Blender > Unity Animation Problems

Unity Engine

Hi, I’m currently working on assets created in Blender, rigged with an Armature and animated using the action editor. I have three animations called float, shrink and grow. I’ve followed several tutorials, tried exporting using the .Blend method as well as manually exporting my own FBX and files from the Blender scene.

The problems I’m having seem entirely random and sporadic but I’ll try to explain as best I can.

Here’s what should be happening. I should be exporting and saving from blender and my three actions in the action editor (which are correctly assigned to “F” as shown in all the tutorials I’ve seen) should appear in my Unity Assets folder simply and easily.

Now what actually happens is at the most I can only get two of my actions (Float and Grow) to appear in Unity depending on what action i have selected in Unity when I export/save. If I have float select at the time of the save I get both of these actions and this also happens if i have nothing selected. If i have grow selected at the time i get no actions and if I have shrink selected I get no actions. No matter what I do I cannot get my Shrink action to appear. I’ve even tried having the NLA editor open at the time of the save which seems to make random differences depending on my selected action at the time of the save/export

If that wasn’t strange enough I tried deleting the shrink action and creating a new one left with the default name of “Action” or “Action.001” or whatever and this had three different outcomes in Unity depending on what I have selected. Sometimes I will only get the “Action” animation file, sometimes I will get the previous “Float” and “Grow” files with the third action missing and then occasionally I will get all three. On this exciting occasion i went back into blender and renamed “Action” to “Shrink” in order to reanimate what was needed but once the action name was changed in blender it vanished from Unity on my next save/export.

This is maddening as every tutorial I’ve watched does exactly what I’ve done and everything runs smoothly.

If anybody could help with this strange issue that would be great? I can’t understand why some actions come through and some don’t. It feels very random and strange.

Cheers

Can you post the model?

I never create seperate animations in Blender when I’m going to be using that model in Unity. I always just put all my animations in one animation clip (the default one) and then split them in Unity. Unity - Manual: Legacy Animation system explains about splitting them. That always works for me, no matter what I have selected.

Also, I always manually export my models from Blender as FBX files. I just prefer to do things be hand, rather than let a program doing things I don’t know about handle my stuff.

Hope that helps!

The automatic splitting has to work. And the workflow is a lot more elegant with it. If you change the number of frames for the first animations, you need to adjust everything else. It is absolutely okay if you decided to go that way, but in general the other one is more practical.

Well it turns out the issue was that I was scaling my bones to 0. That gave some pretty strange results but replacing my keyframes with a scale value 0.001 and finding a quick workaround in Unity fixed all my problems!

Thanks for the quick responses though guys
