Good Day, I want to edit the weather probabilities in The Witcher 3. None of the existing weather mods advertise the ability to alter the weather probabilities. How do I go about making a simple mod that edits the weather probabilities? Nothing fancy with textures or the like. Just altering how often rain, snow, fog, etc. will happen. Are there tutorials out there that go over this? Thanks for your time!
