This page provides information about the Bitmap texture in V-Ray for Rhino.


Overview

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.

The Switch To Advanced Settings () toggle activates the Advance Settings mode, giving you access to a larger number of settings for modification of the Bitmap texture.

Any texture can be replaced via the Replace With New Texture () button, which activates when you select the texture to be replaced. If the texture is an instance, all copies are changed as well.

 

 

Image File

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.

Color Space – Specifies the type of color space used by the bitmap.

Screen Space (sRGB)
Rendering Space (Linear) 
Custom Gamma Curve

 


Sequence

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 backwards repeatedly, making every animated sequence loop smoothly.
Hold – Freezes the bitmap animation on the last frame.

 

Color Manipulation

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 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.

 


Crop/Place

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.

 


UV Noise

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

UV Noise – Enables or disables UV Noise.

Amount – Controls the amount of noise.

Size – Controls the scale of the noise function.

Levels – Controls the noise color distribution.
