I've been wanting to do some 'space' scenes for a while but tools to create star fields, planets, nebulae, etc. either don't exist or (if they do) are commercial plugins. So I decided to write my own. I've got several in the works but the first is now available - a shader for creating background star fields called 'StarScape'. Rather than post multiple sample renders here, you can see a few on my site at https://microbion.co.uk/html/starscape.htm
I'm no artist, so I'm certain many people will be able to do a lot better than that 😀.
It's completely free, has a full manual and is available for C4D 2024 (Windows and macOS) and 2025 (Windows only). I'll upload the 2024 version to the Downloads section here or you can get it from my site at the above link.
