AdvTrains Livery Tools fulfills the brief for just about every discussion put forward so far about livery features for AdvTrains, and does so in such an intuitively designed, user-friendly way. Marnack has achieved here what many have discussed but not actually gone and done.
Before Livery Tools, the best we had was doxygen_spammer's Multi-component liveries (part of doxy's Minitram). That involved the use of the external dependency on Bike Mod, and an arduous process of memorising and recalling a few "special" numbers on the Bike Painter to apply special painting functions. No more! With Livery Tools, it's all laid out in an intuitive formspec with so many presets to help you along and an instant preview.
Livery Tools is survival-friendly, with a crafting recipe provided for Minetest Game (the only really support game for AdvTrains) to craft its core item, the Livery Designer Tool. The Designer Tool has four tabs:
The Current Livery tab is a simple preview/descriptive formspec
The editor tab is the main tab you will be using. One simply selects a template, basically a set of shaped layers, and then what paint to apply to all of those layers. There are preset colour names plus a great colour selector dialogue. here you can also get template information or save the livery to apply it again to another wagon.
The Saved Livery tab lets you quickly apply the same livery you just made to more wagons.
Predefined Liveries is great to apply liveries that the mod author or others have made, which is great for inspiration. One of the really great features stands out here, which is the ability to apply liveries from 3rd-party packs to your wagons.
Livery Tools brings us the ability for in-depth customisation for those who want it, plus the ability to make templates to inspire. It's a creative breakthrough, and I can' t recommend it enough.
