Aurora Flex

From NWN1 Custom Content Guide

AuroraFlex is used to create dangly meshes. Dangly mesh is a very simple physics system for the vertices of an object. They can be affected by:

• part movement relative to the world (they have an inertia)
• wind dynamics, either from global wind settings or from wind events like explosions.

Dangly mesh was used in the game for objects like hair and cloth. We use vertex colours (at the bottom of the edit/editable mesh roll-out) as a value of the tensile strength of a vertex's position. The colour is normalized between 0 and 1, 0 being black and white being 1. If a vertex has a colour of white, then it will not move when subjected to the forces listed above… if it is black, it will have the full distortion value that it will be subjected to. The amount that a vertex will be moved is defined per object in the AuroraFlex modifier.

The AuroraFlex modifier has three main parameters: Sway The strength of the flex that causes it to stop. Think of it as friction. A lower value means it takes longer for it to stop. Strength The springiness of the verticies. Higher value means it will snap and bounce a lot, while a lower one means it is more lazy and smooth. Flex The distance a vert is allowed to move. You can choose to either display the displacement range based on the overall max displacement or scaled by weights. In either case, each vert will show a circular area that shows it's displacement. By using the weight slider or spinner you can apply weights to selected verts.
