Challenges and optimization strategies It’s important to remember that SSS may appear a bit off due to issues such as overlapping faces, solid objects that are not closed (holes, unwelded vertices), lack of thickness, and incorrect scaling. To prevent this from happening, try not to rush when working on a project. Ensure your geometry is clean by taking regular breaks, being observant, and fixing any object irregularities you spot. To wrap it up Substance scattering is an excellent tool for adding an extra level of photorealism to your renders. It takes into account the physical properties of light and the way it interacts with each unique object, preventing them from looking plastic-like and creating a realistic representation of the scene’s surroundings. We encourage you to experiment and play around with the different shaders in V-Ray and explore which ones incorporate best into your workflow. FAQs Should I use subsurface scattering?  You should definitely use SSS, especially for translucent objects. It can help make a huge difference in creating realistic skin, wax, marble, liquids, foliage, and more. What objects have subsurface scattering?  Any semi-translucent material where scattered light diffuses inside — skin, wax, marble and jade, fruits, milk, juice, leaves are just some examples. How can I improve my renders using subsurface scattering?  Use SSS for the right materials, and experiment with different shaders to see which one gets it just right.  Does enabling subsurface scattering increase render time?  Yes, but if used smartly, not by much. You can manage performance by using it selectively, and keeping in mind it’s a trade-off between time and quality. Why is subsurface scattering important for 3D artists?  SSS mimics how light interacts with real-world materials through scattering. Without SSS, materials lack depth and look artificial — skin looks plastic, wax looks flat, and characters, close-ups, and product shots lack photorealism.
