Mixed Cuts 04 — Custom Cut Colored Gemstones + V-Ray Materials That Deliver Real-World Results in Your 3D Creations\n\nCutting Edge Cuts & Unrivaled Materials Mean Unparalleled Performance in Every 3D Masterpiece You Design\n10 Custom Cut Virtual Gemstones— expertly crafted to match real material reflective index ranges, guaranteeing a real-world look. I know the secrets of gem cutting and 3D design; these gemstones and materials are precision-crafted for authenticity\nRhino Files Included - NURBS Based Geometry For Enhanced Detail\n Polygon Mesh Geometry in OBJ files — meticulously crafted from Rhino originals to optimize facet shapes, with a focus on efficiency and minimal polygon count\n100+ V-Ray Next Gemstone Materials— meticulously researched to capture the unique optical properties of real-world materials for a range of precious gems: 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), and cubic zirconia; ongoing updates ensure your creations always feature the most realistic materials available\nComplete Cut/Material Reference Chart Included — Your guide to matching the perfect material with each cut\nGuidelines:\nScaling/Resizing 101: Scale Uniformly— Always use uniform scaling when resizing a custom cut virtual gem — it ensures that optical performance is preserved, guaranteeing a consistent look. Optical alignment relies on facet angles being intact, and uniform scale is key to avoiding lost details\nPerformance Insights:\n Gemstone materials primarily derive their color from the refraction fog color; lighten or darken a gem by adjusting the fog color and fog multiplier settings in the material's refraction section (consult V-Ray Next documentation for more)\nThe appearance of custom cut virtual gemstones will vary with size, with darker tones on larger stones and lighter hues on smaller ones due to differences in refractive behavior. If your gemstone looks too dark, swap it out for a lighter version\nGeneral Gemstone Guidelines: Keep Size Relative\ — gems with fewer facets typically appear smaller; gems with many facets are more likely to be larger. Real-world working sizes range from around 1 mm and up (anything smaller is challenging by hand). To create realistic 3D gemstones, match the relative proportions in your design
