Patch 1.2 and Tutorial video

Second voting Patreon voting poll concluded some time ago and I bring goodies. Results shown that users want to improve roughness map, which was admittedly
the weakest part of ModLab. To improve it I need some extra data, specifically curvature. This version of ModLab let you generate curvature from Normal map and use it to improve Roughness map. On top of it even if you provide your own Roughness map you can use new data to add some details to it.

As seen here:

Curvature itself is quite powerful information. For that reason if Curvature is generated it will get saved (unless exporting for WTF:ZF format) and can be used in any 2D editors. Red channel contains grey mid point information, green isolated edges and blue isolated cavities.

I made quick tutorial about using ModLab for sprite:

Change log:
-New Roughness processing!
-Large amount of features relevant to roughness
-Curvature from Normal map
-Wrote bypass for PNG compression
-Rare bug when part of saved image is missing should be fixed
-Better GUI separators

Big thanks to all Patrons. If you want to support ModLab, want to be able to vote regarding future development or simply want access to new version slightly sooner then please visit Patreon page:

So user had issue with windows open file dialog and asked for another method of loading files. Alright then, patch v1.1.1 is out and you can now load textures by drag and drop onto load file buttons. Also fixed one possible crash that I accidentaly discovered.

About This Software

Modlab is not an image editor. ModLab is a free tool that can generate normal maps in a realtime deferred rendering environment. It was initially created as an asset previewing and mastering tool for the game Wayward Terran Frontier which means it stands out among other content creation utility programs by featuring a full hardware rendering pipeline for previewing results in realtime.

Modlab can generate high quality normal maps without 3d geometry.

ModLab is completely free but you can support development at

The Modlab project has 3 core goals.

  • To provide entry level graphic designers an alternative way to create difficult assets such as normal maps and specular/roughness maps.
  • To provide professional graphic designers an ideal environment for fine tuning their art and exporting ready-to-ship assets.
  • To serve as a test bed for new experimental content generation techniques and algorithms. i.e. cool stuff we want to play around with.

Depending on reception and feedback Modlab may grow to become much much more. We would like to continue developing Modlab in coordination with the community. Our goal is to have the product remain free and supported by donations, and we will be hosting community polls to decide the direction of future development. Features such as procedural backdrop generation, support for other rendering and post-processing pipes such as Unity or Unreal, and 3d model previews of assets are all on the table.

Key features:

  • Generate a normal map from a diffuse map using advanced image processing and analytic techniques
  • Generate detailed normal maps from height maps
  • Combine normal maps with custom blending parameters
  • Create a horizontal profile for a normal map using the curve editor
  • Clean up and sharpen existing normal maps with Bilateral filtering
  • Generate roughness/specularity maps
  • Fine tune the intensity of emission maps
  • Realtime preview with settings for dominant, ambient, and point light sources
