[Closed] Thinking out-loud… Maxscript Set-extension tool?

Just before I set out and make this, has anyone seen anything similar?

Script will fire rays from the matte painting project camera, detect areas occluded by other objects, mark them red, then go through using a moving camera and where there’s any underlap reveal it marks this as say Green…

Then render out maps from mattepainting camera so you could see where you need to make set-extensions…

Thinking best way to do this would be to use Vertex Colour…? But this would need a fair number of vertices to work propperly… And therefore be quite slow…

Oh and to make it even harder it’d have to work with Opacity Maps as well…
