I have a scenario where the debugger shows the physics working perfectly - a board hanging from a rope, and swinging on a spherical joint. But in the application, the board is static! The rope is swinging, but the board sits there like it's not attached to the rope, but screwed to the wall.

Can anyone think of a legitimate scenario where this would happen? I haven't deleted and recreated the object, so it's not that it's become detached by doing this.

I've highlighted the board in the main scene and debugger with an orange highlight (remember the debugger is mirror image!).

Not too sure about you're problem, but I was testing how many objects dp could take without lagging/crashing, and when i spawn somewhere near 1k+ objects sometimes you get objects that aren't effected by physics, and if you make tonnes to around the 4k range, they strangely get suspended in mid air, it looks similar to what you're experiencing however I never checked what they looked like in the debugger.

Hallowed are the ori.

In this scene, I only have about 150 objects max at any time. I also found that the second time it runs (after deleting and remaking the scene in between), it works!!! That would suggest my logic is OK, but maybe something gets triggered at the wrong time to force the link into the simulation.

I have made some progress, but it's still a worry. If I change the order in which the objects are loaded, it works. And the objects I have swapped the order with are also working fine too. I wonder if there is a bug with specific body types that causes this. The objects I have swapped it with are convex static objects.

This is very odd. I'm guessing you are using the async method of updating and this may be somehow causing the problem. Can you either send me your program to test or provide a small program that highlights the problem.

This is reported here also, in relation to convex bodies.
