When texture slicing (dividing into multiple textures) a single texture mapped to multiple polygons, this option is calculated based on the UV coordinate values of the texture rather than the size of the polygons. Desity Factor specifies the ratio of the resolution (number of pixels) of the original texture to the side of the rectangle closest to the shape of the target polygon.
If Desity Factor=2, the texture will be output so that the texture has twice the number of pixels on one side of the rectangle closest to the shape of the target polygon.
[Example 1]
Texture size (X,Y)=(32,32) pixels
Density Factor = 1.0
Maximum Slice Size option is OFF
Front view (red numbers are polygon numbers)
Original texture: (X,Y)=(32,32) pixels
Output texture [polygon 0]: (X,Y)=(24,10) pixels
Output texture [polygon 1]: (X,Y)=(16,21) pixels
Output texture [polygon 2]: (X,Y)=(24,21) pixels
Output texture [polygon 3]: (X,Y)=(16,10) pixels
[Example 2]
Texture size (X,Y)=(32,32) pixels
If Desity Factor = 2.0.
Maximum Slice Size option is OFF
Original texture: (X,Y)=(32,32) pixels
Output texture: (X,Y)=(64,64) pixels
[Example 3]
Texture size (X,Y)=(32,32) pixels
Length of one side of mapped polygon = 3 (X direction) x 1 (Y direction) SI unit
Density Factor = 1.0
Original texture: (X,Y)=(32,32) pixels
Output texture: (X,Y)=(32,32) pixels
