Motion Builder 2016 Plugin

[David McDermott]

Has  Anyone had success with motionbuilder? VR recorded is working fine trackingmy headset and trackers but I cant connect with MotionBuilder 2016

I am running Windows 10
MotionBuilder 2016

Under network settings
it starts transmitting from Vr recorder and in Network it reads as "sending"

But in motion builder it fails to connect
It says either "could not get channel inform"
or "could not start device"

I also tried both as localhost and 127.0.0.1 no luck.

I made a rule to keep port 8889 open and also gave full permissions to VR recorded and Motion Builder but no luck

any other suggestions would be appreciated.

I also tried it in Motionbuilder 2017, same result

[Brekel]

Are the protocol (TCP / UDP) and the port (default 8889) in both the Brekel app and the MotionBuilder plugin matching?

Does it help to (temporarily) disable the firewall?

[David McDermott]

Yes, both apps have the same port.
I also tried them both set to 8899
and 7775

thank you for the quick reply

[David McDermott]

In windows firewall I made a rule for the OpenVr Recorder exe giving permission for all networks. , Motion builder alread had permissions.
I also set a port rule for 8889 to be open. - not sure if its safe to leave a port open?

Hard to say what is blocking the network signal to be honest, which is why I suggested disabling the firewall just to be sure that's not causing an issue.

Is there data in the Brekel app? It says "could not get channel information" in the MoBu plugin, maybe it can connect but didn't see any data?

[David McDermott]

I also turned off windows Firewall/defender and no result. I am looking into if there are further protections on our systems. I have also contacted our IT to see if the company firewall would effect it.its all local to my machine though.

As long as there are no mistakes on how I am setting it up.

[David McDermott]

It says "warning: connection reset by peer"  In Open VR Recorders log.

MoBu seems to connect it goes green and then, after processing for a while back to Red again.
I am glad to confirm I am not doing anything wrong ,I suspect it is our companies overzealous security software. I will wait for a reply from the IT provider.
Thank you for your help.

best regards,
David

I tried a different machine that isnt on our network and still had the same results, I completely turned off the windows firewall.

It is such a shame, the capture quality is really great!

[David McDermott]

Current Situation,

OpenVR works and records to FBX perfectly,  I recorded several test files. Great tracking Great quality.

Motion Builder Plugin  still unable to connect.
I.T. Completely disabled all network protection and motion builder was still unable to connect.
OpenVR Recorder changes its network message to "sending" so It must be making some contact with Motion builder.
But MB device still unable to connect.

We tried various ways to connect,
Varying ports,
using localhost on one machine
using two machines and streaming the data over the network
using Vive , using Oculus

Could you tell me the exact spec that you used to test the motion builder plugin?  Which version of motionbuilder? Was it as Localhost on a single machine? I will try and replicate your setup.
Thanks for your help.

[Brekel]

Testing was done on Win10 and MotionBuilder 2018 all running on the local machine and with default settings.

Will have to run some tests here to doublecheck if I can reproduce the problem.

[David McDermott]

Ok, thank you, I will install MB 2018 and try it out and report results.

Btw, I have the vive, controllers, plus 6 tracker sensors working in OpenVrRecord, works great.

[Brekel]

Looks like something changed in OpenVR recently, it can now address 64 instead of 16 devices, which is tripping up a safety measure in my MotionBuilder plugin. That was unexpected to be honest :)

Will see if I can get it fixed today and roll out an update.

Sorry for the inconvenience and thanks for reporting.

[David McDermott]

Thank you, much appreciated.

[Brekel]

Just uploaded v1.08 with a fix for this, when you start the Brekel app it should automatically detect a new version is available and offer to take you to the downloads page.

Again sorry for the inconvenience.

[David McDermott]

YAY!  Its working. Thanks for the super-quick update.

I did a test with just the head and it worked in motionbuilder.
Currently charging up the sensors, when they are ready I will do a full test.

Thanks again.

[Brekel]

I tested here with Vive and a controller before uploading.

Didn't have my trackers with me right now but those should work then as well.

[David McDermott]

I did a full test with the trackers and worked perfectly.
I had the vive, 2 controllers and 6 trackers.

We are getting another 5 trackers in the next few weeks, I will give an update on how it goes.

Thanks again.

Just wanted to Add a bit more info. I have been using the OpenVR recorder with 11 trackers at once. Its working perfectly. thanks
