FBX issues

Ruz

I am really getting a bit frustrated with fbx format , particularly for animation keys.
It seems that the only way to accurately export the anims which include planted feet is to have a keyframe per frame. The keyframe reducer just randomly gets rid of keyframes that might be a important.
I need a way to bake all my ik/planted keys accurately before export( from 3dsmax to unity)
whatever setting i use unity has issues with floaty feet
ts a crazy as i am doing a simple idle anim, but at the end of every cycle the feet jerk about. works fine in max
anyone got any suggestions here?

What do the keys look like at the beginning and end of the animation? If they are the "same" take a look at the rotation values. I don't know how Unity does animation loops, but if the rotation values are not the same, it might flip out. (0 and 0, not 360 and 0).

its the strangest quirk as if I import the fbx back in to max and scroll through the anim manually then there is no twitch, but when I play the anim, the foot/feet twitches.
I am figuring its the fbx exporter for this reason

Lamont

Open the FBX file and take a look at the data.

TBH I should n't have to jump throgh hoops to fix this, the exporter either works or it does n't. I was just hoping that it was something in the exporter setting that i had missed
The same anims work fine in blitz 3d

Sounds like a different interpolator then. Blitz and Max might be using a bezier, while Unity might be just linear, or vice versa.

looking around on the forums, It does seem to be an issue, but its a pretty fundamental thing to me. The feet only move slightly, but it just irks me nontheless
It seesm that with fbx you can't export the exact keyframes.
You either have to convert it to a key per frame or use the key reducer, which is not very accurate

Lamont

Exact keyframes or fractional keyframes?

Ruz

exact keyframes as far as I am aware

seems like importing separate anim files is the way to go
usng @ animation. haven't full tested yet but seems promising
yeah this is my WIP .

edit
got rid of the sliding foot thing on the idle.
Seems to be best to load separate anims TBH
