Terrain modding! v5.21

Today's update finally replaces the old and terrible "QuickTerrain" modding system with a proper modern system with heaps of new features!

This has been on my to-do list for around 5 years, since QuickTerrain was always suppose to be a temporary feature. This new system uses the modding manager (just like train mods and prop mods) and makes the whole process infinitely easier and actually useful!

You can find a full step-by-step guide on how to make a terrain mod for a map from scratch here:

To summaries though, this terrain modding feature lets you import 3D models from external software (like Blender) to use as terrain, and you can export the track & props in your map into raw 3D models to use as a guide to create your terrain.
This means you can easily line up the track in your map with the terrain mesh!

This 3D modelling method is exactly how I make most of the official maps, and it's how I create the neat "clipped wall" effect on maps, where the scenery is aligned with the table edge of the layout. This is commonly seen in real model railways:

[h2]Full features of the terrain modding system:[/h2]

Import 3D models and textures in-game using the modding manager menu (just like train mods and prop mods).
Export in-game maps (both props and track) as raw 3D models. You can export the entire map or choose smaller sections using bounds boxes.
Set the view distance and low-detail view distance, and swap out to low-detail versions of the terrain when viewed from far away.
Set different parts of the terrain model to only be visible in large scale, or miniature only, and on different skybox regions.
Set a custom collision mesh.
Package terrain inside a save file when uploading to the Steam Workshop (just like other mods).

The map exporting feature is especially interesting, since it basically means you can take anything made inside Rolling Line and turn it into a raw 3D model!

There's also now a "Terrain Mod" category tag on the Steam Workshop:

[h2]This update also includes a few minor fixes[/h2]

Fixed shading on the popup message box
Fixed text alignment on the Brazil tanker freight wagon
Improved the collision on various road marking props
Disabled temporary Halloween menus (it's back to normal now)

And that's everything for now!
If you want to have a go at using the new terrain modding system, please read the full detailed guide, since there's a ton more information than I can squeeze into this news post:
