Description

Hi,

I am trying blender 2.80 26-01-2019 25772c9e1d2d
Just also tried 2019-01-31 8c8979067490

I have a project that was created in 2.79 and tried opening it in 2.80 and the cloth are all stuffed up.
One of the cloth works fine but the other is not really moving. I tried rebaking in 2.80 but it appears very broken.. (Cloth stays rigid in my project rebaking)

It might be something to do with having the cloth copy location of a bone. I am not 100% sure

I have created two tests for you to look over. Both Created in 2.79
test1.zip two soft balloons moving and shaking
test2.zip One with a sheet going over the box

in blender 2.79 both projects play fine and bake fine
in blender 2.80 both projects fail at baking.. the mesh goes crazy and jumps all over the place.
in blender 2.80 it seems to be the object constraint is moving every subframe as playback kind of mimics this statement. for the tests..

I am under the impression that the problem above is similar as my Main Project problem.
The project was too large to share.. sorry.. I hope my test files above help to solve the problem for me.

@Sebastian Parborg (zeddb) sorry, looks like phab does not warn when you are saving updated description, that someone else changed the task in-between ;)

This is also probably same general issue as T60451

I Can Verify that the New Nightly Build of 2.80
the cloth tests above are solved.

My Main project is also working properly now.
Thanks so much for the effort guys..

Cheers
