I’m not really sure how to fix this. I think it wants me to put the distance between both attachments here:
in the ‘length’ property, however I’m not sure how to get this information.
Can anyone help solve this constraint error? Thanks!
Your attachments are 2.401 studs away from each other in world space whereas your rodconstraint’s length property is 3, you should either make your attachments closer, or change the length property to 2.401
Guessing you have nothing providing upwards force on the body. Rod constraints just ensure a distance between the two attachments is kept, they can rotate in any way similar to a ball socket constraint.
