SpriteRenderer over geometry?

Hi,
I'm working on a 3D game.
I just need to have my sprite HUDs (small icons over characters) rendered after the geometry, without being clipped at all.
I prefer to not use a second camera.

Render queue and sorting layers seems to not having any effect. (maybe they are used for 2d only?)

Tried also

r.material.SetInt("_Zwrite", 0);
r.material.SetInt("_Ztest", 0);

I need help...
thank you

 

If check with Frame Debugger, it shows ZTest is still used,


so if want to do it manually, add

Code (CSharp):

1. ZTest Off

to the sprite shader:
