# Sample Node Group IDs List of affected nodes (ordered by priority): * Sample Nearest Surface * Geometry Proximity * Sample Nearest * Merge by Distance * Sample UV Surface ![image](https://hackmd.io/_uploads/SJKQI6yo6.png) Generally need two new inputs: * Group ID: Splits the geometry into separate groups. Is evaluated on the input geometry. * Sample Group ID: Which group to sample in. Comes from the context. (* Only exception is the Merge by Distance node, which only needs one Group ID input)
