The xpVertexMap Maker has four different modes to manipulate the vertex weight; Vertex Speed, Texture, X-Particles/Object Vertices and xpExplosiaFX.
Vertex Speed, weight is calculated by how fast the object vertices are moving. You can use the weighted object as a particle emitter, access the vertex weight information to drive a scale modifier dynamically, and particles can be scaled up when their weight is full and down when their weight is 0 - excellent for motion graphic effects.
Texture, uses the greyscale values of any texture to drive the vertex weight.
X-Particles/Object Vertices, drag in your X-Particles emitter and wherever your particles make contact with the map they will paint weight.
ExplosiaFX, use with our new xpExplosiaFX object to create custom vertex maps from fire and smoke simulations.
Our new xpVertexMap Maker enables you to create fully procedural real time Vertex Maps inside of X-Particles 4.
