Retrieve objects parameters in an ordered way. Dec. 11, 2018, 2:07 a.m.

Hi tanto.
Multiple Object Merge SOPs could work, but not the workflow I was looking to offer on an asset. But it might end up being the way I do it in the end.

In a way I wish some move that are available in SOPs would also be available for OBJ in mind, since in this case one could maybe:

- With an OBJ Merge, the artist could just like the Merge SOP bundle many objects.
- With a OBJ Group one could use something like a expandobjgroup() to retrieve a list of obj names.
- An OBJ level wrangle to control transforms instead of having to go CHOPS.

Anyways, if anyone knows a better way to group objects and retrieve info from them in a ordered way, other than naming, let me know.


Retrieve objects parameters in an ordered way. Dec. 7, 2018, 3:12 p.m.


I'm trying to use OBJ level animatable objects to drive setups in SOP level.

In XSI/ICE I would:
- Add nulls to a group.
- Get the group in ICE and access common parameters on those objects like an array from a get node where the returned data for example for “group1.Position” was an array of vectors of the positions of each null in the group.
- The group is ordered and if I change the group membership order of the nulls the array data reflects that.

I know I can get similar workflow with an Object Merge SOP, but I don't see a way to reasonably allow an artist to reorder the list of objects:
- If I use a @bundle the order is according to the object name, so this is not practical, because I don't want the user to have to rename objects either to control the initial order or for example to insert another object in bundle in the middle of existing objects (if I have c0,c1… c98, c99 and I want to have a new object after c50, I'll have to rename all from c51 onward to add 1 to their suffix.)
- If I simply add multiple objects in an Object Merge SOP is both cumbersome to do for a lot of objects and I can't change the order of them afterwards.
something like this would be handy, or if there were arrows in the entries

A OBJ level Merge node would be great since it simple allows to change the order of the inputs. Is there anything like this or some workflow I'm missing?
