Fracture + Rigid body + Collider body = failure??..
Okay, so I’m trying to create a crash scene. I created the ship, I’ve disconnected the polygon faces (so it shatters), I have placed this in a Fracture with the Object Mode set to Explode Segments (so each piece is individually falling). I then put a Rigid body tag on the Fracture. I tested the scene out so it would fall on a generated landscape with a Collider body tag. It worked really well.
BUT the real problem is when I put it on to a generated landscape I ‘current state to objected’ so I could edit it (sculpt, thats not the problem though as when I take the tag off it doesn’t change anything). When this edited landscape has a Collider body tag (just the basic one without any setting changes), the fracture debris float up, WITHOUT coming into contact with the landscape. It doesn’t seem to matter where they are in relation to each other, if that landscape has a Collider body tag, the fractured objects float up.
I’m not sure what is wrong with my landscape, and I really need both objects.. let me know if you need screen shots or the file, and thanks in advance!

what is Collision/Shape set to in the collider body tag?
-
Collider body tag is just the automatic settings Dynamic: Off , Trigger: Immediately , Transition Time: 60F. I found that if I put the landscape which has the collision tag (that makes the ship float) in a cloner that the ship doesn’t float away, but it then goes through the landscape (tried putting the collision tag on the cloner and had the same effect).

those are the settings in the collider tag’s Dynamic tab but what are the settings in the Collision tab (just to the right)? The Shape setting there sounds like it’s on Automatic but it should probably be Static Mesh – or are you working with a much older version of C4D?

Hope the image uploads, thats what its on. I’m also using Cinema 4D Studio 15. But the bounce (50%) shouldn’t come into it if it doesn’t come into contact?
Settings for collision
Inherit Tag: None
Individual elements: Off
Self Collisions (tick)
Shape: Automatic
Size Increment: 0cm
Use (no tick)
Keep Soft Body Shape (tick)
Bounce: 50%
Friction: 30%
Collision Noise: 0.5% -
yes, Shape is set to Automatic – try changing it to Static Mesh

Thank you, that completely fixed it! you sir are a genius
