Snow filter adds falling snow to a picture or movie. The main controls (first 3 sliders) allow you to adjust how fast the snowflakes are falling, make the snow come down at an angle (wind simulation) and randomize snowflake direction. The next two sliders control the snowflake density of the near and far showflakes. Parameters: Speed Controls how fast the snowflakes are falling. Wind Controls how much the snowflakes drift to left or right side. Chaos Randomizes snowflake direction. Snowflakes Near plane snow density. Snow Far plane snow density. Free* Free effects are fully functional even in AnyFX DEMO. See also other simulations: Rain - add falling rain to your clip.
