THIS IS NOT SE ADDON
This is just cylindrical bump maps for planets. If anyone can update them into SE addon and post link there I would 100% appreciate that.

(do not download Charon, It's horrible)

Kexitt, you mean by making a cubemap?

Yes

Unfortunately I'm having troubles with the necessary raw conversion from jpeg files, I tried a couple of programs without success.
I did a conversion for Callisto, but it seems the original file has some horizontal glitches, probably due to jpeg compression algorithm.

Kexitt, I'd be happy to process these maps for SE, but they need to be of the best possible quality to look good in the program. Can you upload lossless versions? (PNG, TGA, PSD, TIF, etc.)

Why do you talk about this in my topic? This is about my maps.
BTW I may upload some of my maps in 16bit png later

There's a Photoshop plugin called Flexify which, among its huge number of options, can convert from a cylindrical equirectangular projection to a horizontal cross. It has a 30 day free trial and costs US$54 afterward. I own the plugin and I can help convert your maps to cubemap format if the SE converter doesn't work, but it may take some time, especially when it comes to matching the directory structure SE requires for a plugin.

Julian did you try the Flexity? I really want to know if it can do same job as CubeMap cause this soft is something that people can't work with.

On 14 of feb I will upload many high quality maps for planets. You will not miss it. I hope I will not lose that acc. Those ones will be 4k 16bit pngs so they will be convertable.

Maps for Pluto and Charons and also fictional maps for Eris, Makemake and Sedna:

Enjoy!

Kexitt1, Pluto bump is damaged. One user already told that on Deviant and I confirm that too.

Reuploaded. Try it again

Yeah, now it's fine.
About Pluto map - you worked well on it but you forgot 1 important thing, the size must be 8192 width, twice the size of yours. CubeMap can work with any size textures but only this large ones give a good result.
Also your map is very brave and a bit fairy-tale. I mean nobody knows the southern side of Pluto and it would be wise not to think out that much. In many years humanity will get the full truthful map and will see that you mistaken with that non-existent canyons. My advice is to work a little bit more and make the southern hemisphere modest and minimalistic, so that it corresponded to northern one. Look on the north once again - there is nothing that interesting, so why the south must be that impressive?

to convert 8 bit simple cylindrical maps to a cube
or cube to simple cylindrical i use the FREE OpenSource perl tools for Hugin
"pano tools "

install hugin
and from CPAN install it from the terminal http://search.cpan.org/dist/Panotools-Script/
