I don't want those NLA Stash names showing up in the glTF export anyway. there are only 2 NLA tracks on the Armature, both of which have been stashed rather than pushed down, and are thus locked and muted with generic names that may be in conflict with each other and with the valid character set?Ĭharacter set and duplicate names should be irrelevant. As proof, I used FBX2glTF.exe to convert FBX to glTF, and the resulting file works perfectly, with all animations in tact. I know enough about glTF to know that there is nothing "special" here about how glTF does animations. The "All Actions" default is the behavior I want for glTF, too. FBX exporter has an "All Actions" checkbox option enabled by default, which (1) exports all actions in the file and (2) removes associations between specific actions and what objects they map to, so any animated object can use any action.

TBH, if you "couldn't understand half the things it" asked you to do, then maybe figuring out how to use the software would be a better first step to solving the problem. The Stackexchange link describes the usual workflow, not any special "fix".
TL DR: The screenshot and description look like user error to me.
By contrast, this add-on (and maybe the way actions are bound in the GLTF spec itself- Not sure) requires you to associate each action explicitly to the objects to which it's applied, which is done by placing them on an NLA track of their own, which doesn't seem to have happened here. There isn't anything in the screenshot that suggests that that's whats happening here. The only limitation is that each exported action has to map directly to exactly to one Action strip on each NLA track, as any greater number would obviously require re-sampling in some way or another. Multiple actions work fine last I checked, as long as you have multiple NLA tracks. This bug isn't lack of support for multiple actions. If FBX export is able to do it, and stackexchange has a list of steps to fix the issue, surely that means it can be fixed, or at the very least those steps can be automated into a single command ("Make NLA Tracks Exportable") or I think your screenshot is showing different channels in the the Action Editor rather than multiple tracks the NLA Editor, and in fact the Outliner panel shows that there are only 2 NLA tracks on the Armature, both of which have been stashed rather than pushed down, and are thus locked and muted with generic names that may be in conflict with each other and with the valid character set? Here you can see that if I use FBX export the exact same blend file, all the NLA animations show up fine in Unity: Related stackexchange post explaining how to fix this manually but I couldn't understand half the things it asked me to do: Since it hinders the adoption of glTF and it's been open for two years, I think this should be considered a bug not an enhancement. The file exports to FBX correctly with all animations intact, so the issue clearly lies with the glTF exporter. (If it would be helpful for debugging, I could try to share the blend file.) I confirmed this by opening up the resulting glTF file and there's only one item in the "animations" array. It looks like this blend file does use NLA track, but only one animation is being exported. Here you can see an example file with all the actions: (edit - I’m using the Blender 2.I'm trying to help a user export content to glTF and they are hitting a wall. Or maybe do you have a completely different solution to do this that I am not seeing? Also it seems that constraints sometimes don’t work for me as intended all the time (but I might have to try a little more here). So far I seem to need to create separate empties to follow the animated objects and then export those.ĭepending on the complexity of the scene and how easy it is to manage this is not really a good solution. So: saving empty locators instead of the whole animation with meshes and materials etc. Unity seems to work with empty objects for this purpose. Is there a way to do this directly from the animated object hierarchy itself? What I want to save out, though, is the animation alone so that I have a separate animation file without geometry. Now, when I am animating an object it sems that I can only export the animation attached to the object, right? I want to bring them over to Blender to create an animation to import back into Unity. Say, I have a scene with a prefab object consisting of two doors and a lock as subobjects in Unity.
Is there a fast/easy way to export only animations into an FBX file coming from an object animation?įor the sake of this thread let’s keep the setup premise here simple:
