RBD emission of objects with constraints

[Pavel K]

I want to drop a bunch of objects on the floor using POPsource and Bullet solver. These objects have to be constrained to each other with unbreakable glue.

I read this thread which has a lot of great tricks but it doesn't work with my simple setup.

Maybe I need to provide a little bit of clarification.

I have three cubes on the left and constrain them together with glue = -1;

I want them to fall as one unbreakable piece and not disintegrate (right image).

all I did is this, an assemble node that doesn't treat each cube as a separate objects, your create name Attrib treats 3 cubes as separate while if you disable it the 3 are seen as one. Haven't integrity checked all your other logic...too complicated, couldn't be bothered.

here's an EXTREMELY simple file to see the effect. You don't need to be distracted by a billion other settings.

Currently the 3 boxes are treated as 1, no need for glue or anything overly complicated. Enable Create Name Attribute in Assemble and the 3 boxes will be treated as separate entities.

Thank you! For some reason I completely forgot about name attribute in assemble node. Lol, Houdini will do it to you.
