I have recentry made a really nice engine that is fully working without any problems, but the problem was that it is very basic. Here is what it looks like:
Then I tried to make it more realistic:
But when I used the same technique with the constraints I have met a problem: models don’t have constraint grid. So I made invisible cylinders (AttachPoint) which can’t collide anything and I welded them to the models, adding no collision constraints between the rod and every other model it collides and added hinges between the cylinder head’s pin AttachPoint - rod’s upper hinge AttachPoint and rod’s lower hinge AttachPoint - crankshaft’s AttachPoint which made a really nice effect:
When I tested it I saw that it works just fine and it’s time for the cylinder head’s upper AttachPoint to be connected to the anchored AttachPoint on the floor via a cylindrical constraint just as how i did on the other engines:
But then something unexpected happend:
I put the motor to inf torque but nothing… it was still glitched. I also double checked the cylindrical if it has any limitations or differences comared to the other cylindrical… Idk what else can I do for now so please help me!
