weird child ofset when moving parent geometry
on Jun 10, 2010 at 10:09:46 pm

Hello everyone,

I'm having a problem I've encountered before but have never been able to solve. Basically when I move my parent object it's children also move but to an offset position.

The project I'm dealing with now. My parent is polygon geometry, a radio. The children are a joint chain bound to an antenna and a hair follicle system to make the antenna move and bend when the radio moves or is deformed. When I move my radio on the x axis, the antenna bends beautifully but it also makes a bigger move on the x-axis. So does the joint chain.

It seems to be some sort of parenting issue.

Thanks,

Wouter

Skinned geometry should not be parented under the joint hierarchy. The joints already deform the geometry, and by parenting the geometry to the joint you move it twice, hence the offset. You can parent such geometry if you turn off 'inherits transforms' on the geometry's transform node.
