I am creating a new map for Farming Simulator 22 based on Stryn in Norway.
This map is made mostly by using Houdini. Not much have been done manually in Giants Editor except fine tune some locations to the buildings placed there.
I am also using custom scripts to send data between Giants Editor and Houdini to rapidly create new roads, road barriers, adjust the terrain etc.
I am reusing as many buildings as possible from the Rennebu project. The buildings kit is likely players have installed already if they played on the Rennebu map, and other map makers have started to incorporate the buildings in their maps.
