How to Design a Realistic 3D Diamond in Hana | Step-by-Step Tutorial

Quick Overview

The video tutorial demonstrates how to create a highly realistic, reflective 3D diamond effect in Hana by combining 3D shape extrusion, precise material adjustments (like high reflectivity and controlled refraction), and layering with blur effects to mimic complex light interaction.

Key Points: The diamond object starts as a custom, rounded hexagon shape converted into a 3D object using the 3D Shape effect (0:27-1:16). Material settings are crucial, involving setting Roughness to 0.07, Metalness to 0.20, Reflectivity to 3.01, Glass to 0.91, Aberration to 4, Refraction to 1.30, and Blur to 0.09 (2:17-2:38). Environment Map lighting is enabled using the "Studio dark" preset, with rotation adjustments (Y=2.89, Z=2.67) applied to enhance shine (2:43-2:47, 4:36-4:43). A second diamond layer ("Outer") is duplicated and used to create a sharp, reflective surface, while a third layer ("Inner") enhances internal reflection (3:13-4:15). A Layer Blur effect is applied to the duplicated "Outer" layer, set to 40% transparency and a Screen blend mode, with a blur of 29, to add surface highlights (3:44-3:56). Animation is added to the base layer using an Event that transitions from the Base State to the Inner State over 4 seconds with an infinite loop (5:05-5:25).

Context: This tutorial guides users through creating a complex, photorealistic 3D diamond effect within the Hana 3D design software, likely targeting users familiar with basic layer management and effects panels. The process involves building the base hexagonal shape, applying extensive material properties to simulate glass/diamond qualities, manipulating environmental lighting via an HDR image, and using layered effects (like blur) to achieve depth and realistic refraction.

Detailed Analysis

The tutorial begins by creating the base shape for the diamond, starting with a custom, rounded hexagon drawn using the vector tool (0:38-0:50). This shape is then converted into a 3D object using the 3D Shape effect in the Inspector panel (1:13-1:16). Significant geometry adjustments follow, including setting the Scale to 3.30, Depth to 210, Bevel Size to 52, Bevel Type to Flat (Rounded), Flat Round to 0.16, Smooth Angle to 1, and Subdivision to 12 (1:23-3:28). Next, the material properties are meticulously tuned to achieve a diamond-like appearance: Roughness is set to 0.07, Metalness to 0.20, Reflectivity to 3.01, Glass to 0.91, Aberration to 4, Refraction to 1.30, and Blur to 0.09 (2:17-2:38). Environmental lighting is applied by enabling the Environment Map with the "Studio dark" preset, rotating it slightly (Y: 2.89, Z: 2.67) to catch the light effectively (2:43-2:57, 4:36-4:42). To enhance the look, the base layer is duplicated, renamed "Outer," and its 3D Shape effect is modified, including adjusting rotation (Y=385) (5:37-5:41). A third layer, "Inner," is also duplicated and used to boost internal reflections (3:13-4:15). Finally, an animation event is set up on the base layer to transition infinitely between its current state and the 'Inner' state over 4 seconds (5:13-5:25), resulting in a continuously shimmering, rotating diamond effect behind the text "Diamond" (4:52-5:03).
