Fix for bug #27710, 'Multires lost from 2.49 file in 2.5x' Reported by Gaia Clary. Problem was that the old multires data didn't flush changes to vertices out to the Multires structure on filesave. So, recent bits of sculpting could be lost if the multires level wasn't changed before filesave. We already had code to deal with missing multires vertex data, which simply copies the Mesh vertex data into the multires vertex data if it matches the number of vertices in the highest level. Moved this code up a bit so that we always make this copy if the numbers match up. Was able to reproduce the bug fresh in 2.49b, and confirmed that the fix works. However, this does not help if changes were sculpted on a multires level other than the highest level and saved without a subsequent level change. |
