QUESTION Cant Open Blenderfile (Track) in KS Editor

[max schefer]

It Says that AC_Road_0 has no Material attached.
I am a complete beginner and tought i want to do a Map in 10 min but this is hard man hahahaha.
I created the "Track" like in this Video

I dont know if it is the right way for an Assetto corsa Track.

Yep, so you just have to assign a material to that mesh. BTW you won be able to drive on that mesh; name needs to start with a number other than 0 (e.g. 1Road or 01Road).
