Hi, "they have very little documentation for a fairly complex product." Not sure what you mean, documentation is extensive and detailed: https://obi.virtualmethodstudio.com/manual/7.0/obisolver.html It goes over general asset architectural design: https://obi.virtualmethodstudio.com/manual/7.0/bigpicture.html Global simulation parameters: https://obi.virtualmethodstudio.com/manual/7.0/obisolver.html Collision detection: https://obi.virtualmethodstudio.com/manual/7.0/collisions.html Setting up a softbody: https://obi.virtualmethodstudio.com/manual/7.0/softbodysetup.html Using the blueprint editor: https://obi.virtualmethodstudio.com/manual/7.0/softbodyblueprinteditor.html Skinning meshes to a softbody: https://obi.virtualmethodstudio.com/manual/7.0/softbodyskinner.html Even how the engine works internally: https://obi.virtualmethodstudio.com/manual/7.0/convergence.html And lots of other topics: from scripting to troubleshooting, there's over *50 pages* worth of documentation with animations, images, etc. If you'd want more details about a specific use case or have any questions, feel free to ask! "I use Obi Softbody and Obi Rope, and I can't figure out how to link them together, since there's not a word about interaction in the documentation." Interaction is automatic, no need to do anything: just place a rope and a softbody together in the same solver and they'll interact since everything is made out of particles, and particles colllide with each other by default. This is mentioned many times troughout the manual. If you want to "link" them together as in attach one particle of the rope to a particle in the softbody, use a ObiStitcher component. Here's the manual pages regarding it: https://obi.virtualmethodstudio.com/manual/7.0/stitcher.html https://obi.virtualmethodstudio.com/manual/7.0/stitchconstraints.html let me know if I you need further help,

Thanks for your review! I am indeed a physics simulation enthusiast, glad to meet a likeminded fellow :)

Hi there! Surely we'll be able to help! please write to our support email and/or forums and we will work with you to get it up and running. Setup for all Obi assets is identical, so if you've successfully set up any of the others as you mention then you must be missing a small detail to get ObiSoftbody working.

Hi, Thanks for your review! Softbody simulation in general is a *very* advanced topic, and Obi in particular requires prior knowledge about both physics simulation and C# programming to be used in an effective way. This said, we'll be more than glad to help you if you write to our support email and/or forums.

Hi, just hit "Bind Skin" in the ObiSoftbodySkinner component. This is because meshes imported from older Unity versions will have their vertex order changed in newer versions, so the serialized softbody data is no longer correct. Drop us a line if you need any help! :)
