Corona Decals can be scattered on one or more surfaces using Chaos Scatter. This is useful for adding scene details such as graffiti, stickers, puddles of water, etc.
Corona Decals scattered on a stone wall. The decal material is using a diffuse map and an opacity map:
Corona Decals scattered on a surface, creating dents in it. In this case, the decal material is using displacement and self-illumination:
Corona Slicer Material
The Corona Slicer Material will cut through Chaos Scatters, too:
Cutting a hole through a forest? No problem!
And the other way around - if you apply the Slicer Material to a Scatter, you can use it to cut through other geometry:
Using a Scatter to cut holes on the surface of a sphere.
Corona Distance Map
Any map can be used to affect the scattering density (and other properties), including the powerful Corona Distance Map. A typical example is keeping some objects, such as trees or grass, away from buildings or paths. In the below example, we have a forest made with Scatter, and we are keeping the trees away from the building and the path thanks to the Corona Distance Map:
In this case, the Distance map is using the house and the path (a non-renderable box) as the "distance from" objects. Any areas close to those objects are colored black, and the areas farther away are colored white. This map is then used as the density map in Scatter:
The Distance map can be also used with animated objects, producing interesting effects, such as growth:
Remember that you can use Scatter with Cosmos to:
- Load Scatter presets which are included in Cosmos (either import them into the scene, which will create a whole new Scatter; or select an object and then import a preset - this will treat the selected object as the distribute-on object).
- Import any Cosmos model into your scene and manually scatter it.
See the Cosmos part of this article for detailed instructions.
