Hi 
I have been playing a lot of farming simulator recently, and now i am curious on to how it’s done. Most of the mechanics are fairly simple, but how could the various states of the fields be painted properly?
The fields are seamless made onto the ground itself and can be expanded, so it’s something that have to be done directly onto a landscape.
The field itself supports various stages, with tyretracks that is alinged with how you do a given action. So if you plow a field in sorth/south direction, the plowing lines (Diffuse and normal map) are aligned this way. Same if you drive east/west or diagonal.
Then there are the various textures themselves. There are plowed ground, rolled ground, harvested ground etc. etc. that supports the above.
The texture chunks seem to be 50x50 cm or so, meaning that the entire world landscape are of these dimension.
I thought that it could be solved with some runtime landscape painting, with different materials that also support some kind of vertex painting for the tyre tracks.
Also this 50x50 cm detail size seems smaller than what unreal landscapes can do?
Is this how it is done, is it possible to do in unreal, or am i way off the mark here?
Thanks in advance
