I recommend using the tracker low pass filters when recording mocap that includes jumps, dashes or stomping. As seen in this video wobbly feet trackers can be filtered to produce smoother looking motion capture.

State machine controllers often requires the root of each animation to be centered around the origin. For simplicity and best results it's recommended to enable the floor origin marker and ensure to always stand at the same location when starting a new recording.

APS includes a VR mirror, and if you look to the top right of the mirror panel you'll see some buttons to lock and level the mirror. The mirror is helpful especially when creating short attacks to ensure each attack always attacks the attacker (aka, the other you in the mirror).

For the tutorial I recorded a bunch of attacks in a single take, this video only shows one but in later videos notice how the mocap is simply one attack after another. This is so that later in Unity each attack can be cropped out as individual .anim files, and is much simpler than working with many separate mocap takes..

Once you've recorded a bunch of attacks it's a good idea to review the sequence in VR as the opponent would see the attack. This gives some idea of how realistic the final results will be.

This step involves simply exporting the mocap from APS to Blender, then from Blender as a .fbx so that the mocap can then be imported into Unity!

Now that the mocap is imported into Blender all that's needed is to export as a .fbx to the Unity project folder. 

In Unity it's necessary to set the .fbx to Humanoid for animations to work with Mechanim.  For this tutorial I used the included LuxVRM avatar, this avatar maps perfectly when the .fbx is set to "Humanoid", using other avatars may require manually mapping the bones, but that's it, you've got mocap in Mecanim !

As mentioned the .fbx contains a bunch of attacks including blocks and jabs, for this tutorial I am showing how to extract the .anim for only a single attack. In Unity's inspector look for the animation range handles and adjust the range until you have isolated just a single attack, then apply the range.

Now that you've applied the range for a single attack animation in the .fbx you can simply copy the relevant clip pressing Ctrl+D to extract the .anim file. First select the .fbx from the file browser and look for the mocap clip under the .fbx file, then select the clip and press Ctrl+D and a new .anim clip will be generated!

This tutorial does not go into detail about Animators and assume you already have a working Animator for your character. If so then it's simple to add the .anim we just crated by dragging and dropping the file into the animator editor window.
