Unigine::TileSet Class
| Header: | #include <UnigineTileset.h> |
This class is used to manage a regular tileset of the ObjectTerrainGlobal. The tileset can have an arbitrary number of tiles. Each tile is represented by the following elements:
- Data - an image with tile data.
- Mask - a single-channel image describing data weights.
NoticeIn case if a tile has no mask, all weights are considered equal to 1.
