But the geo still remains static, seems that the deforming information still cannot read by Unity. Also, the animation take contained in this pig FBX, whose bones created in Houdini (recognized as controllers in Unity and have the right hierarchy) have keyframes that can be seen in Unity's Animation window (I made the bake constraints operation on all my bones before exporting). I compared it by another animated character FBX created in Maya and exported to Unity and happily see their hierarchies are the same. The FBX generated from the shadow_rig tool can be recognized by Unity now, and it's controller hierarchy is (I assume) correct.

shelf tool in your $HOME/houdini17.0/toolbar directory then in Houdini you should be able to add it to one of the existing shelf sets.Thank u very much Goldfarb! And also many thanks to the shelf tool works, and I've achieved partially success while exporting. Now I'll re-upload my files, if it's convenient to u can u please take a look foe me once again? I'll try baking first and do as u say to export 2 FBXes. cheers! rob Thank u very much for ur suggestion! Yes, exactly in Maya the exporting pipeline runs as u say, and once animation is baked on bones it can be exported together with deformed geos as a singe FBX. For us the whole import geo and add a rig is still something of a struggle atm, mostly due to the ‘newness’ of things. After importing both files into Unity, you should see a animated character in the preview window when selecting the animation FBX. And yes, you should animated on the rig controllers, unless there's something really specific that needs animation on the bone directly. Be sure to ‘bake’ the animation on the bones export, so Unity knows what to do with it. But normally (in Maya) you would export the (static) bones + geo as a separate file, and just the bones for the second file. RobW Cannot open the rar file, it is corrupt or created with something else than Winrar? We're looking into this as well atm, and could be a interesting discussion to have.
