Use Multiply Vector by Matrix to multiply sphere.PointPosition by sphere.kine.global first. Then calculate the dot product.
When you get attributes like Sphere.PointPosition by explicit reference (i.e. not reading at locations), you get the raw values, which are expressed relative to the object centre. Multiplying by the global transform converts to them to the global reference frame. gray From: [email protected] [mailto:[email protected]] On Behalf Of Simon Van de Lagemaat Sent: Thursday, April 26, 2012 05:27 PM To: [email protected] Subject: Evaluating ice weight map gen per frame I'm generating a weight map on a mesh using a simple dot product of a null and the surface points on the sphere. When I animate the sphere the weight map generation is ignoring the transforms and acting as if the mesh is in a rest state. How can I get the weight map tree to eval the mesh and its transforms on every frame? I created a simulated ice tree but no luck. Cheers
