Forms, roofs and cracks support basic deformable objects.
These should be placed between two rails, Rail1 and Rail2 and each must consist of up-to 8 verticies, which must strictly follow one of the two following clockwise windings:
TopLeft, BottomLeft, BottomRight, TopRight
BottomRight, TopRight, TopLeft, BottomLeft
BottomRight, TopRight, TopLeft, BottomLeft
In both cases, top refers to the furthest distance in the Z-axis, and left refers to the furthest distance in the X-axis.
These deform in the following manner:
The distance between TopLeft and TopRight will be deformed relative to the distance between Rail1 and Rail2 at the far block boundary in the positive direction of construction.
The distance between BottomLeft and BottomRight will be deformed relative to the distance between Rail and Rail2 at the near block boundary in the positive direction of construction. go
