Help Cloth not behaving as ... cloth?

[mikemikemike]

Thanks for your help! I'm running Unity 2020.1.6f1 if that helps.

The steps I followed: Installed the package. Created an Obi Cloth Blueprint. Added a mesh to the blueprint. Clicked generate. Checked the mesh in the edit view - all good. Then created a new Obi Cloth game object. It was instantiated as the child of a solver. I selected the blueprint and applied it to the cloth. Then I clicked "Play" on my scene. The cloth does not move or anything and seems to be frozen in place, and the frame rate drops very low.

I checked the sample scenes, and none of them work either. Interestingly, when the game is playing the first sample (Cloth > Benchmark) I cannot even move the flag transforms in the scene view. The transform value changes but they show themselves as if they're stuck directly in place. There is a game object in that scene called "Burst Collision World" with a script on it. When I click on that, I see a warning that says: "the associated script cannot be loaded. Please fix any compile errors and assign a valid script."

I also have Obi Rope and none of the rope samples work there either. It's as if all the Obi Materials are stuck in place.

Resolved by downgrading Unity down to 2019 version then back up to 2020! Not sure why that fixed it, but all good now. Thanks!
