====== Physics Settings ======

Having trouble getting consistent Card House behavior. When I make a simple 2-D array of cards, it falls. Trying to find proper settings so that cards will sit properly until impacted.

This setting causes less jitter, and cards don't fall through the base:

  Scene -> Rigid Body World -> Steps Per Second = 120

The speed (Scene -> Rigid Body World) was at 0.5. When I changed it to 1.0, the cards fall through base.
Solver Iterations didn't have effect on card falling behavior

But the cards fall when playing animation (Alt-A).

--------------------------------

Trying different "Card" settings to determine best House of Cards settings.

^Units|Metric|
^Scene\\ Rigid Body World\\ Speed|1.0|
^Steps Per Second|120|
^Solver Iterations|50|

^Base Collision Margin|Off|
^Base Size|10x10x.5|
^Base Collision Shape|Box|
^Card Size|2.5x.05x3.5|
^Card Collision Margin|.05|
^Card Collision Shape|Box|
^Array Offset |Z=1.02|
^Card Mass|1.0|

I made a single card, used the array modifier to create 5 vertically, applied modifier, separate pieces by loose parts, Transform -> Origin to Geometry, applied physics with left panel "Add Active" - configured according to table above, then clicked all cards, click "Copy From Active".

Now need to see if this works for smaller cards. One utube author commented that Blender doesn't work as well with smaller objects.

Was able to stabilize a panel matrix by setting Scene -> Rigid Body World settings high like this:

^Speed|1.0|
^Steps Per Second|500|
^Solver Iteration|1000|

Slowing the speed to 0.2 or 0.5 worked with lower StepsPerSecond and SolverIteration values. 7/21/2016 11:14 a.m.
