Focus on simplicity and accessibility
The modding system is close to complete. This video showcases 3 models with varying performance that will be later used as examples for config setups.
So far, I was able to make everything work solely with glb exports from Blender and some configs. I'll make a detailed tutorial once everything is ready.
There is no scripting support for more complex mods. The current focus is on the simplicity and accessibility of only needing a program like Blender and not having to do any coding. This may change in the future as per modder needs, but scripting will likely remain a completely avoidable part of modding the game.
Steam Workshop and pre-release plans
I expect to have a new version working with Steam Workshop on the pre-release branch by mid August. If you see Steam Workshop content showing up for the game, keep in mind that you'll need to change the game version from the settings to access it.
Also, the pre-release version will be unstable, updates will sometimes lead to progress loss.
