This highly detailed European arrow board trailer model represents a superb example of realistic 3D modeling, meticulously crafted to replicate the FLR (Flèche Lumineuse de Rabattement) Zéphir from the renowned Aximum brand. A common sight in France and other European countries, this model captures the essence of the real-world utility trailer, often used in traffic control and road works.

The model has been expertly created using Blender, a leading 3D software, showcasing an impressive level of detail and precision in its construction. The textures, which add depth and realism to the model, have been skillfully developed in Substance Painter, a professional tool known for its advanced material painting capabilities. For certain finishing touches, Adobe Photoshop has been employed, ensuring that every aspect of the model's appearance is fine-tuned to perfection.

One of the standout features of this model is its comprehensive range of texture maps. It includes a base color map, which defines the basic coloration of the model, a normal map for adding intricate surface details without additional geometry, a roughness map to control the material's glossiness and reflections, a metallic map that provides metallic sheen on appropriate surfaces, and a height map to give perceived depth to the textures.

The realism extends to the model's lighting setup, which is particularly advanced and lifelike. The trailer is equipped with fully functional turn signals, brake lights, and other necessary lighting features, all of which have been meticulously programmed to behave like their real-world counterparts. This attention to detail ensures an authentic experience for viewers or users of the model.

Moreover, the model includes a realistic license plate, adding to its authenticity. This feature is particularly noteworthy as it adheres to the specific styles and regulations of European license plates, making the model even more representative of its real-life inspiration.

For showcasing the model, high-quality renders have been produced using Substance Painter, highlighting the detailed texturing and lighting. Additionally, Blender screenshots with matcap (material capture) are provided, offering a clear view of the model's geometry and surface details without the influence of external lighting and reflections.

This 3D model stands as a testament to the capabilities of modern 3D software and the skill of the artist. It is an ideal choice for use in high-end visualization projects, simulation environments, or any application where a realistic representation of a European arrow board trailer is required.
