Here is a very simple demonstation of using the fh dist setting. Remember:
Do FH must be enabled on the actor (in this case the cube). The cubes physics setting is DYNAMIC.
The ground is set to STATIC. Under the materials for the ground, set DYN to on, play with the various physics settings to reduce/ eliminate the springyness. Dampening will eliminate it.
W moves right and S goes left.
This is my limit at the moment, still learning. I'm finding the transtion to 2.55/ 2.56 very confusing so this is from 2.49.
