Custom Crafted Colorful Gemstone Collection: Diverse Cuts 03 Incorporating Genuine World Cuts & Authentic Materials Brings Unmatched Performance to Your 3D Creations 20 Custom Cut Digital Gemstones — real world cuts tailored for actual material reflective index ranges. These are genuine world cuts (I'm a gem cutter and expert graphic/3D designer) — if you design jewelry for real life, or virtual realms, these gemstones and materials bring what you need to add authentic colored gemstones to your masterpieces NURBS Based Geometry in the Provided Rhino Files (Rhino versions 5 & 6 included) Polygon Mesh Geometry in OBJ files — OBJ mesh geometry was derived from the Rhino NURBS originals and utilize the least number of polygons required to generate the gemstone's facet shapes 65+ Custom VRay Next Gemstone Materials — extensive research on specific optical properties for genuine world materials has been incorporated into materials for quartz varieties (amethyst, citrine, rose de France, smokey quartz, praisolite, rock crystal, rose quartz), beryl varieties (aquamarine, emerald, morganite, green beryl, heliodore), topaz varieties (imperial pink, imperial orange, imperial red, imperial yellow, london blue, sky blue, swiss blue ), tourmaline varieties (indicolite, rubelite, green, paraiba), garnet varieties (pyrope, almandite, spessartite, demantoid), cubic zirconia Includes Cut/Material Reference Chart — chart shows the scope of materials for each cut Notes: Scaling/resizing: ALWAYS APPLY UNIFORM SCALE when resizing a custom cut digital gem — each virtual gemstone has been optically designed for a specific primary material and range of secondary materials — that optical performance only occurs when the facet angles are aligned correctly so to avoid loss of optical performance always use uniform scale Size, Color and Optical Performance Guidelines: Gemstone materials obtain their color primarily from the refraction fog color if you need to lighten or darken a custom cut digital gemstone adjust the fog color and fog multiplier settings in the refraction section of the material (see the V-Ray Next manual for a complete description of how to make adjustments to the custom gemstone materials The same material will appear darker on larger stones, and lighter on smaller stones due to the amount of material the light rays have to travel through. If you've applied a material to a custom cut digital gemstone and it appears too dark adjust the using a lighter colored version of the same gemstone. In general, gemstones with a small number of facets are typically cut at smaller sizes, and gemstones with a high number of facets are usually cut larger (in the real world the smallest working size for facets is around 1 mm anything smaller is hard to do by hand. So if you want your gemstones to look realistic in your 3D creations, maintain the correct relative sizes
