I have a rigid body simulation where all the Suzanne heads are exploding outwards and going through a solid object and I can't really find out why. I am using blender version 2.8, any help would be appreciated. I want the Suzanne heads to pour out of the box into the bowl. The box is animated.

these are the Suzanne head settings

  • $\begingroup$ What did you use to make the suzanne heads explode? $\endgroup$ – Nate_Sycro27 Dec 10 '19 at 2:51
  • $\begingroup$ I did use anything, I didn't do it on purpose. They should just fall into the box but they explode instead. $\endgroup$ – Zack Dec 10 '19 at 2:58
  • $\begingroup$ May i ask you to add some more details like what you want to do, as i thought all suzsanne heads where supposed to be in the box to start with, supposed to wait for something. In that case starting them deactivated may help. But now i read they should fall in the box. So to help others help you, i suggest to add more details, and maybe even the .blend file, as that could allow easier understanding too. $\endgroup$ – Xylvier Dec 10 '19 at 3:04
  • $\begingroup$ I'm currently having problems uploading the .blend file but I will upload it as soon as I can get it to work. And to clarify, they start in the box but they should "settle" in the box before being poured into the bowl. $\endgroup$ – Zack Dec 10 '19 at 3:13
  • $\begingroup$ I am understanding it that you want the heads to act like cereal, settled into the box, then when you pour them out to be like pouring cereal out of the box. Is this right? $\endgroup$ – Jarrett Vann Dec 10 '19 at 3:47

I figured it out, the issue wasn't with the Suzanne heads but with the box they were in. It's collision was set to Convex_Hull making the box solid all the way through instead of being hollow. Therefor causing the Suzanne heads to fly outwards. Simply changing this setting to Mesh did the trick. Thanks to everyone who tried to help.
