So because I had to switch to my laptop for the time being as I'm abroad I decided to re enter TSC and I wanted to try out one of my favourite routes again: The Brennerbahn. But for some reason the grass tiles don't load properly. I also have Holzkirchen-Wörgl (also from RSSLO) installed and there it has no problems. Mind you I bought the Brennerbahn as a Steam DLC and Holzkirchen-Wörgl directly from RSSLO's website so dk how that affects this... I already reinstalled the Route and the problem persists
Do you have Train Simulator Academy installed? Don't know if Brenner route use it but it isn't uncommon for routes to that.
The above two very likely covers it, but generally look up the DLC on SteamDB and check the list of apps in the sub (package). Most usually that is enough. The Academy is occasionally required without realizing it (Horseshoe Curve does) indeed, and a select few routes use assets from each other.
Thank you guys. Turns out the Euro Loco&Asset pack was the answer. Stupidly it doesn't say that anywhere on the Steam DLC page... but SteamDB is the answer then
