Khe Chất Liệu (Texture Slots)

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.

Chế Độ (Mode)

The slot system includes two painting modes:

Nguyên Vật Liệu (Material)

This mode tries to detect the slots from the materials of the mesh.

For the Cycles renderer, all textures (Image Texture node) in the material's node tree are added in the slots tab.

Chỉ Số Chất Liệu Sơn Vẽ Đang Hoạt Động (Active Paint Texture Index): A List view of slots. Activate a certain slot to use it for painting by LMB click on it.

Đơn Hình Ảnh (Single Image)

You can just select an existing image and painting will use the active UV layer for painting.

Hình Ảnh (Image)

Allows you to select the image used as a canvas.

UV Map (Ánh Xạ UV)

Allows you to select the UV layer for painting. (Same as the currently active UV map in the mesh's UV Maps panel.)

Kiểu Thanh Lọc Chất Liệu (Texture Filter Type)

Set the interpolation mode of the texture. This can be Linear or Closest.

Lưu Tất Cả các Hình Ảnh (Save All Images)

Repack (or save if external file) all edited images. Same as in the Image Editor.

Thêm UV đơn giản (Add Simple UVs): The Add Simple UVs does a simple cube unwrap followed by a pack operation. It's still recommended to make a custom unwrap.
