I have released my latest logging map, Rancho Montaño.
But perhaps of more interest to the modding community, I have released a set of custom assets for MudRunner. These include their Blender and Gimp source files to support experimentation and modification. You can get them on GitHub: https://github.com/fred-rum/bbmmm-assets/
Custom assets include the extensive set of custom classes I created for Rancho Montaño. They also include a number of the experimental assets featured in the Big Book of MudRunner Map Making.
Enjoy!
