2D image above a character

Hi everyone, I want to insert a 2D image above some character to indicate that him can talk, like in FFXII:

The character can move, so the 2D picture should follow him.

I was thinking in attach some kind of Image Node (?) on the character node and using nodePath.setBillboardAxis() to face it to the camera… but this is only a guess…

Someone knows how to do this?



In this thread I see that I could use “map3dToAspect2d” and “OnScreenImage” but then I would lose the depth of the picture.

try to comment the setDepthTest/Write lines.
