Let’s check out a session by SideFX and Alex Dracott about generating HeightField terrain textures in Houdini.
This session will be focused on generating HeightField terrain textures within Houdini. Specifically it will cover the basic pipeline of taking mask and height information from your Heightfield terrain, bringing it into a COP image network to generate textures and splat maps, and finally bringing it back onto your terrain or saving for later use.
Make sure to check out the Go Procedural channel on Vimeo for more videos on Houdini.
