Variables Detail

MaxTextureSize Source code

var int MaxTextureSize;

Optional max texture size clamp for the composite texture. A value of 0 is ignored and defaults to deriving the texture size using texture LOD bias settings from the source textures

SourceRegions Source code

var array<SourceTexture2DRegion> SourceRegions;

list of source textures and UV regions for compositing

Structures Detail

SourceTexture2DRegion Source code

struct SourceTexture2DRegion
{

var int OffsetX;
var int OffsetY;
var int SizeX;
var int SizeY;
var Texture2D Texture2D;

};

Defines a source texture and UV region in that texture

Functions Detail

ResetSourceRegions Source code

native final function ResetSourceRegions ( )

Utils to reset all source region info.

SourceTexturesFullyStreamedIn Source code

native final function bool SourceTexturesFullyStreamedIn ( )

Utility that checks to see if all Texture2Ds specified in the SourceRegions array are fully streamed in.

UpdateCompositeTexture Source code

native final function UpdateCompositeTexture ( int NumMipsToGenerate )

Regenerates this composite texture using the list of source texture regions. The existing mips are reallocated and the RHI resource for the texture is updated
@param NumMipsToGenerate - number of mips to generate. if 0 then all mips are created
