Glue constraints break and reappear in next frame in SOPs

Recommended Posts

Hey, I've been learning Houdini whilst at university and I've been using a pluralist tutorial to help me along the way with a certain piece of work. The problem is that I'm using version 16.5 and the tutorial was using 16.0.

This has created some problems with using SOP's to delete the constraint network.

I've uploaded the file below and have coloured the nodes to where I feel the problem lies.

It would be much appreciated if someone could help me fix this problem, Thank you.

your file works for me in 16.5.405 I don't have other 16.5 builds installed to compare

however if for you the constraints reappear check what values the expression in constraintnetwork1/Overwrite With SOP evaluates to

you want it to be 1 on first frame of the sim and 0 on all the others, to bring the constraints just once and then allow them to be modified in dops from then on
