There’s a phrase we hear that often accompanies discussions on 3D strategy: Does it look real? People turn to 3D/AR/VR tools for high quality experiences presented in a more convenient, accessible digital format. So, it stands to reason that the more detailed, accurate, and correctly formatted the 3D model is, the better the quality of experience will result when it’s rendered. 

Our team of expert modelers is well-versed in the latest innovations and capable of creating accurate, detailed, adaptable, and optimized 3D models for every use. This includes incorporating high-quality materials that correctly interact with light within virtual worlds or settings — from reflections off marble countertops in a visualization of the kitchen of your dreams, to capturing the brushed chrome aesthetic of a fixture or even replicating the lighting conditions of the Parthenon in Ancient Greece. For 3D models with great looking textures, an understanding of how light behaves in the real world is non-negotiable. 

If you’re new to 3D rendering or looking for a deeper understanding of material systems, we’ve got you covered –– read on as we demystify the process. 

What is PBR? A refresher

Physically based rendering (PBR) is one way of making 3D models more realistic. The set of attributes has become the standard in modern 3D modeling software. It allows modelers to create photorealistic images through a shading method that simulates how light behaves and interacts with materials. 

PBR recreates real-world materials in a digital format by harnessing algorithms based on formulas. With new offerings that make color matching even easier, PBR means more realistic renders, more efficient workflows, and a cohesive environment. 

Unlike traditional rendering workflows, PBR maps real-world physical properties onto virtual properties. It’s physically based, relying on real-life properties determined with measurements and formulas. It also gives artists more control over how the materials of their models behave –– properties like roughness, metallic, self-illumination, and diffuse lighting are all possible with this method. 

VRay vs. Corona

To build realistic 3D models that will be used to replace photography, typically you’ll need to choose a material system like VRay and Corona that are designed for high resolution photorealism. Both are popular material systems that give users a host of PBR tools and workflows.

Corona can create high-quality, photorealistic results without any fine-tuning. This simplicity makes it straightforward, but that means sacrificing some flexibility. Still, it’s a beginner friendly option for users who want great results out-of-the-box. Because of its ease of use, speed, and realistic results, it’s a common choice for architects, designers, and 3D artists.

VRay comes with more possibilities but requires more advanced workflows. Users have more settings they can play around with to create any outcome they can imagine. The customization possibilities are endless, but using this rendering engine means you’ll need a higher skillset and familiarity with PBR principles like specular reflection, the Fresnel effect, and Albedo. VRay’s detailed render settings and per-object quality makes it better optimized for animations. It’s used in industries across the board –– from architecture to interior design, automotive, advertising, and games.

While there’s a lot of debate over whether Corona or VRay is a superior rendering engine, our verdict is: it depends! Every project has different needs, and while Corona’s offerings may be the best choice for one business, VRay might suit another business better. Materials systems play a big role in making 3D models that appear true-to-life, and understanding the different options available — and which one might be the best fit for your project — is important when considering your 3D budget.

At Loft3Di, we can help determine which option is best for your business and build exactly what you need. We work with all our clients in-depth to review the model or content requirements best-suited to build a scalable program. From VRay to Corona, our modeling team can work with different material systems depending on your needs.
