Remarks
Generate mipmaps for height and tangent data.
Parameters
| Name | Description |
|---|---|
| HeightmapTextureMipData | array of pointers to the locked mip data. This should only include the mips that are generated directly from this component's data ie where each subsection has at least 2 vertices. |
| ComponentX1 | region of texture to update in component space, MAX_int32 meant end of X component in ALandscape::Import() |
| ComponentY1 | region of texture to update in component space, MAX_int32 meant end of Y component in ALandscape::Import() |
| ComponentX2 | (optional) - region of texture to update in component space |
| ComponentY2 | (optional) - region of texture to update in component space |
| TextureDataInfo | FLandscapeTextureDataInfo pointer, to notify of the mip data region updated. |
