Subject: Soft constraints evaluating differently when their nulls are invisible

Hey guys,

It's been years since I used soft constraints but for what I'm doing right now they are just what I needed. I thought about trying to do them with ICE or a SCOP, but it seemed like reinventing the wheel for no reason.

Now I'm finding that if I show only the geo of my rig, the soft constraints appear to evaluate differently. What gives? :p They look mostly right, but tamer.

I know sometimes invisible objects don't evaluate, but they are driving constrained solid pieces so I figured they should be evaluating at all times regardless because of this.

Any tips before I go reinvent the wheel?

Cheers,

It was off but turning it on made no difference.

Odd, works all fine here - but we are on 2011 SAP SP1 - not sure if it has changed for later versions.

I repro this too.
I think this has been around since day 1.
To counter this, I usually soft constrain a cube instead of nulls and then hide all it's polys.
Probably the center must exist in the viewport for proper eval with soft cns.

My test scene:

Click play and unhide the hidden object to see the difference.

Good trick! Thanks for looking into the problem, Manny. :)
