• <f> : roughness scaling factor
  • Default: 2.0 (very rarely needs to be changed)
• <i> : invert bump signal (0|1)
  • Default: 0
• <n> : interpret as normal map (0|1)
  • Default: 0
• <iu> : invert map in U (0|1)
  • Default: 0
• <iv> : invert map in V (0|1)
  • Default: 0
• <iv> : refit slope distribution for better results.
  • Default: 1. 
  • This step is time consuming but preserves details much better when seen from afar.

A typical txmake invocation for a bump map:

txmake -resize round- -mode periodic -bumprough 2 0 0 0 0 1 bump.tif bump.b2r

For a normal map:

txmake -resize round- -mode periodic -bumprough 2 0 1 0 0 1 normalmap.tif normalmap.b2r
