Hi, im trying to connect these series of cubes together as shown here :
The orange cube is fixed in its position, and all the other cubes (with gravity) are connected in a series of fixed joints. My problem is that the fixed joint don't really fix the objects in their positions, but rather "dangle" around like a spring, as shown :
Sorry for the pictures, coudn't figure out how to post them there.
Your best option what i use a lot for certain things is either turn the solver iteration count up in physics to make joints more solid, however this will add performance drain as it effecting every joint in game.
Or what i normally use is a configurable joint lock all and then at the bottom u will find projection turn this on for rotation and position and underneath set the limits to 0, u may also have to turn solver iteration up a little depending on your setting.
Remember setting this can make objects react differently, for example i made a bike game and the back wheel had to have a little room on the projection in order for the bike to have the right feel when applying forces.

Add the objects as children. This will make them "rock solid" as they will not bend, rather rotate the entire object if it gets too heavy. In this scenario you shouldn't keep the rigidbody on the child objects.
