grass_01

Warning
The scope of applications for UnigineScript is limited to implementing materials-related logic (material expressions, scriptable materials, brush materials). Do not use UnigineScript as a language for application logic, please consider C#/C++ instead, as these APIs are the preferred ones. Availability of new Engine features in UnigineScipt (beyond its scope of applications) is not guaranteed, as the current level of support assumes only fixing critical issues.

This article describes the data/samples/objects/grass_01.cpp sample.

The grass_01 sample demonstrates how to place the grass according to a mesh mask, namely:

  • Add the grass to the editor
  • Set a transformation matrix and assign a material to make the grass visible in the scene
  • Specify the required options: maximum visible and fade distances, width and height, step for cells used to render grass, density factor, etc.
  • Set the mesh-based mask to specify the areas where the grass should grow

Grass placed according to the mesh mask

Notice
In this sample, the samples/objects/meshes/grass_01.mesh planar mesh is used as the mask.
