Cuban Link Bracelet with Diamonds 3D model

cgtrader

This is a production-ready Cuban link bracelet with diamonds. The model was made using Vray, and it features 2 procedural materials that do not require UVs for them to work accurately. You won't need UV maps at all if you are just working with these two materials. However, if you are not using Vray then you will definitely need a separate material for the diamonds, as well as one for the gold (no worries though - I'm happy to share my knowledge with anyone who wants it!). It works perfectly just the way it is! I kept things simple in the scene so that there are no render layers to worry about. There is a light setup with a sweep across the bracelet, plus a camera position already established. To give you a better idea of how the light interacts with the bracelet I have also attached a .mov file that shows it all off nicely. The render settings are optimized for an ideal 1920x1080 resolution but feel free to adjust anything as needed. This completely free HDRI (https://hdrihaven.com/hdris/) works great, so don't be afraid to experiment and try out some different ones if this one isn't quite what you're looking for! There's no rig because I tried keeping things very straightforward, with the intention of making it easy to get a sense of how all these components fit together. You might notice a Louis pattern in the .mov file, but that's just there by accident and is definitely not something I wanted to highlight - basically, what you see is that the image used for it isn't something that I own the rights to!

Now onto some super useful info on PBR shaders (and trust me when I say this works universally for all sorts of materials). Making a Gold Shader: - Set the Diffuse map to pure black. - For Reflection, you can go with something in that yellowish/orange range and make sure it has a value of 3.0 at minimum - otherwise things might look too bright and unnatural. - The Glossiness should be set around 0.95, and Roughness about 0.05. When making the gold material work seamlessly with other PBR shaders (especially those from popular applications like Substance Painter), don't forget to experiment with that Refraction Index range (it does make a difference) - anything between 8-11 works out pretty great visually speaking! To Make a Diamond Shader: - Set the Diffuse map to pure black again. - For Reflection, go all out and use something as pure white as you can get it (just make sure it's still around that 3.0 value). - Glossiness needs to be at its maximum setting, so 1.0. Roughness on the other hand needs to drop down as far as possible - that is to say about 0. So what happens is a much higher gloss than anything else; think of a real diamond shining right before your very eyes! - And of course Refraction and Refractive Index should be exactly opposite to Glossiness/roughness, hence white in value but IOR at 2.47 respectively (or slightly lower - doesn't affect how good the shader looks though).
