As shown in the following graphic, I am trying to use nParticles in order to simulate a dissolving painting
I've been able to figure out out to make the particles acquire the color of point on the painting where they emerge from, however the particles are clumping on the floor at the base of the painting. The particles spread nicely down because the particle goal is the surface from which they are emitted. However I would like the particles to spread about the base of the painting once they reach the floor.
Also, I would like to merge or convert the particles into a smooth surface for rendering. This smooth surface should retain the colors of the various particles.
I've uploaded the scene shown in the above screenshot, including the image that I'm trying to melt, as a zip file to:
