In this video I show how you take a bitmap which is mapped to a mesh created in Blender, and create a particle cloud which matches to colors in the bitmap. I show how to use the Point Cache Bake tool to create a point cache map. I then use the map to create the particle colors and place these onto the mesh so that the colors match what the mesh’s colors are. I show how you can explode these out from the mesh, or collapse them onto the mesh for a cool effect.
