Once the project is approved, the normal baking process begins. When using a low-poly model, smooth chamfers are not provided, but they can be imitated using shaders. This method allows you to create visually appealing details, giving the model a more complex and realistic look without increasing the polygon count. Correct use of shaders helps improve graphics quality and performance in games and other applications.

Pedro creates realistic wings by applying segments to a height map in real time. He uses two brushes to achieve different effects, resulting in a detailed and believable image. This approach ensures a high degree of realism in the modeling process, which is especially important for animation and visualization.

The process of creating textures in Blender is similar to using Substance Painter, but has its own unique features. The key point is the need to use a 32-bit black and white height map. Pedro spent about half a day rendering the entire surface. Proper use of height mapping in Blender allows you to achieve high-quality visuals and realistic details in your models.

Pedro combines the height map and the previously baked normal map using the Bump Map node, creating a single normal map. This process improves the details and textures of the model, providing a more realistic display of the surface.

The normal map looks great, but to increase realism, you can add distortions using node combinations. This will create a more detailed and believable image, which is especially important in 3D modeling and visualization. Using additional effects and textures will help enhance the perception of depth and volume, making the final result more impressive.

Linear light Linear Light can be found in the Mix Color node tab. This blending mode allows you to effectively combine colors and lighting in your projects. Using linear light ensures a smooth and natural interaction between layers, improving the visual perception of the final result.

While the changes in a mobile game may seem minor, they significantly increase the level of realism of the model. Moreover, the updated model will be actively used in marketing materials, which will attract more attention to the game.

Pedro spends approximately 1.5 days creating a high-poly fighter jet model, while larger aircraft take approximately 2.5 days. The quality and detail of the models directly depend on the time spent on their development, which allows for a high level of realism and accuracy in the depiction of aircraft.

Pedro emphasizes that his method significantly reduces modeling time compared to traditional approaches. For example, the development of a heavy-lift aircraft took only 10 days, while his colleague spent four weeks on the process. The use of innovative technologies and optimization of workflows make modeling more efficient and faster, which significantly increases competitiveness in the aviation industry.

Method Pedro provides the ability to efficiently model complex objects in a hard surface style without the need to first create a high-poly model. This approach streamlines the development process, allowing you to focus on detailing and texturing, significantly speeding up the workflow and improving the quality of the final product.

After baking the normals, it's important to create additional textures such as albedo, ambient occlusion, and roughness. In Blender, you can use the Kit Ops add-on, which provides ready-made shaders. This tool significantly simplifies the creation of high-quality textures and improves the visual quality of 3D models. Proper use of albedo, ambient occlusion, and roughness allows for a more realistic display of materials and increases the overall level of detail in the project.

Pedro discovered that by combining nodes, it is possible to combine different materials on a single surface. This allows you to add an alpha layer as a texture, making the process of painting details in real time more efficient and flexible. Using these nodes significantly improves rendering quality and opens up new possibilities for creating complex materials and effects.

In this video, Pedro demonstrates how to work with two materials from the Kit Ops library: unpolished metal and blue auto enamel. He uses alpha brushes to achieve a distressed effect, giving the models a realistic look. This video will be a useful resource for anyone looking to improve their texture and material creation skills in 3D design.

Fighters have machine guns built into their wings, and it is important to detail the places where the bullets exit to create the effect of burnt paint. This adds realism to the model and makes it more impressive. Correct detailing of such elements helps convey the atmosphere of air battles and enhances visual perception. Using textures and paint application techniques in these areas allows for maximum verisimilitude, which is especially important for collectors and modelers.

Pedro's model is unique thanks to the addition of textures with identifying marks and inscriptions. Users can easily change the primary colors in the shader settings, allowing them to tailor the model to individual preferences and project requirements.

The result is a complete set of textures ready for integration into the game engine. These textures are optimized for use in a variety of projects and provide high-quality graphics. Import them into your game engine and create unique visual effects for your games.

Pedro's fighters are featured in promotional materials for Wings of Heroes. Archival wartime photographs are used to create static renders, lending historical authenticity and visual appeal to the materials. These images effectively showcase the fighters' unique design and characteristics, helping players better understand their role in gameplay.

To achieve high levels of realism in his work, Pedro uses photo textures of the sky, available on various marketplaces. These textures are typically inexpensive, making them accessible to most users.
