[Max] General Discussion / It was an easy task in 2006 to modify shadows in Max...

As a former old Max user (standard  renderer, version 8, circa 2006), I was discussing with a friend of mine, an unsophisticated Corona user, about how simple it was - at that time - to modify shadow colors using render elements and an alpha channel; I pointed out to him that in order to insert the render of a building, made with a white sun (so no hdri), in a photograph with blue ambient light, he would at least have to retouch the color of the shadows in photoshop. Having answered that he doesn't know a method to do it, I searched a bit in this forum, and it seems to me that there are functions called render pass, shadow catcher, vfb, cshading_shadows, etc but can be used only on direct shadows; moreover it would seem to be an evolving topic in time and I can't understand the current state of possibilities. Could you give me a tip or direct me to some recent article or other media on the issue?
