How can I know what render engine a file is made for? I'm an intern in a lab and they want to use blenderfiles for generating stimuli for a visual perception experiment. The previous intern got started, and now I need to finish. Because of how this experiment will be set up, we need files all made in the same engine. I know that you can see the engine on top of the screen, but I think she changed it sometimes to a different engine, and now I don't know the real engine anymore.
First, unless the previous person used an external engine, when the file is loaded, whichever file is being used for the blendfiles will be displayed. But more fundamentally, it would seem to me that all of the files just need to have the same engine, and you could reset any that don't conform to the desired norm.
