I have apparently accidentally recorded some editing I made to my project. I know I sometimes inadvertently hit the space bar while doing some editing to my scene. Until now, I was unaware that it could cause problems later on. Now, I have this Oktoberfest scene I'm working on that involves some mugs of beer. I have made some particles emitters to generate bubbles in the liquid. It worked fine when I was only animating one beer mug sitting on the 'floor'. But then I added a character (imported from DAZ), made many copies of the mug and experimented with positioning the character and the mugs.

THE PROBLEM occurred when I decided to hit the space bar to start the animation and generate some bubbles for a preliminary render before tweaking the lights and textures.

There were bubbles all over the place and objects appearing and disappearing, being moved randomly.

I tried to edit the animation but there is nothing to be seen there, no keyframes, no 'action' that I can select or delete.

Is there a way to 'reset' the animation completely or save the blend file without the animation data?

I can redo all the particle systems to correct what's going wrong, but that wouldn't solve the randomly moving props.

Here are just a few frames to illustrate the problem.First frame with particle emitters selected

Frame with bubbles being emitted away from the emitters

Frame with a mug appearing at a previous place

Frame with two mugs displaced

Yuo have Auto Keying turned on. This will insert keyframes every time you move an object and then move to another frame. Click it to uncheck it then select All your objects in Object mode, hover over the timeline and hit X > ⌦ Delete Keyframes to clear the lot and start again.

  • $\begingroup$ Thanks John, I thought I would be off the hook easy with that but it didn't work. I Unchecked the blue 'Auto Keying' button, selected everything in my scene and put my mouse cursor over the 'Timeline', clicked 'X', selected 'Deleted Keyframes'. Nothing happened. I played the sequence from frame '0' and all is the same. $\endgroup$

  • $\begingroup$ I think you'll have to provide access to your blend file in that case so that others here with more knowledge of animation than me can have a look. If it's not too large you can share it via: blend-exchange.com. $\endgroup$

  • $\begingroup$ Thanks again John, but my blend file is too big for blend-exchange. I made some changes in my Beer mug file. I'll try to delete all the mugs that are in the scene now and append a new one to see if all the moving history of those mugs in the timeline will disappear with them. $\endgroup$

  • $\begingroup$ I wondered about that. Although it's preferred that you upload to the official site lots of folk put their files on, for example, Google Drive or similar and post a link to it in the question. $\endgroup$

  • $\begingroup$ I've looked for free options to share that blend file but I couldn't find any that would accept a 100+Mb file. I'd need to work on the meshes and textures to make it smaller, but that is a process I am not yet very familiar or comfortable with. Remeshing, un-subdividing and all methods to lower polycounts. The textures I used are already only of 1 or 2k resolution. Unless those imported with the character from DAZ are heavier. That I don't know. So I went with the 'scratch the mugs and start over from there solution'. (I'll have to be careful not to accidently hit the spacebar though.) $\endgroup$

Just an update. I went through the process of deletion of the guilty mugs and re-appending and repositioning copies of the said mug from frame one. It worked. No more unexpected ghost appearances in the timeline. Lot of work though. I which there had been an easier way. In short: Since there was no keyframe recorded, none could be selected to delete them. Deleting the objects referenced in those inadvertently recorded moves effectively deleted the 'reference' as well.
