Correct, just the Light at this moment, and just the Light model that came with the DLC. Since it is a nice feature, perhaps we can consider moving it over to the other classes. We'll definitely release a template with UV layer to 'guide' you; along with the Hinds templatePerhaps DnA can confirm? Also what would be great is a photoshop template for the stickers layer - it's quite hard to line them up at the moment!!
The NC times especially are very, very tough. Most trials will have some special tricks you need to discover and which will usually shave off tens of seconds. For the first one the loop around the scraper is one example; look at the trailer for a clue. Also: the direct path will not always be the fastest in the end. Safety instructors will not like me for this one, but keep pushing for yellow and near-red warnings.
I believe we still intend to roll out this DLC on Steam automatically, but there's no technical reason why you cannot install it using the released installer
