Renomi is Python driven Cinema 4D plugin that helps you organize your rendered image sequences and maintain your Object Buffer names.
By default, when you render Multi-Pass sequences to image files (Multi-Layer File is switched OFF in Render Settings -> Save panel) you end up with hundreds of files in one folder. For my taste, well, it doesn’t look good. I prefer every Multi-Pass sequence to be placed in it’s custom folder, like Shadow passes should go to Shadow folder, RGBA images should be placed in RGBA folder and so on. This way you maintain clean and tight file and folder structure. On the other hand, Cinema 4D does not rename your rendered Object Buffers, so you end up with general default naming like object_1, object_2. So there’s no way to know what object_1 refers to in your Cinema 4D scene.
