AI Enhancer in Corona Image Editor?

I am afraid it is currently not possible to submit an image for AI enhancement from the Corona Image Editor. If you would like to have such an option, please submit a new idea at https://chaoscorona.ideas.aha.io/

If I upload the .png or .exr image directly to cloud collaboration, I can only upscale it, but I don’t have all the other options.
I don’t know how to do it?

A “regular” PNG or EXR image can’t be enhanced. You need to either use the AI Enhancer button in the VFB or click the small arrow next to the Save icon and pick “Save for AI” - this saves an EXR image which can be uploaded to Cloud.

As I understand, you would like to do the following:
batch render in 3ds Max (e.g. multiple camera views) > edit the resulting images with CIE > enhance them in Chaos Cloud
Is that right?

I was about to log this in the Ideas Portal when I noticed that you have already done that. Great, thanks!
