Enhancing Photorealism in 3D Scenes Using PBR Textures

Creating a photorealistic scene in 3D graphics often hinges on utilizing high-quality Physically Based Rendering (PBR) textures. While this is a common tip, does it necessarily have to be the standard practice? In this blog post, we explore how working with textures captured under different lighting conditions can lead to more realistic results, even when textures seemingly do not match well. We will delve into a brief tutorial where we illustrate this concept by creating a compelling video using only two photos: one taken with a mobile phone and another sourced from unsplash.com.

Getting Started: Crafting the Scene

To kick off our project, let's begin by setting the stage. Starting with a cube that aligns with the dimensions of a small store, we rely on our visual judgment to approximate the size accurately. Adjusting the camera angle to mimic that of the photo is crucial for unwrapping the texture effectively. This step sets the foundation for achieving a seamless integration of textures within our scene.

Refining Details with Loop Cuts

Introducing more geometry through loop cuts plays a pivotal role in refining the texture mapping. By strategically adding loop cuts and extruding sections, we gradually enhance the details of our model. This meticulous process, starting from prominent features to subtle nuances, is instrumental in elevating the overall realism of the scene.

Texture Application: Blending Realism

As we progress, we focus on applying textures to bring our scene to life. Leveraging the base color from the store image and incorporating the concrete texture for bump and roughness qualities, we ensure a coherent visual appearance. With the careful utilization of two UV maps, we can seamlessly combine elements from both textures without compromising the integrity of the design.

Illuminating the Interior

Moving to the interior components, we integrate additional details sourced from unsplash.com. By utilizing an emission shader based on the brightness values of the photo, we illuminate key areas within the scene. Fine-tuning the lighting with color ramps and matte nodes enables us to exert precise control over the visual aesthetics.

Enhancing Realism: Adding Depth and Texture

To enhance the visual appeal further, we incorporate elements such as glossy concrete textures and dynamic shadows. By adjusting the roughness input and leveraging light angles judiciously, we accentuate specific features and introduce subtle details. The interplay of light and texture allows for the creation of nuanced effects, such as integrating transparent elements seamlessly.

Final Touches and Conclusion

As we approach the finishing stages of our project, attention to detail remains paramount. Incorporating color grading, effects, and meticulous adjustments, we refine the scene to its full potential. The culmination of these efforts results in a visually stunning animation that captivates the viewer.

In conclusion, the process of enhancing photorealism in 3D scenes extends beyond using high-quality PBR textures. Through thoughtful texture blending, meticulous detail refinement, and strategic lighting applications, artists can elevate the realism of their creations significantly. Experimenting with textures captured under different lighting conditions opens up possibilities for creating uniquely immersive visuals.
