Shader Color Fix

This mod restores the color customization functionality for vehicles that rely on the LS22Support shader in the new engine. Shader parameters such as Colormat0, Colormat1, etc. are no longer supported by default – this mod brings them back. An updated vehicleShader.xml with bug fixes is included and can be copied into your own mod archives. The XML schema for color configuration and design configuration follows the familiar structure from previous versions, allowing modders to continue offering flexible vehicle painting options for their custom vehicles.
