Well judging by his uploaded scenes he is using Algodoo, and when you said "thymeless" i assumed no thyme at all as most people would perceive it
"with only one change on scripting.(InertiaMultiplier for pistons LOL)"
And this is a lie as there are 2 changes in scripting which when you said this also made me think you used no thyme further supporting what i said above
Also you appeared to have updated the scene since i first downloaded it and now the new one works and the old one is still a piece of crap
