    hey unity pros . how can i make shadow catcher in unity ? i.e i want the shadow of an object to project on a transparent cube and the cube should be invisible on my scene.

    (like we use hdri backplates on blender and make a shadow catcher to get shadows in to . i want the same in unity )


    i have no coding skills , hope you may say the easiest way.

    Just to be aware, you will not make any game in Unit, with 0 programming skills.

    As far as I'm aware, you actually can't do that easily, because a shadow is not an object, but instead an absence of light.

    This can be somewhat solved by writing a custom shader. Which requires some programming skills...
