xpScatter

xpScatter enables you to scatter your objects over multiple scene geometry, from splines to parametric objects all at the same time.

The topology tab will enable you to distribute your scatter on landscape slope, height, and curvature to create realistic ecosystems.

Animate your growth by using textures, X-Particles modifiers, and Mograph effectors.

Use multiple display modes for fast viewport performance. You can even restrict the scatter of objects to within the camera field of vision for optimal efficiency.
