Rendering & Materials #
News Features & Improvements
- We’ve added a Glint reflection shader that creates sparkling flakes and is useful for mimicking car paint, snow, and other effects.
- The Refraction shader has been improved. Absorption and Density have been consolidated into a Depth setting that can be controlled with a texture map. The Scatter setting can be controlled with a texture map as well.

- We’ve added a new ray-traced ambient occlusion effect to the raster renderer for more realistic occlusion.
- It is now possible to adjust Highlights, Midtones, and Shadows in the camera object’s post effect settings. Clarity or local contrast is available as well.

- Light color can now be set in Kelvin units by enabling the Temperature setting.
- Rendering performance has been improved with scenes that use multiple bounces in the ray tracing settings.
