Improved Progressive Multi-Jittered sampling Same render time, with and without Path Guiding.

Note that while Path Guiding helps to render scenes containing simple caustics (e.g., water surface), it is not designed to be a caustic solver, such as MNEE, meaning it might not help render scenes containing complex caustics. The following images took the same render time. Important light directions are learned over time, improving as more samples are taken.įind it in the Sampling panel in Render properties. Guiding is supported for surfaces with diffuse BSDFs and volumes with isoptropic and anisotropic scattering. Blender Foundation and the online developers community present Blender 3.4, featuring path guiding in Cycles, new sculpt and paint masking tools, Geometry Nodes viewport overlay, new UV Editing tools, improved performance and much more.īlender 3.4 integrates Intel’s Open Path Guiding Library, adding support for path guiding in CPU to help reduce noise in scenes where finding a path to light is difficult for regular path tracing, for example when a room is lit by light coming through a small door crack.
