Erosion Studio

Sculpting Workflow

While Gaea focuses on chaining nodes to generate and process terrains, Erosion Studio allows you to sculpt erosion by adding "hits" with a mouse on an existing terrain. However, it is still a procedural process - each hit is recorded and if the underlying terrain is modified, every single hit is reapplied. This gives you deeply art directable erosion in a non-destructive workflow.

Erosion Studio provides several Sculpting Tools that let you erode, add sediments, and create surface effects. As everything in Erosion Studio is powered by erosion, gravity and slope play an important role. See Basic Sculpting to become familiar with Erosion Studio's distinct tooling.

What makes Erosion Studio quite unique is that lets you work with very high resolution terrains (up to 128k [131,072 x 131,072], given adequate RAM) in 1:1 resolution in realtime.

Preparing a Terrain

Erosion Studio requires an existing terrain. You can use any terrain as long as it is a .r32 (Binary array of 32-bit floats) format heightfield. Gaea can export any heightfield to .r32. If your original source is from elsewhere, you can load that file in Gaea using the File node and export it to .r32, then load it in Erosion Studio.
