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.
