False when it changed nothing, in which case nothing was written and nothing was recorded for undo.                                                                                                                                                                                                                                                                                                                      |
| [changedCount](/engine/7000.0/script-reference/unityeditor/terraintools/terraineditresult/changedcount.md) | The number of samples whose stored height changed, or of texels where a layer weight changed by at least half of the alphamap's 8-bit storage step.                                                                                                                                                                                                                                                                                                      |
| [rect](/engine/7000.0/script-reference/unityeditor/terraintools/terraineditresult/rect.md)                 | The rectangle that the edit can change: heightmap samples for [TerrainEditUtility.SculptHeights](/engine/7000.0/script-reference/unityeditor/terraintools/terraineditutility/sculptheights.md), alphamap texels for [TerrainEditUtility.PaintLayers](/engine/7000.0/script-reference/unityeditor/terraintools/terraineditutility/paintlayers.md). It covers the region, widened to the cells it crosses, and the blend band. Nothing outside it changes. |
