Made the cloner object editable, and added Mograph rigid body tags to each cube. Added a floor, mograph rigid body tag, as well.
I intended to test the dynamics engine, to see how the cubes would react, but nothing happened when I added the tags to the cloned objects, and moved along the timeline. I tried quitting and re-opening 4d, restarting the computer, changing my scene..etc. No go. Everything else seems to work fine, no issues.
Am I missing a step, I am kinda green in 4D? But online tutorials (r11.5) say it should work.
I never had 11.5 but I believe you had to have dynamics happen inside a mograph cloner or a fracture object. I don't know if that's true for colliders as well. Since you made your cloner editable it isn't a cloner anymore so that should break it. Others will know for sure.
