Help Mesh intersection through cloth and not getting perfect simulation on character cloth

[Himanshu]

Nope, that's not doable in realtime. You might get better results by using a smaller timestep (or increasing the amount of solver substeps), but this is way too ambitious a goal for realtime character clothing.

Thanks a lot but i want to ask one more thing that, is it possible to access skin radius, skin backstop and skin backstop radius on runtime?
I am able to increase the size of the cloth using distance constraints, but unable to make them smaller... 
If is there anything to make it right please suggest me i will try to figure out something from them 

Thanks a lot,
