How to offset all keys (without manually dragging keys) in Curve Editor?

worldpeace2040 — Sat, 29 Apr 2023 04:09:42 GMT

I would like to select all keys in the curve editor and offset them with a fixed value (without manually dragging keys)

Is there any way to do this?

A scripted solution to your request was posted by @Swordslayer here:

https://stackoverflow.com/questions/59278874/creating-a-maxscript-for-moving-keys

The actual script is shown below:

try destroyDialog ::MoveKeyTool catch() rollout MoveKeyTool "Move Key" ( group "Settings" ( spinner OffsetBySpn "Offset by" type:#integer range:[-1e3,1e3,10] button OffsetFramesBt "Offset Keyframes" on OffsetFramesBt pressed do ( local currentTV = trackViews.current if currentTV == undefined do return messageBox "Trackview window has to be open." local selCount = currentTV.numSelTracks() for i = 1 to selCount where (local ctrl = currentTV.getSelected i).keyable do moveKeys ctrl OffsetBySpn.value #selection ) ) ) createdialog MoveKeyTool

I can verify that it works on Max 2022.

In the "key entry" type in n +/-/*... something

Works for time and values.

There are also "Retime (all)" tool, Edit ranges, ...

Why is dragging manual and typing... isn't?!

Hey thank you for the script, I'll give it a try!

To answer your question, I have to edit 40 animations which all contains an undesired z offset. Manually dragging them might produce inconsistent results across these animations.

Thanks again for the reply!

Script is for time/frames offsetting, you, however, dont need to do anything with keys, just offset your object/s without setting any keys and whole animation will be offset.

Thank you for the additional tip.

I think I need to clarify that, what I wanted to do is to offset the z value of a particular bone (hip bone), the root bone location should remain unchanged.

In this particular case, I don't have the option to simply adjust the object's offset as that will alter the root bone location.

(I know I can adjust hip bone without affecting root bone with biped rig settings, sadly, the file I'm dealing with is a plain .fbx animation file without associated biped rig)

Frankly, I'm not sure adjusting keyframes via curve editor is the best (simplest) solution to solve this issue - if there are any other simpler ways to deal with my problem, I'm eager to give it a try.
