Change polygon color when collision detected

Hi, this may be extremely complicated,maybe not!

I've looked into Xpresso solutions but I seem to be spinning my wheels.

Essentially I'm trying to visualize interference detection. When an object passes through another object, I want just the intersecting polygons to change color (not the whole object). The movement would be animated via timeline (not gravity).

It seems like a ghost tag should be involved? I can't seem to connect the dots.

Any ideas?

Thanks in advance.

Have you tried using the Collision node in "Object" mode and inserting selection-tags?

Niklas, that's PERFECT.

If you feel like explaining, would you mind giving a breakdown of what you did? I understand the structure of the Xpresso, but I don't quite understand how it knows which material to assign.

Select the Collision Node and in the Attribute Manager,
right click a relevant parameter -> Show Help.
There it is fully documented

The proximal shader shader might be useful too.
