UE4中TextureCoordinate
官方文档中
The TextureCoordinate expression outputs UV texture coordinates in the form of a two-channel vector value allowing materials to use different UV channels, specify tiling, and otherwise operate on the UVs of a mesh.
| Item | Description |
|---|---|
| Properties | |
| Coordinate Index | Specifies the UV channel to use.指定要使用的紫外线通道。 |
| UTiling | Specifies the amount of tiling in the U direction.指定U方向的平铺量。 |
| VTiling | Specifies the amount of tiling in the V direction.指定V方向的平铺量。 |
| Un Mirror U | If true, undo any mirroring in the U direction.如果是true，撤消U方向的任何镜像。 |
| Un Mirror V | If true, undo any mirroring in the V direction.如果是true，撤消在V方向的任何镜像。 |
简单的说就是 u是几 那么在u方向就重复几次，v是几就在v方向重复几次
