Texture Properties
Document Summary: Explains the meaning of the various texture properties.
Document Changelog: Created by Daniel Wright.
Settings
AddressX/Y
Addressing mode of the texture. Either wrapping (TA_Wrap), clamping
(TA_Clamp) or mirroring (TA_Mirror).
SRGB
Whether the texture should be gamma (un)corrected or not. Regular diffuse
textures and basically anything you author for display
as color values should have this set to TRUE.
It is usually disabled for cases where the texture color values
have a specific meaning and you rely on those values to be that way as
they were set e.g. via code. Normal maps should have this set to FALSE as
their color values are to be interpreted as a direction and thus should
not be gamma corrected.
UnpackMin/ UnpackMax
The range the texture gets "unpacked" to. The default is 0..1 which
means black corresponds to 0 and white to 1. You can set the max to a
higher value if you want overbrightening via the texture. Normal maps
require the range to be -1 .. 1 and this is set automatically if you
choose the proper compression setting.
CompressionNoAlpha
Whether the alpha channel can be discarded. You want to enable this in
case your alpha channel contains data you don't care about as it allows
the texture to consume only half the memory required otherwise.
CompressionFullDynamicRange
If enabled, RGBE textures will not be range limit but will use much more
memory to store.
DeferCompression
Whether to defer compression till save time to allow faster iteration
times when importing/ tweaking textures.
NeverStream
The texture will never be streamed if set. Temporary workaround for
engine limitations.
CompressionSettings
TC_Default
Regular texture, diffuse, ...
TC_Normalmap
Normal map
TC_NormalmapAlpha
Normal map though the alpha channel contains data that you want to use.
TC_Displacementmap
Terrain displacement map
TC_Grayscale
Grayscale texture
TC_HighDynamicRange
High dynamic range texture, needs to be imported as RGBE via .float
importer.
Filter
The texture filtering mode to use when sampling this texture.
LODGroup
Texture group this texture belongs to for LOD bias
LODBias
LOD bias, basically the number of miplevels to drop before uploading the
texture. Can be negative and is additive with the LODGroup's LOD bias.
SourceFilePath
Path resource was imported from.
SourceFileTimestamp
Time resource was imported.
