Motion-capture with rdm tools v2

Create a custom rig mapping with Human IK for rdm

2020-04-15_20-14-40.00453 — Open Human IK

2020-04-15_20-14-40.00687 — Lets Create a Custom Rig Mapping so we can use our own custom rig with HIK

2020-04-15_20-14-40.01466 — Now we use some script we have to create our description and custom rig controllers

2020-04-15_20-14-40.02410 — go to: maya>Version>scripts>RdMToolsV2>RiggingTools>Mocap and open HIK Definition .py

2020-04-15_20-14-40.03105

2020-04-15_20-14-40.03626 — Execute the code choose yous spine version Ik or FK

2020-04-15_20-14-40.04535 — A window should open so you can choose your spine version vot the custom controllers setup

2020-04-15_20-14-40.05401 — Ideally our rig must be in T pose... yellow means its OK but not perfect (This one is A pose so its yellow 'D:' )

We already make changes in the first step of the tutorial. If something is not working just go to the orignal file and sart changing its offsets. Remember Z is primary, Y is Secondary and X is twist — Now we need to adjust some stuff so its moves better... in the contrllers we can have some offset for the controllers. in most cases this changes works but fell free to change more if its not working properly (Z is primary move, y is seconday and x is twist)

Custom HIK Mapping for the mocap

With a new maya scene we can create a custom mapping for another character 1

2020-04-15_20-14-40.15907

Now open the mixamo definition in the script editor and execute it so we can have the definition for mixamo rig (be aware of namespaces, take a look at the code so you can see how your pieces should be called)

the script make sure the mocap data its in T or A pose at frame -10 so we can define it perfect with HIK

Apply the mocap to rdm

Lest load the rig as a reference so we can make changes and be more clean in our pipeline

Now we must have 32characters in HIK

We will be using the rig as the main character

and the mixamo as the source mocap data.

this now be moving. Just be aware we dont connect the polevectors or the base controller to anything so them wont be moving. you should move them if needed

now we have mocap :D — now we have mocap 😀
