The combination of images associated with UV maps is called “slots”.
Selecting a Paint Slots or Canvas Image will also display the corresponding image in the Image Editor.
- Painting Mode
The slot system includes two painting modes:
- Single Image
You can just select an existing image and painting will use the active UV layer for painting.
Allows you to select the image used as a canvas.
- Create a new image.
- UV Map
- Allows you to select the UV layer for painting. (Same as the currently active UV map in the mesh’s UV Maps panel.)
- Texture Filter Type
- Set the interpolation mode of the texture. This can be Linear or Closest.
This mode tries to detect the slots from the materials of the mesh.
For the Cycles renderer, all textures (Image Texture node) on the material’s node tree are added on the slots tab.
- Available Paint Slots
- A List view of slots. To activate a certain slot to use it for paint a just LMB click on it.
- Save All Images
- Repack (or save if external file) all edited images. Same as in the Image Editor.
