Hi,I noticed that animated transforms and Bones do update faster than osgAnimation::RigGeometry which is attached to bones. Is this a known issue ? Can this be fixed from my Side ?
This looks very odd in the case of a skinned character, and rigid ( MatrixTransform ) Eyes, as they move out of the character slightly but obviously noticeable.
Attached is a test scene, displaying the issue. The red cube is rigid transformed with 3 linear keyframes. The green cube is a RigGeometry transformed by a Bone which has the same keyframe ( z ) values . The blue cube is a child of the bone without animation or deformation.
Please note that the green cube is allways ( one frame ? ) behind. Thank you, Cheers, PP
