1.9.7 + 1.9.5 inflexible hinge behaviour
Posted: Tue Jun 21, 2011 11:34 pm
I know some descriptions of bugs are very similar to that but i think this problem i have should be explained more detailed.
It is nearly impossible to get a perfect cirlce - car rolling slowly.
you hinge two cirles on a box ,put an engine on it and push it -
it stops moving instantly. The masses are influencing the hinges , they are blocking what many people should have recognized already.
you can change any value like legacy mode , hingeconstant from NaN to any int value or +inf , change the mass of the geometries is the only acceptable solve . But this influences every other behaviour to much .
if you have a engine for such a simple car for example , it cant get through the resistance of the hinge in lower speeds .that causes other problems : if you make the car heavier , the engine gets to weak .
i think it has to do with the new solver - which is great - there is no question.
but there has to be any mode that allows to have the old 1.8.5 behaviour back .
looks like legacy mode and hingeconstant are planned for that , but it does not work well.
could be that you disagree , but i definitely find it annoying.
still there in the new 1.9.7
attached a little example scene
