how to retargeting avatar with iobt

I'm having the exact same problem and are looking for answers - if I find anything I will let you know 🙂

Ok So I figured it out. If you followed the tutorial its seems the default config on the scripts doesn't quite seem to be correct and caused some issues with retargeting. 

If you look in the packages folder. For me it was : Packages/com.meta.movement/Samples/Prefabs/Retargeting/
then use the prefab ArmatureSkinningUpdateRetarget.prefab

This is an example using the prefab from the package : https://youtu.be/-q8Ci5oLX4U
I then imported my own model and like for like copied all of the settings from the original prefab. I didnt really spend much time tweaking this and also messed with some of the settings but seems to be working fine : https://youtu.be/7i4Ph-OhiiM

Hope this helps you out 🙂

Yeah I believe the models should scale accordingly based on your head height when its running on your headset.
I'm pretty new to VR myself so don't quote me on that. The best thing to do is test with the avatar provided and then replicate it with your new model using the prefab.
