sop solver question

[catchyid]

Hi,

I want to control a RBD translation using RBD Solver, and control the object rotation using SOP Solver.  I used Multisolver, made RBD Solver the first input and SOP Solver the second. Inside the SOP solver I could not find a way to access the translation/orientation of the RBD as whole. My questions:

-SOP Solver is not meant to change objects position/orientation, right? It has access only to points

-What is the right way to achieve my goal? Should I use Script Solver instead?

Thanks

You can add a "Transform" node after the "dop_geometry" node and do the rotation with that. Would that help?

Hi bonsak, unfortunately it does not work. I did it and nothing happened.

I "think" that the SOP solver is only concerned about point/vertices/... processing, however changing the entire position/translation of the DOP object is not its job. BTW, let's say instead of adding "translate" node, we add "Attribute Wrangler" node and write something simple such as @P += @N, now this works fine...

When I check the geometry spreadsheet, I see "Position" data, I think somehow I need to overwrite the rotation values in here. Maybe a script solver would do it...

This is much easier if you use RBD Packed objects. Then, each RBD object is represented by one point, and manipulating it in a SOP Solver as one object is easy.

Thanks rich_lord, it does work  Thanks again...
