Incari’s PBR extensions and glTF integration

When I started working in the 3D industry around 8 years ago, there were two widely used 3D model transferring routes, OBJ and FBX. This left two options – rebuilding assets if transferred between software or biting the bullet and leaving all designers to learn the same software. Today, there are more options and ways to seamlessly transfer and create high-quality graphics.

glTF, the Jpeg for 3D

A new file format is paving the way for software application file transfers. glTF, Graphics Language Transmission Format, is an open, royalty-free 3D Data Format with top-level elements like animation data, textures, materials, and object hierarchy, to name a few.

Easy to incorporate external 3D designs without retouching and modifying and memory efficient. This makes it a great candidate for web and cases of limited resources. glTF 2.0 now also supports modern physically-based rendering materials, compatible with all rendering APIs. The list of software supporting glTF is growing with some services even built around it, like Sketchfab.

The 3D artist’s bread and butter

PBR uses a physical understanding of light transport to define lighting rules for 3D-based images in the shading and rendering process. Visualizing material properties like roughness and metalness to create highly realistic 3D models.

The extension of PBR materials in Incari Studio offers even more customization. You can use texture for more granular control over spots of roughness. Think of black as 0% and white as 100%.

With the help of multiple textures, like color, roughness, and ambient occlusion, you create a PBR material. All textures are automatically mapped correctly in Incari with a dedicate PBR Shader. Creating higher visual fidelity and reducing manual work. Here is an example of an interactive render made with Incari Studio.
