= Introduction =
The following page contains modding guidelines for the new update of the game.
To better understand changes in units it is recommended to check [[Documentation/Engine/Units|Units documentation]] page.
= Recommendations =
* When basing your model on the original ones, add to your mod also <strong>ALL</strong> original /automat/ files used by it. The names of the files are generated as CityHash64 hash of theirs content so whenever we change the parameters of the material in any way, a different file will be used to store them and the original file might cease to exist if there is no other model utilizing the original parameters.
* When modifying original models, always include <strong>ALL</strong> components of the model (pmg+pmd) instead of just those you changed. Otherwise you risk crash if we change the model.
* As always when adding new objects to files which support multi-file approach (e.g. road_look.sii) it is <strong>HIGHLY RECOMMENDED</strong> to use suffix or prefix in the name to avoid conflicts with new objects we are adding in patches. Otherwise you might have to use the batch renaming functionality (see Batch renaming) to fix the conflicts when new patch appears.
= How to convert map =
* Load map
* Do rebuild (F8)
* Save map
= Changes & New Features =
== Light ==
TBA
Huge pile of new things: materials, shaders, map, vehicles, lamp logic, rendering, weather data .. :)
Our light is currently albedo-based system with some additional tricks.
Here is example of material ranges and their absolute limits http://download.eurotrucksimulator2.com/140_material_reference.zip (raw data) or http://download.eurotrucksimulator2.com/140_material_reference_converted.zip (converted, ready to mount as mod).
TBA
== Weather ==
Weather system was changed to more generic one. Elevation ranges of sun profiles might be any real value now (not just 5 degree grid), transition now can mix up to 4 textures on sky and can happen anytime - so no longer locked weather because of sky textures in specific times. Also, thanks to unlimited transition, there is no need for various climates and weathers to meet in any evelation point.
=== Climate profile ===
Climate profile can now specify usage of skyboxes of different climate ('''copy''') with few tweaks (arrays '''weights''', '''temperatures''' - define ). Copied climates are shown and can be edited in weather editor, but won't be saved.
Attribute '''copy''', defines name (token) of source climate.
=== Sun profile ===
Sun profile has few new attributes. Attribute '''stability''' defines chance of locking sky index for following sun profile (0.0 = completely random, 1.0 = sky index stays if possible).
Few color attributes have been changed from array of floats to float3 values. They all had '''_hdr_coef''' postfix in names. List of new names: '''ambient''', '''diffuse''', '''specular''', '''sky_color''', '''sun_color''', '''fog_color''', '''fog_color2'''. Also '''sunshaft_strength''' has been changed to '''sunshaft_color''' in same way. New attributes have same meaning as former ones.
Attributes '''min_scale''' and '''max_scale''' do not contain '''target_gray''' anymore, they are just multipliers. In addition new attribute '''scale_override''' defines allowed ratio for crossing of the limit (0 = no override, 1 = limit ignored).
Attribute '''eye_adaptation_speed''' was split to '''dark_adaptation_speed''' and '''bright_adaptation_speed''' for interpolated adaptation speed based on conditions.
Bloom has been remade. Before it was handled after tonemaping, with '''minimal_color''' mapped to 0 and '''half_intesity_color''' mapped to 0.5. Now its supressed below '''bloom_treshold''' and applied before tonemapping. Some older values are thus obsolete (radius, resizing_steps, minimal_color, half_intensity, multipliers, target_white).
The game can convert most of those attributes on its side after loading older '''sun_profile''' format for now but this support will be removed in future.
== Sound ==
There is new layer for map-based sound editation. It is accessed by "-edit -sound" commandline params which open map editor in sound editation mode, rest of the map items are inaccessible (sound items are inaccessible in regular editor mode).
There can be defined sound areas either for reverbs or ambinents and also put specific sound sources with some conditions.
For detailed description see https://modding.scssoft.com/wiki/Documentation/Engine/Sound/SoundWorld .
== Map ==
All filling stations totems are now dynamic signs with prices taken from pre-defined strings.
New editor features:
* Road edge overrides
* Lasso selection
* Snap mode for all collisions
* Tags in content browser
* Camera snap to ground options: Cabin view (2.5 m), regular height (8.5 m), extreme height (11.5 m)
* Allow using a comma for decimal points in text inputs
TBA
== Vehicles ==
Headlight behavior can now be defined in detail with many new options. Default descriptor is in ''/def/default_vehicle_lamp_setup.sii''.
In '''accessory_chassis_data''' it can be overridden per vehicle by '''lamp_setup''' definition. Content of '''vehicle_lamp_setup''' unit is experimental feature a will most probably change in future.
Engine brake can control retarder now. There is array '''auxiliary_brakes''' in '''accessory_engine_data''' units and works in similar way as same-named array in '''accessory_transmission_data'''. The only difference is ordering - engines auxiliary brake triplet is in order ''[engine_brake_strength, downshift, retarder_strength]''.
TBA
