Bullet, ConeTwistConstraint, strangle wobble effect

[Juzwa]

Hi, 

 

I'm struggling with it since yesterday and I don't know how to fix this. I get this strangle wobble effect on my Cone Twist Constraints:

 

 

These are my Cone Twist Constraint settings, pretty default:

 

 

I have 3 constraints:

 

1) glue to keep things together

2) hard to keep different structures together

3) cone twist to make the sim more natual, and  to break into bigger chunks.

 

I have a connected sop solver to my constrain network(cone twist). And an atrribute wrangle connected to relationship_geometry, with this expression:

if (@angle>0.2)
    removeprim(0,@primnum,0);

The angle in this constraint is barely going over 0.3. 

 

Mainly I was playing with this expression since this is what is responsible for breaking the Cone Twist. When I set the @angle to sth small like 0.05 the wobble is gone, but the cone twist breaks ones sth hits the wall and It doesn't look nice. With higher values (@angle), the chunks are nicier, but there is more wobbling effect. I tried to combine this expression with @torque however I didn't see any differences.

 

So i think this is about the setting of the constraint itselt. I'm playing with values but can't fins anything right. What is the main cause of this wobble?

well , it is hard to tell , so if you could include a hip file to look at this will be better

OK i forgot to share the file, here it is:

OK , i will look at it when i finish my work

Hi , 

i have seen your file and i the reason of jiettring from two parts 

the first one the wood

second from the big scattering points in your con digital asset 

Also i edit your sopsolver code for the Hard con one by adding :

if (@torque>@breakTorque)

    removeprim(0,@primnum,0);

 

 

iv made for you some changes look at them, They are in red color nodes 

i hope it is helpful
