Hi Erwin,

thanks for the reply. Could you give me some quick pointers on how to go around implementing it? If it is not an absolutely massive task, I would be happy to take it on.

Hi, Is it possible to get softbody on renders from p.getCameraImage? It only seems to be displayed on the main GUI window, but synthetic camera windows do not seem to show it. By inspecting the code, I found that soft-bodies are only rendered in debugDraw - is it possible to use it to get draw data ...

Thanks drleviathan, appendAnchor seems to work for anchoring softbody to rigidbody. However, it does not work for multibodies. I found a solution if anyone else is having the same problem - I made a tiny rigidbody that is fixed to multibody by p.createConstraint and then I anchored the softbody to t...

Hi, I am trying to grasp a softbody with a gripper. It seems like the easiest way to create a stable grasp would be to anchor the softbody to the gripper when a collision is detected and some pressure is applied (I believe I could figure out the details later). However, it seems like softbodies and ...

Quick update:

I have run the Friction softBody demo with 20 bunnies initialized with cluster collisions and friction work as expected. Sorry for a misleading suggestion. Any other ideas what might the problem with grasping?

Hi drleviathan and Erwin, thanks for awesome responses. My timestep is already fairly small (1/240.). I tried halving it but it did not help. Increasing the margin makes the tunnelling even more likely because the force pushing the cloth from inside the gripper is stronger (at least in my case). I h...

Hi, i am trying to us bullet as a simulation tool for Reinforcement learning on manipulation of simple soft bodies. I adapted a grasp example to try picking up a piece of cloth, but it seems like the gripper just goes through the cloth, even tough the collision is detected. Any ideas on what I could...
