I was teaching a Blender class yesterday. One of the students apparently figured out how to playback his modeling history, almost like a preview, only it was showing the steps of construction, step by step.
He wasn’t sure how he had done it. I looked through the manuals and didn’t find anything to tell me how this might have been done. I could find how to step through manually, but not with an automatic looping through the steps, hands free. Any clues?
