SOP Solver / Constraint Solver / Breaking Constraints

Recommended Posts

Hi everyone!

I'm relatively new to Houdini, and I came across a tutorial which explained the bullet solver for H13. I am trying to recreate the effect that he got at 53:15, where primitives were deleted from the constraint network when a force over a certain threshold was applied.

tutorial: 

 

 

As I understand, the SOP solver was changed in H14, and I therefore don't have the object merge node that he has. I downloaded the example HIP file and copied his node into my own project and managed to get it working, however I'd like to know how it actually works, rather than just copying and pasting!

The data that the node is bringing in, is as follows:

`stamps("..", "DATAPATH", chsop("relnode") + ":Relationships/" + chs(chsop("relnode") + "/relname") + "/" + chs(chsop("relnode") + "/relationship/dataname") + "/Geometry")`

This isn't like anything I've come across so far in houdini - if anyone knows what this means, and could explain it I'd be very grateful!

Best,

Stephen
