Hi,
Have you tried changing, softBody->m_cfg.viterations = 50;
softBody->m_cfg.piterations = 50;
To a lower value why so high?
Also cfg.kPR Softbody Pressure is not very stable.

Re: Bullet Physics Soft Constraint
Hi
Bullet physics, has many constraints for rigidbodies and softbodies, I would have a look at the demo that came with the SDK, could you be more specific on what kind of constraint you are after.

Re: SoftBody generates Uninitialised error on valgrind
Hi
I would have a look at bullet softbody demo that came with the sdk, the sofbodies in the demo a configured diffrent from yours.

Re: softbody-softbody collision issue
Hi,
This is very strange, how did setup the softbodies its difficult to tell what is going on just by the video without looking at the code.
Thx

Re: Two Outstanding Issues
Hi,
Have you tried setting the gravity value to something lower then 450.5f inside global.
Thx, hope this helps

Re: Soft-Body Objects fall apart
Hi,
I have noticed that inside your code, generateClusters is set to 64 this will create 64 individual softbody convex clusters for your object.
It seems like your object is breaking to its 64 individual collision triangular clusters.
Hope this helps
Cheers☺

Re: Softbody with metallic material properties
Hi,
Yes, just a regular softbody works fine, with gravity tuned down a little you can have a look at my previous post from awhile ago about Softbody plasticity it shows how to set up the softbody.
Hope this helps ☺

Re: Softbody with metallic material properties
Hi, The clusters in your code are set to generateClusers(64) this creats 64 individual collison clusters, setting the clusters to a lower value like 2 will create a very stiff body. Now if you want to achieve metal malubilty, thats when your object needs to have plasticity. Using a Tetrahedral softb...

Re: how to simulate ABS material for 3D printing
Hi,
Try using softbody collison clusters, genarateClusters(0) will create as many clusters as possible for the softbody, using other values will change the softness of the body.
Hope this helps.

Re: joints connecting soft body nodes
Hi,
To, simulate a spiral spring, I would use a series of soft body toruses all constrained on the Y axis, as this would be the simplest approach.
Hope this helps.
