I'm in the process of making several of our scenery locations seasonal. Here's some images from Navman's Retreat. These will be available soon and you'll need to have the season switcher utility by Rod Jackson installed and working before you'll be able to use these new seasonal files.
To get that if you haven't already, download and install Khutze River Lodge or Canoona Fish Camp. Those two files come with the seasonal switcher Rod made for us and instructions are inside those readme files for installation and usage of the seasonal files and switcher. It's very easy.
