Transferring smart materials over to a new mesh creates errors?

christopheduron

Hello everyone,

I have been painting a character of mine and after creating a base layer i wanted to make some changes to the base mesh before i continued. I made my changes in 3dsmax, then imported it in SP1. Before i did this i created smart materials of every material i had created so i could transfer the painting i had done earlier onto my new mesh.

However when i do this it changes a little even though the mesh itself and the UVS haven't changed at all. Behold:

The new mesh

How it was supposed to be


Masks seem to be doing something weird aswel?


How is this possible? It does this for almost every mesh aswel, not just this belt. Is there a better way to make changes to your base mesh without losing the painting you've done?

My guess is that you used information on your mask that rely on the mesh geometry, in this case probably because you used the Polygon Fill.
Try to use ID maps and similar colors instead to transfert masks more easily between objects.

Yea, i used polygon fill alright. I still find it strange that it screws things up since the mesh geometry didn't change at all for most of my meshes and all paint layers seem to have gotten a bit of an offset.

Did you rebake your maps? If you changed the topology then your NM will be broken.

The part that was changed didn't have any bakes to begin with, i just textured everything in substance. The belt in the picture for example stayed 100% the same, but it creates errors when i add the same smart material to it.
