How to set up an Xsen suit

My group will be using motion capture for the animation for all the characters. Will be using an Xsen motion capture suit that is wireless. We will be able to capture accurate movements using the MTw trackers. The trackers will create joints tracking accurate movement. 

The first thing we did was get our volunteer, Faris, an Xsen shirt. It is important that the shirt is a tight fit, loose areas can affect the joints that leads to inaccuracies. We then attached about 17 MTw trackers to the designated joints. Making sure that every tracker is on by pressing the button that one of the sides. Starting from the top, we placed a tracker in a headband for the head. The shirt has a Velcro patch on the back of the t-shirt for the upper back where the shoulder would be and another and a little pocket inside of the t-shirt for the sternum. The other trackers will be attached using straps for the upper arms, forearms, hands, upper legs, lower legs which are placed under the kneecap, and the feet. 

With the Xsen motion capture software we will start a new motion capture session. Making sure that we set the configuration to full body, scenario we put a single level since we will be on a flat surface, and then added the height and foot size of the person that's going to be wearing the suit. After we are done adding the information it asks, we can place it to a folder, but it will not let you change the name when recording. So, we had to write down which recording we liked and what movements they were.  

Once all that is done, we will do a calibration. The computer provides instructions for things to do like walking around and standing still. As soon as its done calibrating we see in the software a model that is doing the exact movements of the person wearing the suit.  

Before we start recording, we must make sure we are setting the model in place to the correct orientation. Then we press the record button.

Part 1 Using Oculus lip-sync in Unreal Engine 5.3

Image
     In this week’s blog, with the help of one of my group mates Joaquin figure d out how to install the plug-in into unreal . We couldn’t figure out exactly why the plug-in would not install but Joaquin saw another OVRlipsync folder. He dropped the folder into Unreal’s plug-in folder. In U nreal   the OVRlipsync plug-in should show up in the plug- i ns folder called oculus lipsync . Once I found the plug in, I checked on the box and a window popped up to ask to restart the software for the pl ug-in to show up into unreal to be able to use it . Once that's all done I was able to use the oculus lip sync.        Starting off in the model BP in the component I added a OVRLipsync Playback Actor and audio .        Back to the content drawer in unreal I added a new folder and renamed it audio . In the folder I dragged and dropped a wav audio file. Hovering over the audio and right mouse click , I cl...

Updating the mouth

Image
     Last week I was working with the lip sync for the character . I added a new mouth for the character that looked a little bit cleaner and more simplistic. I also added the new audio for the character that we recorded.        First, I used photoshop and drew out the different mouth expressions. I used photoshop because I am a bit more comfortable and experienced using that software instead of adobe animate. I transferred the mouth expressions to adobe animate where I used the lip sync. From there I exported it out as a Png image sequence and imported it into unreal. I d id the same process where I used the media track in the sequencer to play out the lip sync.          I did run into a problem where the plane had a black background instead of being transparent. Usually when exporting a png it should be transparent. What I think went wrong in photoshop I painted the background black.      This was luckil...

Cleaning up the mouth animation in Adobe Animate

Image
       This week I was working on the final lip sync. Instead of doing clips of the audio for each phrase the main character says. We thought it would be easier if we put together all the audio we are using in one audio clip. For the process of the lip sync, I used adobe animate because it has lip sync. Where it automatically lip syncs the audio for me. As easy as it sounds, the auto lip sync isn’t 100 percent accurate. I would have to go over it a couple times making sure that the mouth doesn’t look too chatty, using unnecessary mouth movements, and making sure it aligns with the audio.      These are some things that I did for the lip sync in adobe animate when cleaning it up.       To change the mouth expression. I clicked on the keyframe that I want the mouth expression to change , clicked on the mouth that's on the scene, and on the right I clicked on the frame picker. A panel pops up with all the mouth animation that I added i...
