Powerful workflow tools

Corona introduces many workflow tweaks which will make your life as a digital artist easier.

Take command of creating your worlds with tools that make adding realistic details a breeze!

Chaos Scatter

Trees, grass, flowers, rocks, cars in a parking lot, fallen leaves — all of these add detail to your scene, but they can be tedious or impossible to place by hand. With Chaos Scatter, this isn’t a problem you’ll ever face.

Trees, grass, shrubs, and rocks are placed using Chaos Scatter, including limiting the trees from steep slopes, and carving out the roadway with splines

Chaos Scatter comes with a wide range of controls so you can achieve just the results you want:

  • Control and randomize scale, rotation, and translation, including limiting randomization to certain stepping values
  • Slope limitation, so that your trees don’t grow on cliffs ;)
  • Edge trimming, so you can keep those lawns – and more – neat and tidy.
  • Spline exclude/includes, to carve a path through your trees and scatter rocks along it, or limit foliage to flower beds with closed splines, etc.
  • Color the scatters based on the texmap of the object they are being scattered on. Perfect for creating patterned rugs, or variations in color on a lawn, etc.

The ChaosScatterSurfaceColor map/shader being used to color the scattered fibers on a rug.

  • Limit scattering to only be inside the camera’s field of view (Camera Clipping), to improve viewport and rendering performance
  • Extend scattering beyond Camera Clipping for correct shadows or reflections
  • Use maps to control density, scale, rotation, and translation
  • Create patterned scatters rather than random ones
  • Presets available in Cosmos, e.g. for grass, trees (presets include everything you need, such as the objects to be scattered and the Scatter itself)
  • 3ds Max only (for now) - edit individual instances after scattering, so you can move, scale, rotate, or even delete individual scattered objects
  • Preserve model Scale and/or Rotation
  • Control how the Scatters are displayed in the viewport to maintain responsiveness

Chaos Scatter also does much more! Read full details about Scatter in Cinema 4D or 3ds Max on our helpdesk.

Corona Pattern

Now you can tile real geometry over a surface, with the same ease as you’d tile a texture. Not only does this give you far more realism than you’d ever obtain with alpha, bump, and displacement maps, it also requires far less memory than those alternatives.

To get a quick grasp of when this is useful, think of things such as:

  • Fabrics, where those are made of knitted or woven strands
  • Wire fences
  • Jewelry such as chains

Of course once you get to grips with the tool, you’ll start to think of many other ways in which it can be used, raising the realism of your scenes to a whole new level.

Corona Decal

Markings on a road, cracks in concrete, smudges and dirt on glass — all of these are essential details in adding realism to your scene, and the new Corona Decal makes it easy to tackle these and more.

How does the Corona Decal improve on the old method of working with layered materials?

  • Easy to set up:
    You can move, rotate and scale them using the helper object in the viewport so that you can place them exactly where you want, or scatter them where randomness is required, or even animate them where it makes sense.
  • Stackable:
    It’s easy to stack decals, so your road markings can be affected by cracks in the road. This is controlled visually by how far each decal object is from the surface.
  • Fully supports displacement:
    Craters, cracks, bumps, dimples, carvings, and more. With displacement, you can have the realism you are looking for when adding these features.
  • Affect multiple objects:
    One decal can affect all objects it overlaps, regardless of the materials those objects use, so that your paint splashes can affect multiple objects. An include/exclude list lets you adjust this as necessary.

In this example, a patterned Chaos Scatter created this brick road, and the Decals apply over all of the individual instanced bricks without any extra work!

Corona Slicer

Sometimes, you want to see the outside and the inside at the same time. For example, you might like to slice off the top of a house to see the layout of the rooms within, or view a car with a cut away to show the engine inside, and so on. Corona Slicer will be your go-to tool for these situations!

Corona Slicer is a material you can apply to any object, turning that object into a “slicer” that will cut away geometry non-destructively at render time. You can animate this slicer object, and it all works without the inconsistencies of any sort of boolean operations in the host software.

You can control what happens to sliced surfaces, choosing to have no capping, or to create caps which can either use the material from the sliced geometry or from the material plugged into the Slicer’s Material slot.

Pro Tip: You can use the Rayswitcher when setting up the material, to make the geometry invisible to the camera but leave it still casting shadows. One use case would be wanting to cut away the roof of a house to see the interior, but not have the interior flooded by environment lighting. You can see a material set up and comparison of the results below:

Corona Lister

The Lister currently lists all Corona Lights in the scene, letting you access them and their parameters from one convenient panel.

SmartProxy: .cgeo

Corona comes with its own proxy format, .cgeo. The format is cross platform (you will be able to use it in 3ds Max, Cinema 4D, Chaos Corona standalone, or any other future platform). It uses compression, so it is small and fast to save, load, and to upload to renderfarms. Proxy models are always converted to millimeters and properly scaled when loading into scenes that use different units.

The proxy contains human–readable metadata at the beginning of each file, for example the name of the source object and its material, making them friendly to your pipeline.

Support for vrmesh Proxy Files

The Corona Proxy can load vrmesh proxies that contain only mesh data (additional features such as hair, levels of detail, particles, etc. are not supported).

3ds Max UI remains unblocked while rendering

Ever started a render, then minimized 3ds Max to get at something else on your desktop, only to find you can’t maximize Max again until the render is done? Ever started a render then wanted to check a setting in a different tab in Max, only to find that Max is locked? Those annoyances become a thing of the past, as rendering in Corona does not block the 3ds Max UI!

Cinema 4D does not natively support tooltips, but in Chaos Corona 7 and newer we have found a method for adding them anyway! We've started with tooltips for the Corona Materials, and if they prove popular we will expand that to other parts of the Corona UI.
