems this is a regression that I missed...I will get it fixed in the next build.

Thanks for jumping on the fix! Looking forward to the update.
