3ds Max Landscape Plugin -

It handles practically limitless geometry through advanced instancing. It features built-in parametric distribution maps, clusters, and boundary controls.

Before diving into specific tools, it is important to understand the limitations of a vanilla 3ds Max workflow regarding landscapes: 3ds max landscape plugin

Gaea is a standalone, node-based application dedicated to terrain generation, offering unparalleled control over simulations like erosion, hydrology, and tectonic movement. You build your terrain in Gaea's graph, export it as a high-resolution mesh and texture maps, and then import it into 3ds Max for final layout, scattering, and rendering. This approach combines the best of both worlds: Gaea's procedural power with 3ds Max's scattering and rendering capabilities. node-based application dedicated to terrain generation
