| * **Sphere start**: The positions are generated using an angle interval and the min and max value for the radius. You can think of it like this; an arrow start pointing up. This arrow is then rotated around the X axis (red) using a value between min and max. After that the arrow is rotated by the y axis (blue). The arrow will now be pointing in a specific direction and in this direction a position is created at a distance from center according to a number generated from min/max radius. | * **Sphere start**: The positions are generated using an angle interval and the min and max value for the radius.

| * **Number of Files**:The number of material files used. Normally this should just be one, but in some cases an animation needed is spread out over several material files. When using several material files these must be name “[name]01.mat”, “[name]02.mat”, etc. Also the file text must be just “[name]”. So if the files are called “test01.mat”, “test02.mat”, etc it must say “test” in the file field. | * **Number of Files**:The number of material files used.

| - | * **Sub Division**: This is used in order to animate individual particles (when using several files, the material for all particles are changed at the same time). It can also be used for more variety among particles. The sub divisoion is set up by specifying how the texture is to be split and then setting how the particles will be assigned to a sub division. The splitting is like this: | + | * **Sub Division**: This is used in order to animate individual particles (when using several files, the material for all particles are changed at the same time).
