    Cool I need relevant suggestion

    Yes Mr .Vik.

    If I have to realistically break a glass ball of radius 10 cm and that ball is also less than one K.G then what settings do I needs to do .I have checked that the formula Density = Mass/Volume will work best if we work in actual unit scale.

    If I take the same ball and use space scale as 1 it takes 10 seconds to hit the base plane.

    If I take the same ball with space scale to .1 it takes almost 2 seconds to hit plane.

    If I take same ball with .01 space scale it just instantly drops in less then a second so why should not I need to have a space scale of .01 if I wish to do it .

    And lets leave everything just for the sake of knowledge or say trouble shooting or research i needs to know each and every method and possibility.

    Since I am putting a serious study I needs to know Sir with all due respect to you the relevant answer.

    thanks vik in advance looking to hear from you.

    Well friend I have come with an approach to you.To match the unit system of scene you can increase the gravity.

    The gravity mentioned here is 9.8m/sec 2 ok try it at 98 and see some changes.That means yours every one cm represent 10 meters of dmm physics.

    I dont know its a just a quick change i was doing since working in .01 scale is not turning a good option to me .

    pls ask some other experience fellas also.

I added a Youngs damp of 1500 to the gumballs and this improved their movement; but I still have a few inter-penetrations, floaters and a couple of odd gumball pops to fix.

    Simulation time : A little less than an hour for 200 frames
    Substeps : 16 (Could this be higher?)

    Materials used:
    Gumballs - ub_rubber (Added Youngs damp of 1500, zero toughness and no plastic deformation)
    Glass shell - Weak_crystal
    Lid - ub_diamond (lowered density to 1000)

    Hello Mr.Vik,

    Do u reply me for the question of using Space-scale .01 in Dmm simulations?

    The way out I found this to increase the gravity to 980 or 98 by doing this i can increase the falling speed of tets, at least tell me this new way out is good or not?

    Pls let me know I need to work for my research project on DMM

    You can always speed up playback or slow it down for dramatic effect. You can change the frame rate in Maya->Preferences->Settings->Time.
