Parameters

heightmapPC PaintContext describing the heightmap from which to build the preview mesh.
previewTexture Specifies Whether to build the mesh using the source or destination render texture in heightmapPC.

brushXform Describes the position and orientation of the brush.

Description

Draws a Terrain brush preview mesh from a heightmap PaintContext using the provided procedural material.

The heightmapPC is used to build the mesh. To ensure that the preview is rendered on the mesh, the heightmapPC must contain an area around the brush. To facilitate proper transformation of brush UV space, this method sets up the brush transforms in the material. Important: The material provided must support procedural mesh generation in the vertex shader using the shader functions provided in TerrainPreview.cginc. A default implementation of the material is provided by GetDefaultBrushPreviewMaterial().
