I Have Trouble When Adjust Scale of Model - ss56806298 - 25-03-2020
1.I import an armor-man model with some cloth i want to add obi cloth on it, it seems good when i do like the video said, but when i make the scale of the model smaller, the cloth that i added obi cloth seemed smaller and position was awful. I uploaded the picture and you will know what i excactly said.[attachment=636][attachment=637]
2.You can see the cloak cannot move with model's head, i'm not sure if it can move with the head by using obi cloth or i should use animation to do this.[attachment=638]
Thank you guys.

1.- You cannot scale a cloth object, or rather, the results won't be what you expect. This is because it is mathematically impossible to fully describe the translation/rotation/scale of a deformable object using a single matrix, so the same applies to any cloth simulator.
You can however scale the solver that contains the cloth. This will post-transform the results of the simulation, as explained in the manual:
http://obi.virtualmethodstudio.com/tutorials/obisolver.html
Quote:Solvers always perform the simulation in local space. This means that translating, rotating or scaling the solver will rigidly transform the simulation as a whole.
2.- Of course you need to use animation to move the hood itself, then optionally use Obi's skin constraints to blend simulation on top. See:
