In this special seasonal instalment of our regular tips and tricks episodes, we’re going to look at a rather unusual use for Forest Pack — adding snow to trees. It might not be the obvious choice of plugin for this task — after all snow normally forms a continuous blanket-like mesh, and Forest Pack scatters hundreds of thousands of individual objects — but when coupled with a metaballs plugin, Forest Pack can be used to add a covering of snow to high polygon objects really quickly.
In this tutorial we’ll examine two techniques for adding realistic snow to a tree, starting with covering only the branches that are visible to the sky and not obstructed by one another. We’ll then build upon these foundations to add a denser coating of snow by covering all the tree’s upwards facing polygons. Finally we’ll use our new snow covered tree assets to populate the small environment shown above.
