Hi folks,

I'm trying to figure out how to set up a Spring Constraint Network correctly…I'm having a tough time figuring out how to suspend a box with Spring Constraint Relationships…I've already tried many different technics and followed a few discussions but without luck.

If some brave person look at the file, you will see the Anchor points dont follow the suspended box where they are supposed to. Also they seems attached together! And the bottom row goes to the same point at the center of the box…misery.
It's very probably not setup correctly, I'm still new to Houdini.

Any hints or clarifications about how to use anchor_id/anchor_type etc or how to make this work would be greatly appreciated!

Thanks

Arhhh! OK,I got it…I just saw that post https://www.sidefx.com/forum/topic/41203/ [sidefx.com] and after playing around with the point anchor DOP examples from the doc (as mentioned in the post) everything makes more sens now. It's actually well documented.

Here's the scene fixed
