Animate FilmWidth/FilmHeight with fbxsdk

[Anonymous]

Hi. I have a question about using fbxsdk.

How can I create AnimationCurveNode for FilmWidth and FilmHeight for FbxCamera? I would expect to use something like:

auto curve = camera->FilmWidth.GetCurve(pAnimLayer, true);
auto index = curve->KeyAdd(pTime);
curve->KeySetValue(index, value);

That works for FocalLength but not for FilmWidth.

Documentation says that those properties are read-only and function void SetApertureWidth(double pWidth) should be used instead. However I do not understand how can I create keys with different values. And I know that's possible because Maya can export fbx files with animated film size.

ok I actually found out that it is possible to add keys to curve as shown in my code sample above. But property need to be explicitly marked as animatable beforehand:

camera->FilmWidth.ModifyFlag(FbxPropertyFlags::eAnimatable, true);
