Hi all,

https://forum.unity.com/threads/render-only-shadow.1180072/

is there a way with shader-graph make something for draw only the received shadow? every shadows received.

Thanks a lot for help!

Reading the amount of shadow that a pixel receives can be done with a custom function node. The following link describes how to do custom lighting in Shader Graph using a custom function, which should point you in the right direction: https://blog.unity.com/technology/custom-lighting-in-shader-graph-expanding-your-graphs-in-2019

 

but my trouble is don't draw the mesh that received the shadow... is it possible?

 

anybody have an idea? Thanks!

 

Well once you have the amount of shadow attenuation of a pixel, you could for example put that value through a One Minus node, and then put the result in the fragment node's alpha input. This would make all pixels of a mesh transparent, except for the ones that are shadowed.
