You were right SzFeri82, mipmaps are the cause of that problem. However, it seems that I'm just missing something. For example, mipmap count of vanilla .2db file is 9. I save mine with the same count, but the problems still persists. I've lost couple of hours trying to get it right, but so far, it was all in vain. Any ideas?
Err... you've missed a topic, buddy. But nevermind, copy your RoadPatch.bnk here Euro\Bnk\Details and replace it with yours.
I won't do that cause someone might not like to have pine trees on a exotic location like Oahu. And besides, installation of 2D Nature last for only few secs. Older mods did have different FX.ini, but all my newer share the same file. That includes IP and 2D Nature series.
In other news, I've managed to find a way for a 3rd road type, I'll include it in v0.8.9. And I'll probably make complete overhaul of the roads once again. As soon as I find correct setting for mipmap, that is. XD
