Jeroen Bakker (jbakker) lowered the priority of this task from Needs Triage by Developer to Confirmed, Medium.

Seems to be missing/incorrect implementation in BKE_mask_copy_nolib Code assumes that the layers are structured identically, but the DEG copy has no mask_layers

Brecht Van Lommel (brecht) raised the priority of this task from Confirmed, Medium to Confirmed, High.Jul 17 2019, 3:59 PM
