Materials

- Import DAZ Materials: Load materials from a native DAZ file to the active mesh.
- Save Local Textures: Save copies of all used textures in a local textures folder, and change all paths to relative. The blend file must be saved first.
- Resize Textures: Replace selected textures with lower resolution copies to conserve memory. Local copies of the textures must have been saved first.
- Merge Materials: For all selected meshes, merge materials that are deemed identical (same textures etc.)
- Change Colors: For all selected meshes, change the color of all materials with textures.
This section changes some material settings. Everything can of course be changed in the compositor (for Cycles materials) or in the material and texture contexts. However, meshes imported from DAZ Studio often have many materials - a Genesis 8 character has sixteen - and updating each of those manually would be tedious.
More tools for handling materials can be found by enabling the Material Tools feature.
FIXING BLENDER UNPACK. note by Alessandro Padovani.
As noted by CookItOff the blender unpack tool has issues with daz textures because it can't unpack the content folder path. A workaround is to first save local textures with diffeomorphic then pack/unpack.
