What is Chaos Cosmos?
Chaos Cosmos is an online asset library that includes high-quality 3D content. It allows you to browse, place, and render 3D assets in your projects. The asset categories span across Furniture, Accessories, People, Vegetation, Vehicles, HDRIs, and more.
Starting from Corona 8, the Chaos Cosmos library is included with any Corona subscription.
In Corona 9, Corona Decals are available in Chaos Cosmos as well as new Chaos Scatter presets.
How to import Chaos Cosmos assets?
Importing any Chaos Cosmos asset is very simple:
- Open the Chaos Cosmos Browser directly from the Corona Toolbar icon (or type http://localhost:30305/ in the browser)
- A new window will open, displaying the content of the asset library.
- Before starting browsing the content, make sure you're logged in.
- In case you're not logged in, please sign in using your Corona customer credentials (use your registered email address and your account password).
- Now that everything is ready, you can start browsing the content until you find what you're looking for.
- Once you've found anything that you'd like to import into your scene, you'll first need to download it. To do it, you can either click on the little blue "Download" icon in the upper-right corner of the asset preview image or click on the preview image and a new pop-up window will open where you can click on the blue upper-right button to download the asset:
The "Download" button on the asset's thumbnail. The "Download" button on the preview window after clicking on the asset's thumbnail.
- After the download completes, the little blue "Download" button will turn into a green "Import" button that you must click to import the asset into your scene:
The "Import" button on the asset's thumbnail. The "Import" button on the preview window after clicking on the asset's thumbnail.
- Finally, after clicking the "Import" button you should see a small notification in the lower-right corner letting you know that the asset is being imported:
- Now you can go back to 3ds Max and place the asset wherever you need it in your scene:
One thing that you should consider at this point is that the Chaos Cosmos asset will be imported as a Corona Proxy object.
By default, all assets are imported at origin (0,0,0) and have "Full mesh" display, which may affect performance when importing many assets.
Also note that all assets are downloaded in 3 different detail levels (LODs). You can locate different geometry files (.vrmesh) and their corresponding material (.vrmat) files in the asset folder.
- _3dh_ - high level of detail. This is loaded by default into CoronaProxy.
- _3dm_ - medium level of detail
- _3dl_ - low level of detail
If you want to load lower level of detail model, you can click "Load from file..." in CoronaProxy and the same asset's download folder will be opened, where you can quickly find other .vrmesh files.

There are also Scatter presets available in Cosmos. Find them in 3d Models > Presets or search for "scatter":
Here are some possible issues you may encounter and how to resolve them:
- I can't download the assets! (The download button is not visible).
Solution: Sign in using your Corona credentials
- The slave PCs cannot find the assets when sending Distributed Rendering jobs over the LAN.
Solution: Make sure the assets folder is visible to both the master and slave PCs. You can change the "Default Download Folder" by clicking the three dots icon and then clicking on "Settings". You should define a folder that is visible to all the computers through the LAN.
Note: make sure to change the same folder for all the computers in your LAN (master and slave PCs).
