CGTalk - A Sphere Problem

I have two spheres (or two other bodies) and want to relate them to each other. The relation is: if the first sphere is scaled up the second is scaled down or vice versa. I was able to do it only in a way that was scaling both bodies up or down, without the inverse function... Anybody knows if that can be done?

And the second thing is the skin problem; can the skin be used as a sculpt deformer for another skin or in any other way that would have the similar effect as the sculpt deformer? I have five blobs (sort of organic creature that moves and deforms and so on) and I want to put a skin around all of them so I would get only one living organism...

Thanks for all your effort!

You can use the Set Driven Key for the scaling and that way you'll only have to scale one of them. Just link each of the scale channels of one to 1/scale of the other. That way when one is at 2 the other will be at 0.5

As for what you're asking about with the spheres it sounds alot like metaballs which I don't believe maya supports.. Though a way you could possibly simulate it is to model the skin yourself and then make a number of different lattice deformers at the points you'd have the balls and animate the lattice deformers... Just a thought - I've never tried it so it may be a completely useless suggestion..

Hope this helps,

there is a maya metaballs plugin at highend3d.com.

how effective i dont know , i was never a fan of metaballs :)

but its a start.

for your first problem use a multiply divide node to reverse the scale values (multiply the first spehere's values by -1), and then feed the output of the multiply divide into other sphere's scale.

Sorry, my suggestion doesn't work. I tried using a reverse node as well, no luck there eaither.
