I have uploaded a zip file of missing icons for the Galaxy Forge, so that grey icons (DefaultPlanet) no longer appear with planets of which you don't have the icon (this mostly occurred with the dlc planets).
Simply extract the file into the ...\Galaxy Forge\Icons folder, then you have all icons together and creating galaxies will much clearer.

Ever since I've made something with the Galaxy Forge, I've been slightly annoyed by the many planets that are displayed as a gray mass instead of the way the planet actually looks. This problem has become bigger with the Forbidden Worlds and Stellar Phenomena DLC, so I looked at how the planets are being displayed and it turns out it's a very simple system.
In the ...\Galaxy Forge\Icons folder, you can see all the .gif images for the planets that are shown in the program, and a gray one for the default setting, which the program always reverts to when you put in something of which the .gif doesn't exist.
I made the necessary files and put them in the folder, with a very good result. So want to post the files online, but it appears that it's impossible to attach a file directly to this post.
I could obviously upload to a dropbox account, but I'd rather avoid doing that simply for a game's map editor. Does anyone have a suggestion?
