Capture shadows like in Blender

General
1

I’m looking for the way to render out shadows from 3d object in scene using Godot .
For demonstration I made this short in Blender to show what I mean :

Ok why in Godot not Blender ?

  • ultimate goal is add it into spritesheet generator to combine unshaded and shaded layer together
  • unshaded 3d model for sideview or isometric 2d game
  • shaded this be 3d shadow, particle, effects turned into 2d sprite along unshaded frame

current workflow of spritesheet generator using unshaded material - short demo below

I hope this was detailed enough , if not please ask question .

You want to render cast shadows only? Set the Transparency property of casting mesh instances to 1. They’ll be invisible but still cast shadows.

yes that what I’m trying to do .

where can I find this casting mesh instance ?

Casting mesh instance is any mesh instance that casts shadows. The transparency checkbox is right above cast_shadows checkbox in the geometry instance section of node’s properties.

Have tried to use it , but unfortunately can’t achieve only shadow without some visible mesh to project it on .

Cast on white surface, and use as alpha (inverted).

You can also use shadow_to_opacity in receiver materials’s shadow properties.
