XPresso help….multiple object axis?
Hey I’m trying to create something using xpresso and I’m getting stuck. It comes down to 2 different parts:
Part 1:
Basically I have a group of objects that all need to rotate around a fixed point, a null object. I want to drive the rotation using xpresso. These objects aren’t rotating around their own separate object axis, but rather the object axis of my null object. They need to move together like they were grouped…Part 2: BECAUSE I can’t just group them together, because some objects need to belong to multiple groups. The next part of my goal is to have another different object axis that the same objects could rotate around.
I’m thinking there is a way to do this in xpresso. Anybody have any idea on part 1 or part 2. Any help would be appreciated.

without knowing your setup it’s tough to know if a solution exists in xpresso or otherwise but could you have a ‘master null’ that everything is under that can do your rotation then have other groupings under that or is it more complex yet?

I have different objects arranged in a cube, they are evenly spaced and need to rotate similar to a rubix cube. Each object belongs to multiple rows, so it may need to rotate around 2 different points, like how a rubix cube can turn in different directions around different points.

did a google search…
this is interesting since it just uses the grouping you get by selecting a number of objects and not any fancy setup, the only question then is how to quickly select the bits you want.

That is the right idea… the parts need to be able to rotate around different points as a group, not individually.
step 1 is that I can’t get multiple objects to rotate around my null object’s axis in xpresso, which I can’t seem to get.

I don’t know if it’s possible with Xpresso, but it’s definitely doable with the Constraint Tag in Parent mode:
