adding a particle system to a UV map


i’m modeling the transport of a chemical component. Long story short, I’ve a plane that I’ve uv-textured with my chemical component, let’s say a green circle, the rest of the picture being transparent. What I want to do is add a particle system to this green circle to simulate the propagation of my chemical.

I’ve seen on several websites that it s possible to do it, but haven’t found a way to do so… anyone can help on this ?

many thanks,


When you add a particle system you will then have the option in the Texture panel to add a particle texture. In the Texture / Influence setting you can then set it to Density.

See the attached example blend
