Trying to fix the object

[josemendez]

Hello, Thank you for your reply! I'm currently using a hand to grab the obi softbody to obtain several information of grasping, but now it seems that even if I remove the gravity in the obi solver, the object will still move if I attach a force onto it. So I intend to keep the deformation of the surface of softbody, like depression of the barrels in the sample scene, and also fix the object so that it cannot move or rotate because of the force. I hope I made it clear this time... Again thank you for your help!

Hi!

Not much clearer really, what I tried to explain is that “moving” and “rotating” aren’t well defined for deformable objects (unlike for rigid objects). If you squash a cube flat on the floor, has it moved down? Or just deformed? it depends on where its center (pivot) is, right?

I assume that by “center” of the object you mean some arbitrary particle or particles of your choice, in that case you can just use an attachment to keep that particle(s) fixed in place. See:
