It would be amazing to see an in-depth tutorial, either a video or a written document on a complete and technically correct workflow with backplates (especially for automotive) in C4D to get the most accurate results. The backplate system now is pretty confusing and there's very little to no official up to date information on it anywhere.
Declining this as it is not a request for changes to Corona, but a request for a tutorial :) Do note though that I've made a note of this in the list of possible tutorials we have. Tutorial requests can easily be added to the forum, since they don't undergo tracking by the development team (which is why the Ideas Portal is used as feature requests for Corona itself). Thanks!
