2025 Diamond C Multi-Vehicle Carrier Trailer

2025 Diamond C Multi-Vehicle Carrier
Version 1.1.0.0 — Complete Optimization & Rebuild Update

The 2025 Diamond C Multi-Vehicle Carrier has received a major optimization and cleanup pass for Farming Simulator 25.

This update was focused on making the trailer significantly more performance-friendly while preserving the original Diamond C appearance, functionality, animations, suspension, ramps, lights, and overall character of the trailer.

Instead of heavily reducing the visible trailer body, the optimization targeted unnecessary and extremely high-poly geometry throughout the model. The result is a trailer that looks essentially the same in-game while using only a fraction of the geometry of the original version.

What's New in Version 1.1.0.0
Completely optimized the trailer model from 1,428,829 triangles down to only 191,213 triangles
Removed approximately 1.23 million unnecessary triangles
Achieved an overall model reduction of approximately 86.6%
Rebuilt extremely high-poly mounting bolts and hardware using lightweight optimized geometry
Replaced all 10 high-poly front/chassis hardware bolts
Rebuilt the suspension shock-bolt hardware
Rebuilt the rear suspension hardware
Removed unnecessary modeled diamond-plate geometry and cleaned up the deck
Replaced the original extremely high-poly custom wheel setup with optimized GIANTS/base-game wheel assets
Retained the suspension/drum detail where appropriate
Rebuilt both rear ramp collision meshes from extremely dense collision geometry into lightweight, clean collision meshes
Preserved the original left and right animated rear ramps
Preserved trailer suspension components and visual details
Preserved Diamond C branding and overall trailer appearance
Cleaned obsolete wheel/rim configuration references after the new wheel conversion
Improved overall model efficiency without aggressively decimating the main trailer body
Verified the trailer in-game after optimization
GIANTS TestRunner 0.9.19: FULL PASS
14/14 TestRunner modules passed with 0 failures
Final estimated slot usage: 10
Optimization Results

The original trailer contained 1,428,829 triangles.

After rebuilding the unnecessary hardware, wheels, diamond plate, and collision geometry, the finished Version 1.1.0.0 model contains only:

191,213 triangles

That is a reduction of:

1,237,616 triangles — approximately 86.6%

The goal of this update was not simply to make the model smaller. The goal was to remove geometry that provided little or no visual benefit while keeping the areas of the trailer that actually matter looking detailed.

Trailer Information

Version 1.1.0.0 Summary

This is effectively a complete optimization overhaul of the original release.

Visually, it is still the same 2025 Diamond C Multi-Vehicle Carrier.

Underneath, however, the model has been extensively rebuilt and cleaned to provide a dramatically more efficient asset with better geometry management, simplified physics collisions, optimized hardware, and a much lighter wheel setup.

From 1.42 million triangles to 191 thousand while retaining the trailer's appearance and functionality — Version 1.1.0.0 is the version I wanted this trailer to be.

Enjoy!
