not sure if this post should be here or in Blender Dev section, but its tighly related to rendering so I put it here.
Right now when I select a non multilayer file format in the output properties (png, jpeg, exr, etc.), I only obtain a single image per frame on disk: the combined image, from one of the view layer (the last one from the dropdown list of the image editor that appear when I press “Render animation”). All other images are in memory, visible from the image editor, but not written on disk.
Is there any option in Blender to write all rendered images on disk ?
If not I will implement this and I’m thinking of adding a checkbox to enable this in the Output properties panel, what do you think ?
Also I know I can do that with FileOutput nodes but due to limitations with EXR metadata related to cryptomatte (see https://developer.blender.org/T64953) we are planning to use the main output of Blender.
