what is the general rule for mesh density vs jbeam density?

If a jbeam is too dense (many nodes and beams) what could be potential problems? and if a jbeam is not dense enough (few nodes and beams) what could be potential problems?

Also should the density of the mesh have any bearing on the density of the jbeam?

For example take a cube with 10 squares on each side (faces) would a jbeam with 2 squares on each side be good. Now a cube mesh with 100 faces of each side (faces), would a jbeam with 20 squares on each side be good?

I'm trying to gauge density of mesh vs density of jbeam.

 

Well... not 100% sure on the mesh, but as far as the JBeam goes, the more nodes and beams you have, the more realistic you can make your physics structure and in turn, the more realistic it will deform. However, if you go too far, you will start to overload the computer trying to run it. This will have obvious consequences... Lag being the biggest one.

If you go to low with the nodes and beams, you will start getting unrealistic deformation, as there is not enough support structure to make it deform realistically. Also, when the mesh starts to deform on top of that, the lower the JBeam density, the more likely you will get jagged artifacts on your mesh when deforming.

I hope someone else can answer the mesh side of this question and then give you a rough estimate as to a good ratio better than I can.

 

Ok thanks! I know with the mesh side of it the more complex the more you can get jagged edges, i'm starting to get that with the sides of mty bus since the stripes are acutal geomerty and its pretty dense, im looking into making them normal mapped.
