I’ve asked this over on reddit, but thought it might be worth cross-posting: Is there a way to render negative frames in Blender 2.8? All I’ve found online is someone else asking my exact question in February, sadly to no avail. So I will go ahead and paste our question here:
I have a blender animation that I’d like to add frames to the beginning of. I’ve learned how to let the timeline allow negative frames. However, I can’t figure out how to render them in an animation. The “Frame Range” setting does not seem to allow for negative numbers?
Is this possible?
Alternately, is there a way to choose ALL keyframes in an animation- material keyframes, composite keyframes, and so on- without having to go in one item at a time and shift them by a certain amount manually. I know how to use the dope sheet to move the all the keyframes of the currently selected object, but not of ALL the keyframes in a given file.
Thank you all in advance!
Here’s what I could gather so far:
To move everything up in the timeline, deselect everything. Make sure the left icon is inactive: and the dope sheet will show you all animated properties.
However, this method leaves you with all physics, f-curve modifiers etc. that are not keyframed. You have to adjust those manually.
Entering negative numbers as Start Frame in the properties editor is not possible (maybe a bug?). If you have “Allow Negative Frames” selected in Preferences > Animation, you can move the timeline indicator to your desired start frame and choose Playback > Set Start Frame directly from the timeline panel. This way, you can render negative frames. You might need to update frame ranges in physic simulation etc.
