TONAR 9540-0000011 version 1.0.0.1 for Farming Simulator 2019 (v1.6.0.0)

A real existing super-heavy grain semi-trailer with a 72-ton capacity "TONAR 9540-0000011". It allows transporting both grains and root crops. Requires an especially powerful tractor. Based on the work of authors: Weder.Deruz and kamazgt. The model has been brought up to the quality of the original. No log errors, no significant problems.

Change log version 1.0.0.1:

Custom rear lights replaced with lore lights from the shared folder. As a result:

- The issue where the visual lamp of the turn indicator stayed lit instead of blinking after activation (until it was turned off) has been fixed;
- The problem of missing bolt heads on the plastic cover textures of the lights has been fixed;
- The problem of rectangular outlines of the corona light flare effects on custom lights under bright sunlight has been fixed;
- The last critical log error that appeared only when the turn indicator was activated has been fixed: Error: 'turnLightRight' (turnLightRightShape) doesn't have all required vertex attributes for material 'corona_orange_mat';

Other changes:

- Both types of log errors (warning, error) are completely absent under any conditions;
- Missing light sources (turn indicators) have been added. Now there is illumination on the asphalt;
- Coordinates of existing light sources have been mathematically symmetrized;
- Light sources on the front trailer’s license plate frame have been removed, as there are no number plate illumination lamps there;
- Custom tires replaced with lore tires, since the former lacked deformation models under load and were obviously imported as-is from FS17;
- Added two road tire options and one offroad tire option to choose from;

Tire deformation configured depending on the mass of the transported cargo. As a result:

- The mismatch error between the visible wheel diameter and the game’s perceived diameter has been fixed (the wheel no longer sinks into the ground);
- X coordinates of wheel mounting points have been adjusted symmetrically;
- Trailer suspension reconfigured (Y coordinates of wheels, spring stiffness, shock absorbers, tire deformation depending on weight, speed, surface, etc.);
- 3D model of wheel rims rewritten, real holes added, texture seam removed;
- 3D model gap in brake drums removed;
- Chrome added to the rods of the main hydraulic cylinders;

Spare wheel rewritten and is now a separate object, not part of the trailer’s 3D model. This enabled the following:

- When selecting a different tire option for the main wheels, the spare tire changes accordingly (except for especially wide offroad tires). These require additional 3D adjustments, which were decided against to avoid over-perfection;
- Unrealistic mirroring (including tire inscriptions) of the right spare wheel removed;
- Nuts on suspended spare wheels removed, real holes added.

Other changes:

- Lateral resistance of front and rear wheel pairs radically reduced, lateral friction of the central wheel pair increased threefold, which greatly improved trailer handling at large steering angles and reduced unrealistic tractor tilting;
- Fixed the issue where front trailer parking supports sank into the ground; collision of front trailer parking supports replaced with those from the rear;
- Fixed a critical error where the 3D render of the front trailer did not display in the store showroom until at least one instance of this trailer was present on the game map (manifested after purchase, caused by collision of front trailer parking supports);
- Parking support height adjusted more accurately;
- Root crop unloading animation perfected;
- Drop-side animation rewritten; now grains and root crops do not spill through the texture, and drop-side angles align vertically at maximum bed tilt;
- License plate signs replaced with marketing versions; Ukrainian plates were inappropriate;
- Custom sounds removed and replaced with lore sounds from the shared folder for resource optimization; custom sounds were neither high quality nor practically meaningful;
- Store icons redone towards lore style (aspect ratio, scale, color, shadow, alpha channel);
- Mod icon redone towards lore style, lore background added;
- Author settings that caused trailer micro-icons in-game to overlap removed for convenience and to align with lore interface state;
- Trailer model names clarified;
- Mod text information corrected;
- Other languages removed, only Russian remains, because Russian is embedded in the code and translating to other languages requires a separate effort with text variables input;
- Mod code completely rewritten in lore style; grammatical errors removed from object names; object locations labeled according to ZX template (e.g., Rear Left or Middle Right);
- *.png files in text code replaced with *.dds, reflecting reality;
- Air consumption by brakes added;
- Attachment point coordinates reconfigured;
- Missing collisions added;
- Fixed the issue where cargo was visible in the corners of the depressions of the front trailer;
- Front trailer fifth wheel height adjusted. The visual fifth wheel replaced with a lower one. According to drawings, cargo compartments of front and rear trailers are not level but offset in height. Now everything matches;
- Outdated FS17 shaders replaced with current FS19 shaders. The trailer now shines in the light as a painted object should;
- Wear textures added.

Issues:

- Suspension part animations still do not work. Preparation has been done;
- The first axle is liftable in the original (so-called “lazy axle”), but this is not implemented in this model due to lack of game mechanics support for automatic axle lowering under load or wheel failure due to overload. Transporting 72 tons on two axles would look questionable;
- Coupling with other trailers may cause unpredictable consequences, which is not due to errors in this specific model but due to the size dimensions of other trailers and the game’s physics engine features. This also often occurs in lore.
