The Bitmap texture has a versatile use, allowing a bitmap image to be loaded as a texture.

The Bitmap texture settings are organized in Basic and Advanced modes. You can switch the mode from the toggle button under the Preview Swatch or globally from the Configuration rollout of the Settings tab.

Some options are available only in Advanced mode.

File – Specifies the file from which the bitmap is loaded.

Filter Type – Specifies a type of filter to be applied to the bitmap.

Sharp Isotropic - Sharp and accurate isotropic filter. Produces results that are close to the results with disabled filtering with less AA samples required.
No Filter – No filter is applied. 
Mip-map – Depending on the distance from the camera, the texture is rendered in full detail (when closer to the camera) or blurred, if it is far away. 
Summed-area – Applies a summed-area filter. It is not recommended to use this filter.

Filter Blur – Specifies the strength of the blur filter applied to the bitmap.

Transfer Function ² – Specifies the transfer function for the loaded image file.

None – No correction is applied.
sRGB – The loaded image is considered in sRGB transfer function.
Custom Gamma Curve – The transfer function is controlled through the Gamma parameter.
Auto – Automatically determines the color transfer function. If a bitmap file name contains the string "_srgb" the transfer function is sRGB. If a bitmap file name contains the strings "_lin_srgb" or "raw", no correction is applied. For bitmap files with 8 bits per color component and 3 or 4 color components (like png, jpg and other), the transfer function is sRGB. In all other cases, no correction is applied.

RGB Primaries – Allows you to manually override the RGB primaries of the Bitmap.

Raw – No transformation is applied to R|G|B colors. This option is suitable for normal maps, linear textures and textures controlling float value parameters.
sRGB primaries – The loaded image is considered in sRGB color space.
ACEScg primaries – The loaded image is considered in ACEScg color space. It is recommended to use this option when the texture is saved in ACEScg color space.

Gamma – Specifies the gamma curve correction applied when the Transfer Function is set to Custom Gamma Curve.

Start Frame – Specifies the start frame at which the map animation begins.

Playback Speed – Speeds up or slows down the animation rate.

Playback Type¹ – Determines what happens after the last frame of the bitmap animation, in case the animation is shorter than the scene.

Loop – Causes the animation to repeat over again from the beginning.
Ping-Pong – Causes the animation to be played forward and then backward repeatedly, making every animated sequence loop smoothly.
Hold – Freezes the bitmap animation in the last frame.

Invert Texture – Inverts the RGB texture values.

Invert Alpha – When enabled, inverts the bitmap alpha values.

Alpha from Intensity – Uses the texture RGB intensity/luminance as an alpha channel.

Color Gain – Corrects the color of the texture by multiplying the RGB color values in the texture with the RGB color values specified here. A texture map can be assigned here.

Color Offset – Corrects the color of the texture by adding the RGB color values specified here to the RGB color values of the texture. A texture map can be assigned here.

Default Color – Specifies a default color used for polygons with no valid UVs. In case the map is not tiled, specifies a default color that is used outside the texture square.  When a texture is selected, it overrides the color as long as the texture checkbox is enabled.

These settings are available only when you switch to the Advanced mode.

Placement – Specifies the type of placement to be used.

Whole Texture – Uses the whole bitmap.
Crop – Uses a section of the bitmap.
Place – Adjusts of the position of the image.

Width/ Height  – Specifies the width/height of the bitmap. A value of 1 specifies the full width/height. 

Jitter Placement – Specifies the amount of displacement to be applied in order to produce better anti-aliasing.

These settings are available only when you switch to the Advanced mode.

Amount – Controls the amount of noise.

Size – Controls the scale of the noise function.

Levels – Controls the noise color distribution.
