These physics object wont fall straight down

If you are using rigid bodies, you have to understand the concept of convex hull. Convex hull means: your mesh will be simplified as if it would wrapped with plastic. So your ground plane, which shape ...

Can you bake multiple rigid body simulations in a single file?

If you think about it, what baking rigid bodies mean and what the animated checkbox does, you should be able to answer your question yourself. Baking a rigid body means: Blender creates keyframes ...

Blender Rigid Bodies stop simulating at a random frame

it's because you are disabling rigid body via keyframe at frame 728 so either move the keyframes or keyframe "dynamic" again, then delete the cache and bake again.

Can you do this level of simulation in Blender?

You can do this sort of thing- floppy overlapping objects using soft bodies with plushy,carpet, or felt textures on the objects. We need a little space between them so they don't fall too quickly. ...

Is there a way to easily add all Rigid Body objects and Constraints in a scene to the Rigid Body World?

I guess the main problem will be to get all duplicated rigid bodies selected. Perhaps you could do this by disabling all collections without rigid bodies and then pressing A in the 3D Viewport or the ...

Change the Plane's Shape setting under Collisions from Convex Hull to Mesh and your cube animation will work correctly.

why is there an invisible line on the top of the cup that is preventing the ball from falling in?

Rigid bodies have collision parameters that by default defined the collision shape as a convex hull around the shape. As your object is hollow (concave), you need to change this parameter to mesh, so ...

Why won't my rigid body obey the constraints/physics of the scene?

Blender's physics aren't real world physics, and there tends to be things that they're good at and things that they're bad at. In the case of rigid body physics, they're good at low energy collisions ...

object has no attribute pose bone

Blender 4.0 introduces Bone Collections which replaces Bone Groups. The add-on needs to be updated to account for that change. Another option is to use this add-on with an older Blender version.

Why is there a gap between the sphere (active rigid body) and the box below it (passive)?

This has happened to me a couple of times. The first thing I would check is the scale. If your objects are too big or too small, the simulation gets a bit wonky. Scale your model so your objects are ...
