Simple but Awesome revelation from Malcom Gustave from www.ikfk.com who gave a masterclass in rigging.
It completely makes me see things in Maya so much simpler and helps understand offset groups and zeroing out groups so much easier to explain.
When an object in Maya is created, you can consider it to be parented to the world because it is taking its transformation relative to world coordinates 0,0,0.
So when a child is parented, its transformation values will be then relative to the parent and no longer the world.
THIS is the key to offset or zeroed out groups.
What I tell myself everyday.
To all the people watching, I can never ever thank you enough for the kindness to me, I'll think about it for the rest of my life. All I ask is one thing, and this is.. I'm asking this particularily of young people that watch: Please do not be cynical. I hate cynicism - for the record it's my least favorite quality, it doesn't lead anywhere. Nobody in life gets exactly what they thought they were going to get. But if you work really hard and you're kind, amazing things will happen. I'm telling you, amazing things will happen." - Conan 'O'Brien
