I have a sim I'm working on where coins are falling into a box. I have a low res coin and a high res coin and want to replace the low res coins with the high res coins for the final simulation. How would I go about simming the low res geo with the high res coin displaying in the final result? This is my current main setup.

want to say i scrapped this method and went ahead and did a points from volume and applied a rigid body setup to that instead in the dopnet. its much cleaner but still not getting the high res pieces to be placed on the low res coins

You probably want to use one of the copy nodes instead of transform pieces since it looks like you only have one coin model. Your current setup looks more like if you had a fractured object with 100 unique pieces with their own names to work with the transform pieces.
