Vehicle Shader Guide

Overview

The Vehicle Shader in Farming Simulator is utilized for rendering various components of vehicles with advanced visual effects. This shader allows for the implementation of dynamic textures that can represent dirt, wear, and environmental interactions.

Understanding the Parameters

The vehicleShader.xml file hosts a range of parameters that control different aspects of the vehicle's appearance:

RDT

Manages details related to reflective textures such as scratches, dirt, and snow.

dirtColor

Specifies the overlay color for dirt effects on the vehicle.

offsetUV

Pertains to the manipulation of UV coordinates for texture animations on the model's surface.

colorMat

An array parameter that facilitates color customization through masking, enabling multiple color variations on a single model.

Applying the Vehicle Shader

To apply the Vehicle Shader to your vehicle models:

1. Assign the Shader: In the Giants Editor, link the vehicleShader.xml to your chosen material.
2. Adjust Parameters: Modify parameters like RDT to get the desired level of detail for effects such as dirt or scratches.
3. Texture Setup: Ensure that your texture maps, such as diffuse, normal, or specular maps, are correctly assigned to the shader.

Shader Variations

The Vehicle Shader includes multiple variations for different effects. Here are some, with more details on their dedicated pages:

• Motion Path Rubber Variation
• Mesh Scroll Variation
• UV Scroll Variation

... (continue with other variations) ...

Tips for Modders

• Start by creating a copy of the shader file before any modification.
• Test changes incrementally to observe their effects both in the Giants Editor and in-game.

Troubleshooting

If you encounter issues:

• Shader Not Rendering: Verify the accuracy of texture paths and parameter ranges.
• Unexpected Visual Effects: Review the specific requirements for the chosen shader variation such as vertex colors or UV map arrangements.

With this guide and the detailed sub-pages for each variation, modders at all levels can effectively use the Vehicle Shader to improve their mods.
