Terrain Nodes is designed to be a flexible solution for creating realistic terrains right inside Blender. What sets it apart is the use of your NVIDIA GPU to quickly perform erosion and other simulations.
Generate terrains using provided noise nodes, import from ANT Landscape add-on, import objects generated using geometry nodes (2D grid only), import images or use provided texture bake tool to convert procedural textures into image height maps.
- Use flexible node UI to design unique erosion filters.
- Very fast GPU powered erosion on massive scales - Resolution of terrain erosion will depend on GPU RAM. From experiments 2GBs was enough for 4096 x 4096 resolution, but your results may very. On my GeForce GTX 1070 8GB GPU it only takes 3-4 seconds to erode 512x512 terrain, with every erosion setting enabled.
- Cache system - calculated nodes are cached and reused unless settings change.
- See Erosion as it happens as a 3D mesh and / or Image previews.
- Hydro Erosion - 2D water simulation runs down slopes and picks up sediment, slowly (or quickly) eroding the terrain. Sediment is deposited in lower areas or where speed of water flow is reduced.
- Thermal and Sediment Slope Erosion - Thermal erosion erodes steep edges, smoothing out the landscape. Converting terrain and rock to sediment. The sediment slope erosion moves sediment down until a stable slope is reached.
And many other features, see the links below for complete list!
Terrain Nodes is available as a paid and free version (free has limited simulation at 512x512 pixels).
