This section explains the Polygon Surface option.
[Example 1]
Texture size (X,Y)=(32,32) pixels
Length of one side of mapped polygon = 1 Softimage unit
Pixels per unit = 25
Maximum Slice Size option is OFF
Original texture: (X,Y)=(32,32) pixels
Output texture: (X,Y)=(32,25) pixelsSince Pixels per Units is set to 25, a texture of (25,25) pixels should be output, but on the Saturn, the X (horizontal) size of the texture must be a multiple of 8, so it is 32 pixels. It will be.
[Example 2]
Texture size (X,Y)=(32,32) pixels
Length of one side of mapped polygon = 2 Softimage units
Pixels per unit = 32
Maximum Slice Size option is OFF
Original texture: (X,Y)=(32,32) pixels
Output texture: (X,Y)=(64,64) pixelsSince the length of one side of this polygon is 2 SI units and Pixels per Units is set to 32, a texture of (64,64) pixels will be output.
[Example 3]
Using the same data as in Example 2 above, try outputting with the Maximum Slice Size option set to ON and (X,Y)=(32,32).
Output texture: (X,Y)=(32,32) pixels
