<p>The four cubes are attached to each other on their edges initially. They start to fall and collide with the ground. More importantly, I want them to collide with each other during this process.</p>
<p></p>
<p>I have been struggling about what might be wrong, since they always keep going through each other, even though I already set the strength of SolidCollide super high (1000). How should I make it right?</p>
<p></p>
<p>Another question is about the hinge. I notice that even if I disable the Hinge, the objects are still somehow attached on edges due to auto-combing of the two points. Do I still need the Hinge component?</p>
<p></p>

<p>Hi Daniel,</p>
<p>Great to see your update! It works really well, especially after a bit tune of the strengths to prevent them from breaking apart. </p>
<p>I am wondering about another issue about the rigid collision of Kangaroo. Since it is a bit different question, I will start a new thread right away.</p>
<p>Thank you Daniel!</p>

<p>Hi Addin,</p>

<p>So the focus has been on form-finding and optimisation, particularly for architecture, so things like catenary forms, tensile structures and panelisation.</p>
<p>Things like rigid body collision, which are usually a major focus for typical animation focused physics engines have only come to Kangaroo more recently and are still relatively less developed.</p>
<p>I had a go at the chain example:</p>

<p>I am quite interested in the chain effect that shown in the video above. Is there a easy way to simulate this in Kangaroo? </p>
