You can affect the turbulence limited to a sphere , thats right in the Turbulence node, you can also channel the result noise to the maps node, and this way you can mix it with a texture map. You can use the Field / Maps node with some fractal noise texture to move the particles. Please see how the Turbulence noise is channeled in the ‘HUD / Data / Data Grid’ preset to the Replica node, and use the same process with the Field / Maps node. Aharon
