Hi all! I am trying to figure out how to utilize the APEX sim nodes in the graph to create a Float counter and index it per frame. My goal with this is to have a lightweight value accumulating per frame that could drive certain rig properties when animating and have them update quickly in the viewport.

I have made a simplified example based off of the included Ragdoll solver APEX node, attached below. There is not much documentation on how to do this, but I believe it is based off of DOPs. There is also no "Get Sim Subdata" APEX nodes, but there are "Get Sim Geo" nodes, so I am saving my counter to geometry as a detail attribute and retrieving it that way. However, after running it through a "Eval at Time" node, Getting the detail attribute is unsuccessful, and returns a value of 0 in the Boolean. Can anyone help me figure this out?

on your sim_evaluatetime1, put this into datapath parm:

tamte
counter_object/Geometry

Ahhhhhh Thank you so much!!! That makes so much sense, I have to get the Geometry attached to the DOP object I made a custom name for. Thanks!
