What is it?

Why cars are doing this on my map (in all time on the same place).

And how to make alpha texture on object?

have you dropped a 'car park' on the top or bottom of that part of the map? if so look its arrow and you'll see why!

I looked at object list, but there aren't any carpark.

is the car just going round and round in circles?

No, is still staying on the same place.

And is there anyone who could tell me how I could make alpha-texture and glass-effect and still-lighting texture for e.g. traffic light?
