Manipulating Animation Curves

[Anonymous]

Hi Everyone,

(Sorry for the duplicate thread)

I am quite new to the Fbx Sdk and am using it to work with animation curves.

There are a couple of things I am having trouble doing and would appreciate any insight.

Scale Keys/Tangents:
  - I can scale values/tangents, or keys without tangents, but not keys and tangents

crop animation
  - Trim start and end times
  - I can do this with python, but was hoping there was a way using the sdk that would be faster.

Apply Timewarp curve
  - I see the functions for this in FbxAnimUtilities, but am unable to get this to work

Set Key on frame with correct tangent
  - A bit of a longshot, is there a way to set a key on a frame while keeping the tangent?
  - Likewise is it possible to remove a key while maintaining the curve
  - Similar to how maya does this.

Thank you

Hey Alex,

I know it's been a year since you posted this, but have you solved your problem ?

I'm quite interested in croping my fbx animation in python; how did you managed to do that ?

Thanks,

Justin
