![]() Thin glass with roughness, like frosted glass, can now blur refraction as well as reflection, and also correctly simulates bouncing within the thin glass.Īrtists using the Sky Model can more accurately depict a digital sun and weather from hills, a skyscraper or at sea level in Corona Renderer 7. Rough glass now produces more realistic reflections and refractions – even when using the same values, the new glass may look different and more correct. Instead of trying to manage individual fibres across the surface, users can adjust the new Sheen parameters, which make fabrics render faster and easier to control. The Material Sheen effects take into account the look the fibres of a fabric give surfaces. ![]() Clearcoat also has an independent bump map, allowing you to create rough surfaces with a smooth, rippled or other clear coating over the top. Achieving the same effect with the earlier legacy Material needed several layers that could be hard to control. Clearcoat and SheenĬlearcoat in the Physical Material has an absorption layer that affects the colour of Diffuse Reflection and other aspects of the base layer in a realistic way. Controlling the look of a metal can now be done by adjusting the Edge Colour and then fine tuning the end result by eye, or by using Complex IOR (index of refraction) for physically correct scenes. As Roughness instead of Glossiness is now the default, users switch to Glossiness and Specular when needed. Materials are now defined as either Metal or Non-metal to make sure that only the correct, industry standard parameters are available for each material type. These include Sheen parameters for creating photoreal fabrics, and Clearcoat lacquer. From there, the Physical Material comes with various features for greater control over looks. These changes make it possible to set up initial hyper-realistic scenes in a few minutes. Corona Renderer 7 for 3ds Max makes updates to the Corona Physical Material and Corona Sky, with improved effects that increase realism in 3D scenes, and achieves faster render speeds.Ĭorona’s Physical Material now has 35 new presets for glass, metal and fabric, with a new Oren-Nayar diffuse model.
