Activating and Deactivating Cloth Paint marks the skeletal mesh as dirty, even if no values were painted and there is no transaction in the Undo History.

Painting Max Distance values from non-zero to zero or zero to non-zero, does not update the number of Fixed/Simul Verts displayed in the Mesh Clothing Assets Details, until a new clothing data is created/deleted.

Steps to Reproduce

Select a skeletal mesh with clothing data.

Activate then deactivate cloth paint without painting any values.

Expected: The skeletal mesh asset does not need to be saved as nothing has changed.

Result: The skeletal mesh asset is marked dirty.


Select a skeletal mesh with clothing data.

Notice the # of Fixed/Simul Verts displayed in Mesh Clothing Assets.

Activate Cloth Paint and paint Max Distance values such that the number of Fixed/Simul Verts should change then deactivate Cloth Paint.

Notice the # of Fixed/Simul Verts displayed has remain the same.

Expected: The # of Fixed/Simul Verts displayed should reflect the new painted values.

Create a new clothing data or delete a different one.

Result: The # of Fixed/Simul Verts displayed have been updated.
