System Information
Operating system: MacOS (current Mojave 10.14.5)
Graphics card: Radeon Pro 570 4GB

Blender Version
Broken: 2.80 Beta
Worked: (optional)

Short description of error
Multires Modifier shows strange functionality with creases. It seems to invert the crease profile.

Sudivision Surface Creases are excellent.

Exact steps for others to reproduce the error

Default cube, in edit mode crease edges to 0.50.
Object mode add Multires modifier.
Subdivide a few times inside the modifier.

Thank You,

James

I can not reproduce this, using a cube with a subdiv modifier gives the same result.

Does this still happen with the latest blender beta?

Hello Sebastian,

Thanks for getting back to me on this. I've reproduced the error on a Windows machine and attached the file.

*if the Mean Crease is set to 1.00, everything functions as normal. If it is set to anything below (0.3, 0.5, etc.) the error occurs.

Once again if you use a Subdivision Surface modifier everything is perfect. However, if you use Multiresolution modifier instead, the creased edges produce a strange error.

Thanks Again,

James Light

This is caused by a transitional state of code, where Subdivide uses old subdivision algorithm, but sculpting and drawing are using new one: causes mismatch how displacement is being updated and propagated.
