Overview

3Delight for Maya can render any Maya HypershadeMaya HyperShade network. Scenes that are setup using the usual Maya workflow will work out-of-the-box with 3Delight for Maya. On top of that, 3Delight for Maya provides additional utility nodes and additional materials for physically plausible shading.

Materials and Shaders Library

...

In addition to standard Maya nodes and materials, 3Delight for Maya comes with easy to use and physically plausible materials. 

3Delight Material – A hightly versatile shader dual-layer material to simulate a large variety of surfaces.
3Delight Skin – For rendering (human) skin.
3Delight Glass – For rendering glass.
3Delight Hair – For rendering realistic hair.
3Delight Metal – For rendering physically correct metallic materials. 
3Delight Sky – For rendering physically correct sky dome.
3Delight Primitive Attribute – A utility to read & output primitive attributes into a shading network. 

In addition to these materials, we provide a utility node that allows you to inject RenderMan Shading Language (RSL) code into HyperShade network. We call that utility node The RenderMan Code Node and a tutorial for creating such node is available in Creating Custom HyperShade Nodes.

Info

3Delight for Maya support Maya's HyperShade network; it automatically converts (at the start of the rendering process) HyperShade networks into RenderMan shaders that are used by 3Delight to render the image.

About Physical Plausibility

...

"Physically plausible" terminology has been introduced in the computer graphics literature to described a certain category of BRDFs [1]. In technical terms, a physically plausible BRDF:

...

The expression "physically plausible material" is used in the VFX industry, somewhat loosely, to indicate that the material is based on such BRDFs. In reality, it is very difficult to design materials that are physically plausible since many useful BRDFs are not even energy conservative [2]. So it is often more accurate to talk about visually plausible materials.

Physical Plausibility vs. Realism

It's possible to design physically a plausible BRDF, respecting the three rules sited above, but still produce images that do not render real life phenomena. In a sense, physical plausibility is not a guarantee of a realistic material.
