Kerkythea Rendering Software

To use Bump map in Kerkythea requires a simple tweak: Invert the values of bitmap image.

The bump image was provided by olve11 in his post:

Bellow we can see in the top row how that image affects the sphere on preview. We can note the mortar seems to be coming out of the wall. In the bottom row we see that by checking the Inverted property in Bitmap Option fix the problem:


But, if we want to use Normal maps then we have more work to do.
Differently of bump map image if we invert the bitmap values we are going to get an ugly effect.
So - if we are creating the textures - the best approach can be invert the bump map image first and use it to generate the normal map. I use GIMP for that most the time.

Here are the maps I created from that one provided by olve11:

For the normal map works fine in Kerkythea, in GIMP, when we are in the NormalMap dialog we must to check the Invert option as bellow:


Bellow we have a comparison of all these bump/normal maps. The comments are in the image:


I hope that can be useful. If someone else wants to play with it here is the files for download.
