That's an issues of MSPhysics and it will be fixed in version 1.0.0. I already made some descent improvements to world scale. So, once it's released it should be working all well.

Thank you Anton.

I exported the SP animation to KerkyThea and rendered directly. Kerkythea saved everyframe to my desktop within a folder (which is starting with "Anim_*") in jpg format. Then I used the free MakeAVI software to merge all the jpg's as a movie. I am not happy with the quality and the flickering of the shadows. I don't know how to fine tune KerkyThea.
