FIXED:BSolver COMP Actor COMP and Object CHOP

Bugs
1

Hello,
having these three nodes in a network, with the object CHOP referring to an actor COMP creates a cook loop.

I feel like the object chop would be a pretty good tool for using in the context of the bullet feedback CHOP parameter so I’m inclined to think this may be a bug.

The demo file is on 1200 but I initially found it on the alpha build.

Thank-you

For simulation feedbacking, and more generally, to get the simulation data into CHOP-space, you should use the Bullet Solver CHOP. There’s a few OP Snippets showcasing the workflow.

Hi Eric,

The cook loop also seems to happen if the object CHOP references a Geo COMP unrelated to the simulation.

In my use case I am using the bsolver CHOP while the object CHOP does some calculations in relation to other (non actor) geos in the network.

edit: sorry went a bit fast there and didn’t check the full error log. I still get a cook loop even without the object CHOP now. I’ll look into it a bit more.

Hi again Eric,

In regards to my previous post. My mistake was that the bullet solver COMP loads with an error regardless of anything else in the network .

As for the bullet solver CHOP I’ve found how I can replace the object CHOP in my network.

Thank-you for your help!

Is the cook loop warning still there and an issue? I’m not able to reproduce the warning on start-up that you mentioned.

Hi, yeah I’m getting that error on 12000.

oops spoke too soon again regarding the bsolver CHOP solving my issues.

Using a bsolver CHOP requires that I make my geo COMP an actor which adds a bit of complexity to my simulation regarding collisions etc.

In this case I can use a parameter CHOP to get the txyz parameters instead but it does seem that the object CHOP has some weird behavior when used in-line with the feedback CHOP parameter of an actor.

Thanks, I can reproduce the cook loop issue now. I’ll take a look into it.

The cook dependency loop bug will be fixed in the next official build we release: 2023.12150+. Thanks for the report.
