Text Version

1. Download and install: Visit corona-renderer.com/download to download the macOS or Windows version. After installing, open Cinema 4D.
2. Locating Corona in Cinema 4D: Corona can be located in the following menus: Main top toolbar, Material editor and Cinema 4D’s render settings.
3. Set Corona Renderer as your render engine: Click on Edit Render Settings, and in the Renderer dropdown, select Corona.
4. Add a Corona camera: This is as simple as adding a Corona Camera, using Corona > Corona Camera in the main menu.
5. Add lighting: Add a Corona Light (Corona > Corona Light on the main menu, or shortcut icon) to create a studio style setup for your scene. Duplicate light using CTRL+ drag (with the mouse) or repeat the steps above to create additional lights.
6. Interactive rendering: View real-time changes to your scene, lighting, material or objects position with Corona’s interactive renderer. Access it from the main menu Corona > Interactive rendering.
7. Multi-pass/LightMix: Click Corona > Multi-pass, enable the multi-pass check box, then click on the Setup Interactive LightMix button. This will display a pop up window, choose Individual Lights then press Generate. All your light sources have now been added to Corona’s LightMix
8. LightMix continued: With the interactive rendering window open and under the Post tab you can make overall changes to your scene including exposure, contrast etc. Under the LightMix tab, you can manually control individual light settings ranging from intensity, color output or Kelvin temperature.
9. Define when a render is complete: Click Edit Render Settings and under Corona’s General Settings tab set a pass limit of 20. Other options are using a Noise Level Limit (4% is good for final renders) or a specified time limit (e.g. 1 hour).
10. Enable Denoising: This can be enabled from Corona’s General Settings tab, simply choose Full Denoising from the dropdown. Our settings are set to default and denoising will be applied to the image once the render has completed.
11. Final render: With the VFB open and our render settings complete a final render can be made.
