Greetings,

We're trying to optimize our characters for UE5 as much as possible, but we've run into issues with how materials are handled, there are simply too many.

The main problem is with the material merging system. We’d like to merge the textures of the ''CC_Base_Body'' while keeping the head separate to preserve texture density and resolution. However, when using the current tool, everything on ''CC_Base_Body'' gets combined automatically without any regard to the space it takes on the UV sheet, resulting in huge nails, small face, the list goes on. It would be extremely helpful if we could select which components to merge, rather than being forced to merge them all. Even better would be the option to fully customize the resulting UV layout.

Another problem is that we would like to see some consistency with the UV unwrap results when merging the mats. After running the merge, if we close the project without saving, open it up again, merge with the exact same settings and you will get a different UV layout than you did the first time. Since the results are different every time it means that you can't use it for baking multiple versions of the same materials. We would like to use the same maps for different NPC characters and so it's just not possible to have the same result every time in each different scenes and the different characters.


Thanks for considering adding this feature in future updates.
