@Pangaea666: I used some mods which don't depend on Redkit. Redkit mods however are impossible to use with the Linux version. CDPR did a poor job there, or rather they didn't pay VirtualProgramming to do that job.
Regarding Wine, I never tried using REDkit from it. If you are saying mods don't work in Wine with REDkit - I suppose it's an issue.
Do you know exactly why it's impossible (?) to get some mods to work on a Linux system? For instance, I've no idea where the base_scripts.dzip file has gone on Linux. Have Virtual Programming included this into one of their files? That would make it very hard to get mods to work on Linux
From what I can tell, XML file changes work fine on Linux, but not script changes. It's peculiar that all the dzips are there -- except base_scripts.dzip.
I haven't tried to run the game via Wine, only RedKit (because there isn't a Linux version of it). RedKit itself appears to work fine via wine (or PlayOnLinux in my case), so my comment was just about that really -- that it's kind of ironic that the tool that can be used to make mods with works on Linux, but not the mods themselves. Then again, for all I know the game itself runs better through wine than the wrapped "Linux" version. Haven't tried it.
This mod business is quite frustrating though, and it would be grand if there was some way to get more mods working on Linux. For a company that embraces DRM Free-ness, it's very disappointing there is so poor Linux support, and modding support for that matter. Still no sign of Witcher 3 for Linux, which means I'm unlikely to buy it, given that I've finally tossed off the Microsoft chains, and this time for good.
