How does blender nla animations export to fbx unity

Here's the smooth position animation data of the Hand L IK Goal bone as is in Blender before export. The latter two have Inverse Kinematic limits placed on them in the Bone tab in the Properties window in Blender. The shoulders are not part of the IK chain, just the upper arm and the lower arm bones are. The problems occurred mainly in the shoulder, upper/lower arm, and hand bones. However, the hips, spine/chest, and neck bones were all fine! Those bones had no jitter in my animations. For the export you have to select the following: When you open your FBX in Unity there is only one action for each object.

You have to push the action down to a new strip: Open the NLA-Editor and push that button next to your action. The IK goal bones had position animation data, and then the other bones end up with resulting rotation animation data. However, when I Export it to FBX and open it in Unity I have the same problem. Now that you mention it, most of the curves in the FBX file are rotation because I use IK for the feet and arms with non-deform bones that are not included in the export to have a less cluttered hierarchy. rotation curves in particular), or just any/all of them? Could you include a screenshot of these? To help narrow this down a little, when you say that there are little jumps/peaks, is this on any particular curves (i.e. I really hope this can get fixed or circumvented somehow - my games depend on this! So when I do this, everything is exported great, the NLA strips are nice and organized, the mesh is perfect in every other way, it's just that the animations end up with this weird (and very obvious) jittering and twitching throughout the entire animations.Р”Р„nyway, let me know if there's anything at all I can do to help. Scale: 1.00 (Not applied, however! The button to its right has been unchecked) Then with that selection of just the knight character and its armature, go to File > Export > FBX (.fbx). In the 3D view, you can press Shift + G to select all of its children, and then re-select the parent empty object again. Select the parent empty object I created called 'Castle Knight'. These results have been observed when importing that FBX file into Unity (Unity 5.x, 2017.x, and 2018.1's beta versions all alike), even when all animation curve re-sampling and compression has been turned off.Р”В®xact steps for others to reproduce the error The exported data, however, looks almost as if it was an audio signal with noise - there are somewhat 'random' little peaks and crevices that cause terrible jittering in my character (most notably in their arms and legs) when I export my character to an FBX file and turn on 'Bake Animation' (so the FBX file has the animation with it). In Blender, the position and rotation curves, using Bezier interpolation work great and are smooth as expected. When exporting animations containing position and rotation animated data on armatures I prepared to map nicely to Unity's standard Mecanim Humanoid, the exported animation data does not really reflect the animation curves properly in Blender. Specifically, broken currently using Blender v2.79a (Date 10:41) Total Available Graphics Memory: 16302 MBР”В«roken since I started using Blender (roughly v2.77) Processor: Intel(R) Core(TM) i7-6850K CPU 3.60GHz But the other two (of walk/jog/sprint) treated with this method will not export properly if they aren't the currently selected action.Castle Knight - Backup. If i do that with an action, and then keep it selected/active on the armature while exporting, then that one, and only that one, will export fine. Pressing the + button to create a new action which is a copy of the current one:Р”Вoes NOT work properly. Works, and the result exports successfully (this is pretty quick and easy) Selecting all keyframes, copying them, creating a new action, keyframing all channels in frame 0, and then pasting all keyframes: Manually copying, pasting and keyframing poses into a new action: Binary is the newer FBX version.Р”Р„s per Fab4's recommendation, i've tried recreating the apparently bugged walk/jog/sprint animations. Р”Р„scii is by the way the older FBX version, which could explain your trouble. You could also try to use external tools to export proper FBX. What you could try is to use this script for rotation issues: Р”Р„nd you could try to use the newest Blender developer version, which can be found here: And from now and then they break some things. The problem here is that the developers always reverse engineer every new FBX version while other companies simply grab the official FBX SDK from Autodesk, and have a working version. Hm, the Blender pipeline becomes more and more problematic with FBX. I use to primarily model and animate in 3DS max and not once did i ever have a problem importing an FBX into unity from it. Is this a Unity issue or a Blender issue, Ive been attempting to fix this for hours but everything Im finding online isnt working. Yes it's reported since version 2 regularly. And this is the animation tab with no way of editing the animations length or loop.
