It's really a good idea
Creating c-shadows becomes easier than ever!
And not just the shadows...
I have two questions about improving
1. Simple adaptation to the inclination of the plane. In TopDown, the ratio X:Y - 1:1.
In 2.5D or a perspective scene it can be, for example 1:0.5 (0.2 ~ 0.7).
Is it possible to add the option "2.5D view" with the choice of scaling Y from 1 to 0, or something like that?
2. Option: the shadow at the bottom of the object - i.e. Shadow only within the collision mask?
if you still implementing code in your addon, maybe add condition: 'is in shadow' this could help create sneak games
