After rendering is complete, you can save the resulting image, including its multipasses, the Lightmix information, the tonemapping, and the denoising data into a single CXR file.
Note: Starting from Corona 12 Update 1, the CXR filetype is available for use in the Save section from the Render Settings dialog from Cinema 4D.
- Save a CXR file using the VFB 2.0:
Press the down-arrow button next to the save button in the VFB. This will bring up three options: Save, Save All, and Save CXR.
- Save a CXR file using the Legacy VFB:
Long press on the save button in the VFB. This will bring up two options: Save All and Save CXR
Note:
- If you click the "Save" button, this will save only your currently visible render pass in the format of your choice. So if you select the Beauty pass and click "Save", it will save only the beauty pass, without any other elements such as the LightMix, even if you select the CXR format.
- If you click and hold on the "Save" button and select "Save all", this will save each render pass as a separate file using the format of your choice.
- If you click and hold on the "Save" button and select "Save CXR", this will store all the information from the VFB (all render passes, including the LightMix, tone mapping, denoising data, etc...) inside a single CXR file. This file can be used to resume rendering later, post-process in the Corona Image Editor, perform denoising later, and so on.
Saving multiple CXRs is also possible. This could come in handy if you are rendering an animation or image sequence.
How to save multiple .CXR files.
In Cinema 4D's Render Settings dialog, go to the Save section on the left-side panel, then define the file's name and the location path where the files will be saved.
Finally, select the CXR file type.
Note: The CXR filetype extension in the Render Settings dialog is available starting from Corona 12 Update 1. Older versions of Corona can use the alternative method to save multiple CXR files.
Alternative method to save multiple .CXR files?
In the Corona drop-down menu, select preferences and on the pop-up window towards the bottom turn on Automatic saving on render end.
See Image:
Now an image will be saved after each render has completed its desired passes, noise limit, or if it's stopped manually.
By default, the images saved in the history will be stored in:
C: > Users > yourpcname > AppData > Roaming > MAXON > Cinema4DR(yourversion) > corona > history
