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 – 1 – 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.

V-Ray allows animating Bitmap textures. This can be done by loading an IFL file or by loading a sequence of images. Animation should be enabled and set up as usual.

note
IFL (Image file list) sequences can be loaded by manually copying the file path into the Bitmap texture’s File path field. Keep the Sequence toggle disabled when working with IFL sequences.

type
tip
An IFL file can be manually created by creating a text file containing the image file names, where each image file name is in a new line corresponding to the frame number, and saving it with an .ifl extension.

note
Animating Bitmap texture by using sequence of images is done by loading the first texture from the images location and enabling the Sequence toggle. The image file names have to end with the corresponding frame number, e.g. - Image_001.jpg, Image_002.jpg etc.
Sequence – Enables the use of a sequence of image files to create an animation. Load the first texture from the images location as the Bitmap Image File. The file names have to end with a sequence frame number (001, 002 etc.).

note
Start Frame, Playback Speed, and Playback Type options work only with IFL sequences.
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.

The Bitmap texture's transfer function (gamma curve correction) is automatically adjusted when it is created in any of the following material map slots:
Roughness
Highlight Glossiness
Reflection Glossiness
Fresnel IOR
Metalness
Refraction Glossiness

Opacity
Coat Amount

Copy-pasting, replacing or wrapping a texture does not trigger this automatic adjustment. It is reserved solely when creating a Bitmap in any of the specified material slots.
