I recently made a model in Blender and I created 2 separate actions for my model (so it has 2 animations). Now for my game making in Unity, I like to have the “only deform bones” option checked when exporting my model to .fbx for critical performance reasons. However, when I check this option in the export settings for .fbx format, my animations do not export at all.
Here is the odd thing though, when I uncheck the “only deform bones” box, then my animations DO export properly. Unfortunately, I kind of need the “only deform bones” option, otherwise my game will lag very badly in Unity.
I created a model previously that worked just fine when exporting with the “only deform bones” option checked. The animations exported and everything. What could be causing my animations not to export properly when I have this option checked?
Note: I also tried exporting to .fbx format in two other versions of Blender, and the animations still will not export unless I uncheck the “only deform bones” option.
Yes, the fix is to have at least one key in the root of deforming bones. Blender don’t bake animations to FBX if the deformer bones dont have at least one keyframe.
