Title: CIE request: Second Merge option - MIX function
Post by: johan belmans on 2020-10-27, 18:31:38
At the moment the Merge function in CIE is there for merging multiple images from a distributed Rendering nodes. Therefore it uses an "ADD-function". If I am not mistaken.

It would be great if we can have an optional "MIX-function" for merging multiple images.
In this way it will be possible merging an image with a "region render" image or "render selected" image. And even get merged render elements.

The way it currently works is the same as Corona merging passes while rendering. It's not a simple "add" operation, but it's based on pixel weights instead.

Could you explain why a feature like this would make sense for you in CIE? What would be the advantage of this rather than using Photoshop or other post software?

Hi Maru,

The "MIX"-option (if technically achievable) would fit nicely in our current workflow.
We always save our renders as CXR's. And do basic post in CIE, save conf files for each render, next we save out EXR's and do further post in Photoshop.
In the situation you have to add an object to an existing render and you don't have the time to re-render the whole image. It would be great to merge the "crop render" with the previous render in CIE.
The advantage of doing this in CIE:
-is that beside the beauty pass, the render passes will be merged as well with the new information. This cannot be done in Photoshop or other post software automatically AFAIK.
-and furthermore we can load the previous conf file on the merged render, save as EXR and replace the beauty render and render elements in Photoshop.

Yes being able to merge renders with all passes in the CIE would be fantastic and a massive time saver.
