image of connect4 piece not going in connect4 boardI'm making a connect4 animation, I've made all the pieces for it, and I'm using rigid body physics to simulate the piece dropping into the board, but it stops when it hits the top of the board, as shown in the picture. I've double checked the sizes to make sure the piece is smaller than the hole, I've also tried changing the collision margin like in this question, but i'm unsure where to go from there

for reference, the piece is an active-type rigid body while the board is a passive-type rigid body

    $\begingroup$ I'd suggest you don't actually use the model of the connect four board as the actual collision. Instead make the dividers in between rows simple rectangles, same with the front and back of the board. This will help it be a lot more predictable. $\endgroup$ Mar 15, 2021 at 22:36

Most likely you have your collision set to the default of 'Convex Hull' in the Rigid Body settings. Try changing to 'Mesh'.
