To import the basic IK constraints into Maya, you need to insert at least one keyframe of any object, for Maya treats IK constraints as animation data, if there isn't any animation data, the IK constraints will be ignored.Īfter imported the basic IK constraints into Maya, you will find that the bones can't be driven by the effector correctly, this is caused by the wrong pole vector value. The add-on can import basic IK constraints from Maya correctly, but the exported IK constraints are not compatible with Maya. You can only use empty object as the target object, if you did not assign a target object, the add-on will create an empty object as the target object automatically. The add-on can export and import basic IK constraints since v4.1.10.

Because fbx files have files in them that you can't access directly. This gives you access to all the component meshes and to any armature elements. Drag that empty to a folder in the Project and it becomes a new prefab. For the model itself, create an empty object in the scene, drag the fbx into that empty, select it, right click: Prefabs>Unpack Completely. If there are animation clips in there select and duplicate them because once freed from the 'FBX box', you can edit those clips in Unity. Last recommendation: any fbx file you export FROM blender TO Unity, keep that fbx 'prefab' (actually it uses the prefab variant icon: box with stripe) in a folder named 'blender fbx files' or similar. (Autodesk stopped working on FBX a while ago, so that format is even more of a slippery beast.īlender is awesome - I use it a lot - and even though I've managed to figure out 'best practices' for going from blender to Unity and vice-versa, it never ceases to amaze me how often a new fbx issue manifests itself with models and rigs and animation.

A lot of asset store models with rigs and animation were made with 3DS Max or Maya. Unity tuned their implementation of FBX format to Autodesk's implementation and inner workings. There are several youtube vids out there that go through how to successfully export fbx from blender for use in Unity.Īlso, if you're going back to Unity after modifying a model made for Unity in blender, leave the Materials alone - stick to Unity for Materials and Shader changes.įBX is a wonky format. Exporting back to unity from blender is more fuckery.

Be aware that Unity uses a '+Z is forward and +Y is up' world coordinate system, while blender uses a '-Y is forward and +Z is up' coordinate system. The other fuckery will be on the import side in blender - if there is a rig and animation that you want to get to blender be prepared to play with the import fbx settings to keep the integrity of the bones' orientations. Just be sure to select Binary in the export options instead of the default ASCII - blender doesn't know what to do with fbx files in ascii format. For me, after importing the FBX Exporter package the FBX Export right-click menu item didn't show up until after quitting and restarting Unity.
