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.

Patch v1.1 released

Patch it out! Since I've elaborated content of this patch in blog posts I will keep this short and just link them:

Main features:
Complete rework of medium and large elements, greatly increasing their quality and flexibility:

Optimization resulting in massive fps gain when processing large textures:

There are also some quality of life improvements as slider value normalization and left menu scrollbar mouse wheel response.

I am going to monitor feedback for a week after which I will start Patreon poll for next set of features. Big thanks to all Patreon supporters. If you like this software and would like to support its further development please consider supporting on Patreon

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
