Texture – Description

– Force in the three directions is color coded (like the color of the coordinate axes in the 3D View).
– Red is coding for the X axis.
– Green is coding for the Y axis.
– Blue is coding for the Z axis.

– A value of 0.5 means no force, a value larger than 0.5 acceleration in negative axis direction (like -Z), a value smaller than 0.5 acceleration in positive axis direction (like +Z).
