American Truck Simulator versions

v1.5 [Dec 13, 2016]
- Added support for one-click setup of environment lighting loaded from sun profiles SII file (eg. /def/climate/default/nice.sii). This enables the best possible preview of a model in game like environment.
- Asynchronous paths initialization on startup, resulting in faster Blender startup and faster blend files opening
- User option to load all libraries and resources from sibling "base" directories also (by default off)
- Ability to reload library on the fly beside the setting where it is used (eg. Hookup Lib can be reloaded in Model Locator Settings)
- Improved material flavors behavior, with implementation of filter for non existing effects combinations (prevents user to create non existing effect)
- Added support for creation of SCS Locators and SCS Root via standard Blender add menu (menu accessible via Shift+A in 3D viewport)
- Normal maps properly visualized in 3D view even if active UV layer on object is not the one used for normal maps calculation.
- Reloading shader presets only when cache is out-dated (again speed-up of opening blend files)
- Updated Prefab Locators flags:
- added Map Point split lanes setups,
- added Weight Station CAT Spawn Point type,
- added Traffic Semaphores types: Traffic Light (virtual), Barrier - Automatic.
Improvements & Fixes:
- fixed unpropper UI snapping of TOBJ settings,
- ensuring same order of bone channels in PIA export (useful when working with VCS),
- negative add ambient material values supported in export and also visualized in Blender 3D viewport (more info here),
- properly reported python error on screen and in BT log while importing/exporting
- rejecting wrongly named SCS Root Object on export (more info here),
- reporting missing UV layer used for normal maps on export,
- reporting multiple animations with same name overwriting each other on export,
- properly handling none existing UV mappings aliases on import (most properly produced with ConverterPIX),
- fixed Blender crash if rapidly enabling/disabling SCS Blender Tools add-on,
- fixed error on import if no 3D viewport is found or active object is on currently hidden layer in scene.
