PhoenixFD Particle Texture
The PhoenixFD Particle Texture is a procedural texture calculated over one or more particle systems by blending bell-shaped sub maps connected to each particle.
Source particle system (MXS: sources) -
this list contains the particle system used as a source for the texture.
Blend alpha (MXS: blend_alpha) - when checked the alpha of the sampled sub maps is blended, otherwise it is set to 1.
Particle scale affects the radius (MXS: radscale) - when checked the radius of the bell curve is multiplied by the scale of each particle before use. Alternatively the scale affects only the sampling of the sub maps.
Blending method (MXS: blending) -
Map (MXS: map, map_time) - the map connected to the particles. The contribution of each particle is the color from the map multiplied by a bell curve. If no map is specified a white color is used.
Radius (MXS: radius, radius_time) - the radius of the bell curve.
Amplitude (MXS:amplitude, amplitude_time ) - the amplitude of the bell curve.
Shift mode (MXS: shift, shift_mode, shift_time) - Checking this option changes the calculation algorithm. The particles do not contribute to the result color, instead they contribute to the coordinates of the sampling. The texture just returns the color of the sub map, in a point calculated by shifting the sampling point with an offset determined by the particles. This mode has no effect if no sub map is specified.
