intrinsic Posted August 19 Share Posted August 19 Hi there I am having a tough time understanding why my constraints are rebuilding themselves in dops when I break the constraints in SOPS. I am deleting the constraint primitives by a simple color attribute in sops . I don't know why it is rebuilding itself randomly on each frame ? When I delete it within a sop solver in dops, i don't get any issue.... Can someone please explain why this is happening. Thank you break_con_in_sops_question.hip Quote Link to comment Share on other sites More sharing options...

The SOP context recooks every SOP in the network for that frame only - no information from previous frames exists, so the system is not aware your constraints were broken. SOP Solvers, on the other hand, provide access to previous frame information which allows you to keep track of changes that have happened (such as deleting constraints in your case). It is worth looking at the "Footsteps" example file linked in the Solver SOP help information to reinforce the idea of how this is working. Hope that helps 1 Quote Link to comment Share on other sites More sharing options...
intrinsic Posted August 19 Author Share Posted August 19 @Librarian @ryew Thank you both for the informative examples and explanation. It makes sense to me now. Cheers Quote Link to comment Share on other sites More sharing options...
