grass_02

WarningThe 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_02.cpp sample.

The grass_02 sample demonstrates how to place the grass on the terrain according to an image mask, namely:

Load the terrain
Add the grass to the editor and make it a child node of the terrain
Notice
It is also required to enable intersection with parent objects to make the grass grow upon the terrain.
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 image mask according to which the grass is placed

Grass placed upon the terrain according to the image mask

NoticeIn this sample, the samples/common/terrains/terrain_grass.png mask is used.
