I have modelled a tray into which i have a thousand small coloured bricks being dropped in.
The bricks are being directed into the tray using an invisible funnel - because my cloner object is using an image object to control the colours of the clones and is too wide to drop in cleanly.
I have a Collider body tag on both the tray and the funnel, and i have a rigid dynamics tag on the cloner object.
When i run the simulation the bricks fall in, but then they float above the tray base and they stay roughly a centimetre from the tray walls. It also appears that the floating plane is not perfectly flat but tilting to one side and some of the bricks are breaking through the tray base slightly.
please can you suggest areas that might be the issue?
i cannot see any settings that would suggest a "force field" around the boundaries. I have also set the Scene Scale (in Project settings/Simulation to 6.5mm because that is the size of each brick, and i was told to match those to help stop the bricks vibrating constantly.
i tried to add a project file but i cannot make it smaller than 3.2mb and the upload says theres a limit of 2mb files.
