I'm working with the bevel and subdivision surface modifiers in Blender. I need to fix the topology now because I've removed these modifiers to start modeling the details. Thanks for the tips! I'll probably create an LOD2 in Blender as well for this mod.
From Blender you can upload a background and with a curve you can use "duplicate from curve plugin" for design your track. You can use also the GIS plugin:
You can import a path and a house... After that it is easy to reproduce a house with LFS objects for example.
Maybe just try to create only one car from scratch with blender and import on LFSEDITOR, try to create real physics, engine, animation,... That’s hard! I prefer create something in case of wait about something!
