Volumetric Falling Snow

Volumetric Falling Snow These operations were carried out on the PC Windows version of Bryce 3D Rev 3.1
The beauty of using a volumetric material for falling snow is that the nearer an object is to the viewer the fewer the number of snowflakes are shown before the object.
	Create your scene as normal like the top one opposite. Use a grey sky to best show up the falling snow which will be added later. The lower image shows the scene with the falling snow added. For a larger view click here: Full Size Picture. Click your Browser back button to return to this tutorial.
	Create a sphere at World Centre and click on the A button to bring up the Attributes dialogue box.
	In the Attributes dialogue set the X, Y and Z Size to about 200.
	Apply the Flat White material from the Simple & Fast group to your large sphere.
	Now click on the M button to enter the Material Editor. Change the mode to Volume and place value buttons in Column A against Diffusion, Ambience and Base Density. A random material will appear. Change this to the Blue Spots material in the Basic group.
	Now set Base Density and Edge Softness to 100. Set Fuzzy Factor to 300. Set Quality/Speed to 50. Set the Scale of Blue Spots to 100%
	Deselect Cast Shadows and select Additive. Return to the Scene Editor and render.
You can vary the scale to produce larger or smaller snowflakes and altering the size of the sphere has some effect. Happy Christmas to you all.
