Syntax
class FDynamicMeshUVPacker
Remarks
FDynamicMeshUVPacker implements various strategies for packing UV islands in a UV Overlay. The island topology and UV unwraps must already be created, this class simply scales/rotates/translates the islands to fit.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
bool | bAllowFlips | If true, islands can be flipped in addition to rotate/translate/scale |
 |
bool | bScaleIslandsByWorldSpaceTexelRatio | Attempt to rescale islands to match texel-to-world-space ratio across islands, based on ratio of World- and UV-space edge lengths |
 |
float | GutterSize | Thickness of gutter/border in pixel dimensions. Not supported by all packing methods |
 |
int32 | TextureResolution | Resolution of the target texture. This is used to convert pixel gutter/border thickness to UV space |
 |
TUniquePtr< TArray< int32 > > | TidsToRepack | The explicit triangle ids to repack, repack all triangles if null |
 |
FDynamicMeshUVOverlay * | UVOverlay | The UV Overlay we will be repacking |

 |
bool | StackPack () |
Uniformly scale all UV islands so that the largest fits in positive-unit-square, and translate each islands separately so that it's bbox-min is at the origin. |
 |
bool | StandardPack () |
Standard UnrealEngine UV layout, similar to that used for Lightmap UVs. |
