To set up initial weighting for a Muscle Smart Collide node

1. Create and connect the node to a deformer as described earlier. (See Set up Muscle Smart Collision and Connect selected Muscle Smart Collide nodes.)
2. If you have not already done so, on the cMuscleSystem node for the object you are deforming, set the smartCollision attribute to “on”. This enables Smart Collision on the deformer.
3. In the Paint Weights window, set weights for the Smart Region A and Smart Region B weights for the connected node.

   Typically, you want to set weights to 100% value for each region. Areas “before” the plane would be “A”, and after would be “B”. For example, if the collide node is parented to an elbow, the upper arm points would be “A” and the lower arm “B”. These regions help determine what points are allowed to be deformed and collided by each A or B attribute.

   If you have a span of points that is shared, set the weights to 0.5 instead of 1.0. This allows the points to be affected by both attributes.

   

4. Weight the other Smart Collide weights and set the values you require on the node.
