Another superfun track bring to us by you, thanks!
For me, no need to implement 3D vegetation (at least in the present day) with the counterparties that must be assumed regarding the drop in performance; I consider that the treatment that this mod has with the vegetation, while not perfect, is quite effective and has very good results despite how basic the trees, shrubs and plants used may be... I like it a lot, it's original, a bit different from what we can see on most tracks.
And now, what would improve: apart that I would like that the transition between dirt and asphalt were a little more elaborate, the only detail that I miss is that several elements (such as some fences, piles of tires, and the checkered "totems" of the curves) were objects with collision... if that were possible, of course.
Thanks again.
An update is being worked at the moment, and I will evaluate the items you noted and any changes if any.
cheers
