DisplayConduit - Depth Testing - Ignore Ground Plane?

Hello,

In my custom display conduit I am drawing sprites that I want to utilize depth testing and not show when behind objects, however, I want them to still show on top of the GroundPlane, is this possible?

What DrawForeground gives me with DepthTesting = True:

image626×582 18 KB

What DrawForeground gives me with DepthTesting = False:

image647×601 19.4 KB

What I need it to look like:

image
image589×545 58.7 KB

Relevant code:

def DrawForeground(self, e):
    if e.Viewport.Name != UI.viewport.ActiveViewport.Name:
        return

    sprite = UI.sprite_icons.get('sprite', None)  # Get the cluster sprite bitmap
    if UI.cluster['count'] == 1:
        if sprite: # Draw Sprite bitmap representation of icon
            e.Display.EnableDepthTesting(False)  # Disable Depth Testing so that the next elements that get drawn to through everything
            e.Display.DrawSprite(sprite, UI.cluster['center'], UI.sprite_size, False)

I would turn off the ground plane but I need to display it so that’s not an option.

Thank you all for any pointers you can provide!
