virtual FString GetDerivedDataKeyString
&40;
const FTextureBuildSettings & InBuildSettings,
int32 InMipCount,
const FIntVector3 & InMip0Dimensions
&41; const
Remarks
Gets an optional derived data key string, so that the compressor can rely upon the number of mips, size of texture, etc, when compressing the image A string that will be used with the DDC, the string should be in the format "_"
Parameters
| Name | Description |
|---|---|
| InBuildSettings | Reference to the build settings we are compressing with. |
| InMipCount | Mip count of the physical texture that will be built - 0 for virtual textures. |
| InMip0Dimensions | Mip width/height/slices of the physical texture that will be built - 0s for virtual textures. |
