Make UDIM Materials

Once all geografts have been merged with the mesh, we can now convert its materials to UDIM.

With Aiko selected, press Make UDIM Materials.

• Fix UV Tiles: Attempt to automatically fix the UV tiles, as an alternative to the Set UDIM Tile tool.
• Merge Materials: Merge materials and not only textures. If enabled, some information may be lost. If disabled, the Merge Materials tool must be called afterwards.
• Active Material: The material used if Merge Materials is enabled.
  • All: Select all materials.
  • No: Deselect all materials.
  • Skin: Select skin materials.
  • Skin-Lips-Nails: Select skin, lips and nails materials (default).
• List of materials that will be replaced by UDIM materials.

The textures nodes are now changed like this. A "T_" has been added in front of the texture name, the extension is changed from Clip to Repeat, and the source is changed from Single Image to UDIM Tiles.

In the UV editor, we can now see the tiles of the tiled texture. Notice that the tile labels equal the old material names.

If the Merge Materials option was enabled, all selected materials are removed except the active material. This may lead to some information loss if some of the original materials was different from the others.

Otherwise we need to Merge Materials with the tool in the Materials section. In this case we usually need to enable the Ignore Strength option, because the bump distance depends on the area covered by the material and is usually different for the ingoing materials.
