Learn how to create a flowmap using the new Flow Map tools in Houdini. You will see how control the flowmap velocities by using terrain geometry, a curve, and also how to manually comb it if you wish for more specific control. Then export the mesh geo, bake out the flowmap, and assemble your riverbed in Unreal Engine.

Andreas has spent a third of his life as a VFX artist in the games industry working on games of all shapes and sizes. From gritty explosions in Battlefield 1 to whacky powerups in Disney Universe He recently realized that there is a despicable lack of educational material for realtime vfx so he decided to try and do something about it. In both his work and tutorials he strives to live by KISS (Keep It Simple, Stupid). Finding simple solutions to hard problems has become an addiction and it's the reason he's neck deep in Houdini. He's currently freelancing for some of the biggest names in both games and VR.
