Kat Walker’s Studio I & II Blog

Up to this point I seem to have mastered the art of capturing the five fingers and have moved on to the post processing. I was able to capture the sound and have it synced to the animation on Monday and have been attempting to animate the keys. This will definitely take a lot more time than originally planned.

The weekend went well. I talked to my sound designer, Clayton De Wet about recording a performance. He said films usually record the audio first and sync it up during the performance. When I get to the point of having a performer come to play the piano, I will have him or her go to Clayton’s studio first to record and then we will sync it as it is played in the motion capture studio.

As for the skeleton my modeler told me he would be finished this coming week. He’s a bit late on the deadline as I was expecting it this weekend.

Also last Friday I met with Matt Ward from Image Movers Digital. I spoke with him a lot about motion capture and what they’re looking for on a demo reel. He told me the default characters or a basic character in MotionBuilder would work fine. When I told him I was bringing things into Maya he asked why I even took that step. What they look for in demo reels are the moves not the rendering and painted weights. He told me not to waste my time. With that advice I’ve decided to bring the piano and possibly the character into MotionBuilder so that I can render there instead of in Maya.

He also told me that the hand capture was a great idea. It is one of the few things not perfected in the industry and if I could do it with a 12 camera setup that it would look very good for getting a job. He also said that facial or animal motion capture would be a good thing to try.

As for my work I managed to get a working piano playing actor. The movements do not translate very well to the Mia character and I may go ahead and just render with the actor. I’ll be working on animating the keys on the piano with the actor and then possibly moving on to the character. The problem is I need the character from my modeler before I can begin fixing the hands in Maya. The animation comes from an FBX and is merged into the scene with a character already in a TPose. I need the character’s exact finger length to animate the piano in Maya. For now I will animate it in MotionBuilder and get everything working there.

I’ve managed to bring in the piano to MotionBuilder from Maya. I also have playblasts of my coneman with the applied animation from the Mia skeleton.

I have continued to work with the Motion Capture Data from Sunday and have come across a significant improvement to the thumb. The wrist still pops but the thumb pops very few times.

I’m currently looking into getting a trial of the PeelSolver Plug-in for Maya. PeelSolver allows the user to by-pass motion builder and attach the data to a skeleton right in Maya. The issues I am having in MotionBuilder are with attaching the fingers to the actor. I’m hoping that this plug-in would allow the data to be better read by the final skeleton.

Today’s capture session went well. Being at the computer was much easier than directing someone at the computer and being in the suit. I was able to get several decent captures and I have been working with them since we finished up earlier today.

The past two days I have been working first on the Fur Elise capture and then on one of the Mary Had A Little Lamb captures.  The more and more I worked on the Fur Elise capture the more I noticed issues besides the jittery leg.  After working in MotionBuilder with the FCurve editor on Wednesday I realized the hands weren’t level.   For some reason when I applied the motion to the Mia character (whose skeleton I use on my Maya models) the hands became uneven.  This problem is not fixable because keying the hand defeats the entire purpose of the glove exercise and it would be near impossible to key the subtle hand movements of a real human.  Therefor I decided that I would go ahead and simplify the process and get a one hand capture working before I go back to the two hands.

At this point I started working on a Little Lamb capture.  At least 20 or 30 times I reworked the location of the markers on the actor and debated on different sizings of the actor.  I have two examples below of the type of issues I’m running into.  This weekend I will continue to work with the Little Lamb capture.

Also I spoke to Dave Kaul about moving the cameras and he told me I need to speak with Anthony at the cage about that.   If I cannot get the Little Lamb capture working, I will be pursuing the movement of the cameras but will also go ahead and recapture without moving them on Sunday.  I have a friend that can play a basic song on the piano and he will be getting in the suit so that I can ensure a clean capture and hopefully a quicker cleanup than my past captures.

I also spoke with my modeler and he will be modeling the skeleton and painting its weights in the next week. After that he will be painting the weights on my alien character. The piano will be played by the skeleton until the alien is finished and working properly.
