Hi guys,i have some works need use NatNetSDK steaming data to control skeleton in ue4.

now is the question.

i have to use some data in NatNetSDK to control root bone's(IN UE4) rotation&position.
i see that NatNetSDK data has a root bone names Hips.but in UE4 , root bone is between two
foot.

are there some data i can use? or must i calc the root bone's(IN UE4)s ro&pos?

Hello MaiMaiSad,

Thank you for reaching out to the community regarding your NatNet questions.

In Motive, the root bone for the skeleton is the Hip segment. I do not believe any kind of global root is provided, so this is something you would need to calculate

This may be all there is to it, but if you have any further questions please feel free to reach out to us at help.naturalpoint.com

Best regards,
Steven

Thans a lot for ur help,steven!

i see the plugin your team have done in Motive.

is there any Mature program make the data into UE4 skeleton real-time?
(i have see the sample in NatNetSDK,and your plugin in UE4,but isnot about skeleton,is about rigidbody.)

My pleasure MaiMaiSad,

Unfortunately, our plugin is only for rigid bodies. The skeleton data can be streamed as rigid bodies, but I am not sure of any setups, in Unreal, that can relate rigid body data to skeleton data.

Our NatNet SDK does give access to skeleton data, so it is possible to develop an application of your own.

Cheers,
Steven
