Introduction
Truck Simulator Big Rigs, one of the games offering the most realistic truck-driving experience, stands out with its wide roads, long hauls, and detailed vehicle variety. The game’s appeal comes not only from driving dynamics but also from the design of the trucks players use. For those looking to add new vehicles or improve existing models, vehicle modeling in Blender is essential. Blender, as a free and powerful 3D modeling software, is a preferred tool for both professional designers and hobbyist modders. This article will walk you step by step through the basic stages of truck modeling in Blender for Truck Simulator Big Rigs.
Preparation Phase
Proper preparation is crucial before starting truck modeling. This stage ensures the design process proceeds smoothly.
Reference Images
Collect photos of the truck from different angles: side, front, rear, and top. For long-haul trucks, proportions and details are especially important.
Blender Installation
Download and install the latest version of Blender. The interface may seem complex for beginners, but mastering the basic shortcuts helps you adapt quickly.
Workspace Setup
Add reference images to the scene using Image Reference. This will help you model the truck body with accurate proportions.
Body Modeling
The truck’s body is the most critical part of modeling. In games like Truck Simulator, vehicles’ large volumes must be correctly scaled.
Box Modeling Technique
Start with a simple cube. Use Extrude and Scale to roughly form the cabin, engine compartment, and chassis.
Using Loop Cut
Add edges with Loop Cut to define door lines, window frames, and cabin details.
Subdivision Surface
Some trucks have rounded edges. Use the Subdivision Surface modifier for these parts but avoid unnecessarily increasing the polygon count.
Detail Modeling: Cabin, Wheels, and Trailer
The details make trucks appealing to players. After modeling the body, move on to the finer elements.
Cabin Interior
Add essential interior details like the steering wheel, seat, and dashboard. Since the cabin is often visible in-game, this is important for realism.
Wheels
Use cylinder shapes to create tires. Apply normal maps for tread effects. Rims can be modeled with simple but strong lines.
Trailer
The trailer is an indispensable part of the truck. Start with a box shape and develop it with doors, side lines, and additional details. Modeling the trailer connection points as separate objects ensures functionality in-game.
UV Mapping and Texturing
Texturing is essential for achieving a realistic appearance.
UV Unwrap
Unwrap the model to place its surfaces on a 2D plane. This ensures textures fit correctly.
Texture Preparation
Use software like Photoshop, GIMP, or Substance Painter to prepare metallic paint, transparent glass, and matte tire textures.
Normal and Roughness Maps
Simulate scratches on metal surfaces, gloss effects on the cabin paint, or rough tire surfaces using normal and roughness maps.
Exporting to Game Engine
Once the truck model is complete, optimize it for in-game use.
Format Selection
Export the model as FBX or OBJ, widely supported in modding communities.
Polygon Count
Keep the model under 50,000 polygons for mobile performance. Extra details can be added via textures.
Pivot Points
Correctly position pivot points for wheels and trailers. Misplaced pivots can cause rotation or connection issues in-game.
Tips and Recommendations
- Start Simple: Begin with a basic truck body before attempting complex rigs.
- Use Shortcuts: Blender shortcuts like Extrude (E), Loop Cut (Ctrl+R), and Mirror (M) streamline workflow.
- Leverage Communities: BlenderNation, Reddit, and Truck Simulator modding forums provide numerous examples and guidance.
- Optimize: Maintain a balance of low polygon count and high-quality textures for mobile performance.

Conclusion
Blender is a powerful tool for vehicle modeling in Truck Simulator Big Rigs. Starting with the body and progressing to cabin, wheels, and trailer modeling, followed by UV mapping, texturing, and game engine export, completes the workflow. With regular practice, you can create cleaner, optimized, and more realistic truck models. This process enhances your modding skills while personalizing your in-game experience. Driving your custom Big Rigs vehicles on long hauls is both educational and enjoyable.
