Hi guys, I want to make a circuit race for nfssa, and I have a 2 questions I couldn't find an answer to in other threads:
One of the things I wondered was if tracks need to be fully closed by invisible walls and arrow barriers or not, because I have a particular part of the circuit, where two parts of the track are right next to eachother and can't think of an elegant solution to stop people from just jumping from one road to another and gaining a big advantage. I don't want to put a fully opaque wall there and most of the other flat objects are only transparent on one side. Here's a picture of what that part of the track looks like:
The other thing is putting arrow walls on roads, that are either decending or acending. I thought of just using a 2x high flat arrow wall or maybe using a barrier with an invisible wall behind it, but I just wanted to know what techniques people with experience use.
