Back
the difficulty lies in the fact that zpics are not image, it's the zbuffer and
the values
go from 0 to as much as minus 100,000, which you want to compress in a smaller
range.
The first step is shaving the range that you don't need with the pixel parser.
First load the .Zpic in the compositor. Then add a Pixel Parser node.
type in the formula : 1-((1-pixel)*100000)/a1
Now, using the "a1" slider you can narrow down the ZPic around 0 to 30 (the
distance in Softimage Units). Type in a greater value if appropriate.
You can fine-tune the contrast by adding a Luma Adjust node.
A file output node to save the final .pic file
