how realistic is unity3D's physics supposed to be ?
So i've been trying to get into unity3D, to see if it's any good.
i'm trying to make a pinball machine just to test things out and see how everything works.
But i fairly quickly came to the point where i discovered that if i make a little ball with realLife size/scale (0.03) it just sinks into the underlying object..
why?
Now i read in some other q&a that is has something to do with the physics engine using float math. but shouldn't things be normal if i also rescale the cube on which the little ball is landing to the same small scale?
Am i not supposed to use real life scale ?
is unity3D just not made to use some marble sized balls ?
I seriously wanna make games with marbles.. should i just give up on unity3D or am i doing things wrong ?
You need to scale everything up. The physics engine does not do well with objects as small as you are working with.
You may want to tweak the settings in the Physics Manager:

Specifically, I suspect you need to lower the Min Penetration for Penalty setting.
Physics are fine really , i myself havent encountered your problem so can you upload a screenshot or the scene? Maybe you could switch the collision detection to continuous dynamic?
I've had problems in the past with a small ball not colliding with certain objects correctly. You may want to increase the FixedTimeStep value in your projects physics properties.
