I am trying to create a X-COM like hp bar for my enemies with single sprite representing each health point.
To do this i used a 3D Sprite node as a billboard with a texture coming from a viewport. Inside the viewport there is a grid container where I instance each health point.
Everything works except that there is some weird pixel smoothing that hides/shows some part of the hp sprite resulting in a flickering effect as the camera moves and it just looks ugly when the camera is stopped.

How it looks:

The complete sprite:

Is there a way to tell the engine to always draw the complete sprite?

I don’t know if this addresses your scenario, but I found that increasing the space between the flickering nodes can solve this issue. My case was simpler, I used a plane with a texture, pressed up against a 3d box shape - - but I had noticed flicker and adding a little distance solved it
