    Hi Getnamo
    I surely don't want to rush you and I'm still impressed with your plugin.
    Do you think you'll have time to update the plugin to 4.9.2 cause I must have a build ready by the 28th to meet some clients...
    If you're too busy that's ok I just have to figure how to rebuild version UE4.9.1 from Github (I can only build version 4.10.0...)

    Thanks your amazing!

    Hi, would the latest UE4.9 version of the plugin work with Oculus runtime 0.7.0 ?

    Cheers
    Fred

    There are two possible reasons for this. One, if you don't have a VRPlayerController any hmd rotation may desync your rigged hands since your controller orientation is not decoupled from your hmd. The second is that the rigging uses compromises to match a mesh to your physical dimensions. It resizes the mesh arm length to match yours and this causes the hand to shrink, if this wasn't the case the hands would deviate more. If you want a more 1:1 rigged experience try the floating LeapEchoRiggedCharacter, which without needing to adjust elbows and such the rigging is able to match closer to the debug hands.

    If you can personally modify the rigging to have a better compromise, by all means make a pull request

    If you have a Mac, you should be able to just compile the plugin. You have full source and should be able to recompile it for 4.9 without issues. That said I'll include a final 4.9 mac binary when image hands make it in to the plugin (Mac isn't my main platform and I have an ancient Mac so unless someone takes up the Mac compile mantle it will always lag significantly behind the windows releases).

    Yes, all you do is follow the instructions in the github repo (and earlier in this thread) found under the How to use it - Blueprint without Convenience Content, Quick Setup heading. There you can forward/store all the latest leap motion tracking points to where you want to use them. You can also look into the LeapBasicRiggedCharacter blueprint to see how the more complicated rigging is handled using the intermediate AnimBody. Note that if you do not use the convenience characters, you will have to set your hmd mode from the component manually to be triggered when the hmd gets enabled (Optimize for HMD function).

    Not sure what the first warnings are and I will have a look at the invalid animation node one.

    You can safely ignore these type of warnings:

    this is emitted simply because the character is bound to the standard move events defined in third person templates. If they're not present, WASD and other movement inputs will simply not do anything unless you link them up in a way you want the external IM to work, see third person template for example of how.

    But here is an issue i ran into, and I cannot figure out how to solve this properly:

    I want to have the camera follow the animation. So when a different animation is played e.g. "sit", the camera stays at the same position relative to root.
    I figured attaching the camera to the head socket would solve this, which it does.
    However the LeapConnector must also placed relativ to camera/head to work correctly.

    This is an interesting problem and it has everything to do with how rigging is currently set up. The character is rigged such that you do not get micro motions from animation while still maintaining relative head offset and causing the body to turn and twist with your body leaning. It is a set of compromises to fit all the tracking criteria and may not be suitable for all applications.

    In VR, it is generally a bad idea to add animation motion to your hmd as it will encourage motion sickness, so if you wanted someone to sit you would play the sitting animation and keep the head IK(from camera/animbody) in the rough area where your head is while sitting. Your head mesh is automatically hidden so small mismatches won't be visible, large mismatches will however have the character bend in unrealistic ways like the one you have where the head height is much lower than normal.

    All animbody positions are given relative to the character root with Y-forward orientation, you may need to adjust this if you want a different kind of functionality. You could have the animation centered around the head not moving, or you could change the rigging to accommodate what you want to achieve. I haven't personally done a sitting character so I don't have a ready to go solution for this...

    Full character rigging in VR is a complex issue with compromises abound; a standard approach is to not have a body for this reason e.g. you can use the Echo hands character and not worry about fully body rigging at all, but I encourage you to explore and share your solutions so we can have one more thing solved in VR
