Marker Placement Toruble
Posted: Mon Feb 24, 2014 9:23 am
Hi,
After using Optitrack Arena for 2 years I am still having trouble figuring out how to get the arms to rotate accurately. We've just gotten used to dealing with the rotation problems manually but I keep looking into it hoping for a solution. No matter how I arrange the upper arm, elbow and hand markers the arms are always twisted in. It looks correct when in T-Pose position but when I let my arms down they always twist inward about 30-40 degrees too far.
The marker placement instructions during setup give even worse results. Rather than continuing to deal with it and do extra work fixing the rotations I am hoping to nail this issue once and for all.
Please help!
If I was animating a stick figure with no markings (or the default character template in Arena) it would look perfectly fine. But once you put the bvh files onto a character with textures its easy to see how off the rotations are.
