BeRKA is back

I am back from my trip to planet Carinthia. Now I have a lot of work to do. There are some new Traveller products I should post links to (at the Zhodani Base Facebook Page), and I must decide which of the very good 16 entries in the 76 Patrons contest that are the best ones. I also have a lot of pictures to post at the berka.se blog.

Planet Carinthia
Planet Carinthia

I made this image using GIMP and the gas giant plugin. I changed the colors of the my image from Carinthia and then added the gas giant as another layer. Then I changed the opacity of the added layer to make it look good.

Another big hex

I thought I should try a variation on the big hex style. This time for an important star system in the Spinward Marches.

All planets (except Cipango) was made with GIMP plug-ins. The Cipango ring system was made with the planet rings GIMP plug-in. The planet Cipango was made from an old texture that I have used for other maps of Cipango.


The distances for the planets from their “sun” Cipango-Taiyoo is calculated using a modified Titius-Bode law. Using the formula below for the Cipango system:

a = 0.7 + 0.2 · 2 m

For our solar system the formula is:

a = 0.4 + 0.3 · 2 m

Where a is the distance in AU, and m is the orbit number. (Where m is 1 for Earth.) The modification of the Titius-Bode law was needed to fit two planet orbits into the habitable zone. This gives the Cipango system a total of 3 garden worlds.

Free Gimp Plugins

With the help of some free Gimp plugins (Planet Render and Star Scape) I have made the image below. While it might not be as good as the plugins from Flaming Pear, it is still cool that You can make some nice images using free software. 😎

If I would have tried a bit harder, I might have been able to do something that would have looked a bit better. The image below is just to show You what is possible. (The image has also been compressed to a jpeg image so that it will load faster. This compression have added some distortion as well…)
