Question

I’m trying to get Material Override to display a shadow the same way Material Overlay does. This is specifically for a 2d texture as a Sprite3D.

Project with Material Override, and no shadows: GitHub - michael-conrad/GamedevTvActionAdventure2.5d_RPG at 5c1a1f65610d2a378e66f4b6407980865a3d01db

Scenes: Player and Enemy, with shader applied to …AnimatedSprite3D

Switching to Material Overlay and the shadows start working?

Is this just not possible with Material Override?

For the project I’m working with.

I think it is working.

Had to rotate the sprite-3d 180 degrees, so that the overlay shows up in front and not in the back.
Switched to MaterialOverlay
set FLAGS: double-sided = false
set FLAGS: alpha cut = Opaque Pre-Pass
set GEOMETRY: Material Overlay with shader
set GEOMETRY: Cast Shadow = Double-Sided
Invert the Flip() true/false values to match the new Sprite3D rotation.

Makes me think the camera is pointed 180 degrees in the wrong direction.

I now am getting shadows as well as the shader working in my test project.
