The update adds new procedural clouds and geometry replication systems and improves material overrides, the fisheye camera, and the display of Corona materials in the 3ds Max viewport.
Chaos Scatter 2, the next version of Chaos’s object scattering tool, is also due to ship alongside Corona 9.
Chaos Czech’s public roadmap describes Corona 9 as focused on “bug fixing, polishing existing features [and] code maintenance”, so it isn’t intended to be a major feature release.
Its two main new features will come as a little surprise to anyone who follows the development of Chaos’s other software since they’re also the main features in V-Ray 6, released earlier this year.
The first, procedural clouds, is based on technology from Enscape, with which Chaos merged this year.
In Corona, cloud generation is compatible with LightMix, the software’s relighting system, making it possible to render multiple sets of clouds at once, then blend them in LightMix.
The second is a new geometry replication system, called Enmesh in V-Ray, but known here as the Corona Pattern modifier.
It covers the surface of an object with repeating geometry, in a way analogous to tiling a texture, but unlike instancing, no extra memory is used by the repeating geometry: only by the source mesh.
Other changes listed in the roadmap, but not yet available in daily builds of the software, include a camera motion blur shutter curve, and support for out-of-core rendering for textures.
