Title: Leaf Color Clusters with Forest color. Fall trees.
Post by: SB3663 on September 24, 2016, 04:06:46 AM
Hello,

Currently in Colorado the trees are Mostly Green, with clusters or patches of leaves turning yellow. My question, Is there a way to use forest color to get "clustered" leaf colors. If so how could I also implement a falloff to blend the cluster?  Currently I can ad in the percent of yellow leaves but they are distributed randomly, very use full but not quite hitting the mark.

Hi,

I would suggest you to mask these "clusters" with a Noise map in the World XYZ Coordinatates Source mode. There are many ways how to apply it - like directly to the Diffuse map slot of used material, within a Composite map (as a Layer map / a Mask) and so on.

A recommendable set-up would be to use it as a Mask to blend two Forest Color (http://docs.itoosoft.com/display/FORESTPACK/Forest+Color) maps (for example one with the Tint Override feature enabled), as this way you'll have possibility to add slight additional tone variation also for each leave. Attaching a sample scene. Hope you'll find it useful.

Best regards,

This technique worked perfectly. Adjusting the contrast and the size of the noise created plenty of variations. Thanks so much!
