Thank you, thoennes, I thought it was just me struggling with Poser rigging. Difference is I'm still at the 'Box Man' stage, and my wits can barely cope. Luckily, I'll be happy to adapt a few droids before daring to tackle anything more life-like.....

Doesn't help that eg Blender and MakeHuman seem to have very different ideas about rigging, and Poser's rigging tools would really, really benefit from VR...
