      We are not working with the normal maps but we work directly with those "shading maps", and we create a normal map from it. But as far as I can see, the resulting normal map is pretty much the same we are getting. So at least we know this works pretty fine. Thanks.

      After fixing some nasty things with the light map generation, I tried your light maps with Sprite DLight.
      Merging them resulted in this normal map:

      And the other way round, the light maps generated from that normal map look like this:

      So, you are actually not working with normal maps, right?
      The light maps generated by Sprite DLight contain both light and shadows, so the term may be misleading and they should be called shading maps or something similar instead.
      The light maps you posted apparently only contain the light part, as the neutral color, which you would expect in areas like the center of the torso, is pretty much black.
      If this is really what you are after, you could simply adjust the histogram of Sprite DLight's light maps and set the input minimum brightness to something like 112 or 128, instead of 0, which darkens out the neutral areas and leaves you with only the lighter parts.
      Implementing this directly for Sprite DLight would be possible, but I don't think many users could make use of this, and having too many rarely used options just causes confusion, so I think the best solution would be a simple macro for the image editor you are using.

      I know how useful the control feature is. We are working directly with the lightmaps. But as I can see, the pictures obtained through the tool are different than ours. In our case the contrast is much more different.

      Is this result possible with the tool? Our art direction uses this kind of lightning, which boosts the lights and shadows contrast when the lights are closer to the game layer.

      Ahhh that is awesome! Thanks for the clarification :)

      Thank you :)

      The artistic control feature allows you to export the generated normal map as four light maps, containing the shading from the cardinal directions.
      This way, you can easily edit the shadows and highlights in any image editor, which is much more convenient than painting in the colors of the normal map or adjusting a depth map by hand.
      The four light maps can then be combined to a normal map again in the tool.
      The algorithm is pretty forgiving, so you don't have to paint everything too precisely to get a decent result.

      I'm not sure to understand how the artistic control element adds. Is it mostly adding a function to reimport edited normal maps in Dlight or is it some better ways to paint over normal maps ?

      Congratz on the goals!

      Congrats Dennis! I'm eagerly awaiting the release of your beta version tools!
