I hop in and out of Linux a lot, and Terragen is the one Windows program I actually use semi-regularly that I can't really replace (even if I wanted to). Currently it works fine in Wine/Bottles on my main PC, though slower and the UI looks kinda janky, but it has issues working on laptops since custom DPI scaling breaks it. I know there's a render node, though I've not tried it, and I gather a Mac version dropped. Is a full Linux version even on the roadmap?
