UV-groups

UV-groups influence the process of UV-mapping.

The main purpose of UV-groups is to group cuboids together so that they are mapped to the same spot on the texture. Using UV groups can help reduce the texture size when the model has many identical parts.

UV-groups also let you change the appearance of generated textures to your preference. This can be useful for creating distinguishable look for UV-group members. You can create some fairly advanced textures with it, but it’s usually better to create textures manually.

Creating and removing UV-groups

UV-groups are added / removed using the Mcblend UV groups panel from the Scene Properties with New UV group and Delete this UV group buttons. You can also export and import UV groups by using the Export UV group and Import UV group buttons respectively.

Adding objects to UV-groups

Adding objects to UV-groups is done with the Set the UV group button on the sidebar. You must create at least one UV-group in order to add objects to it.
