This is a program to generate normal-, spec- and displacementmaps from image textures in one go. It supports stack processing and a few other nice features, but has some rough edges and is still in development.


See the releases section. Usually there are Windows (32 bit) and Linux (64 bit) binaries available on each release.




  • Fully multithreaded with OpenMP, will use all available CPU cores
  • Keep Large Detail (see below for details)
  • Fast and easy way to create normal, spec and displacementmaps

Keep Large Detail

One of the things I hate about classic normalmap generators is how they handle large image textures: usually the normalmap is unusable due to fine detail and the whole information about "large detail" (the overall curvature) is lost.

This is a large texture generated the classic way: kld_disabled

When used in a rendering, it will look like this: kld_disabled_render

What the feature I called "Keep Large Detail" does is that it blends a downscaled version of the image over the original image, thus retaining the overall curvature information while still showing fine detail: kld_enabled

Rendered, it looks much better: kld_enabled_render

Planned Features

  • Ambient occlusion maps
  • And the issues marked as enhancement
You can’t perform that action at this time.
