Rigid bodies disappear once simulation is cached

[Anonymous]

Hi,

I have a simulation that runs just fine when caching is off, but as soon as you turn on caching, the rigid objects disappear once the collisions start happening. If you scrub through the timeline, the rigid bodies appear in some frames then disappear in others. Frames where the rigid objects are visible render as you'd expect, but if I try to render a frame in which the rigid bodies have disappeared, I get this warning:

// Warning: bowlingBallShape has an invalid bounding box and will not be rendered.

What's going on?

Ok, it seems the problem was the Playback speed setting under Window > Settings/Preferences > Preferences > Settings > Time Slider.

If it's set to "Real Time" when you do your initial runup, then rigid objects will disappear during the cached playback, and the scrub-through will have a lot of stuttering and flickering.

If it's set to "Play every frame", the cached playback will work just fine, and the scrubbing will be smooth.
