So, tracks are on hold from me for the moment. I will revisit corrections to old tracks, but not new ones, as there are supposed to be a lot of changes being made to how these are calculated? At least, that is the rumor mill’s take on things. Existing tracks are going to have to be redone/reworked for the new UE4 full release apparently, so no sense making new tracks to add to the work later.
EDIT: To those who are interested in making their own tracks, I did a tutorial here (which was made using the first version of a track editor we received based on a browser from @ElSaico and…no longer exists?), which mostly also applies here (which is the current stand-alone track editor created by @BitTwiddler.
Additionally, for basic information about the LUA file and image you’ll be working with, @Der_Bayer originally introduced the concept and art of track building with a solid explanation of how it currently works here.
