The Bulge texture map is similar to the Grid texture but adds in the feature of acting as if the grid lines are constraining the texture and the texture is inflated from beneath it. It is most often used as a bump map, but can also be used to simulate transparency as well. When used as a bump map it gives an inflated look.

UI Text Box

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

U Width – Sets the thickness of the horizontal lines.

V Width – Sets the thickness of the vertical lines. For more information, see the U Width and V Width example below.

Color Manipulation


Invert Texture   Inverts the RGB texture values. 

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

Color Gain –  Color corrects the texture by multiplying the RGB color values in the texture with the RGB color values specified here. A texture map can be used for this parameter, as long as the checkbox is enabled. 

Color Offset  Color corrects the texture by adding the RGB color values specified here t the RGB color values in the texture. A texture map can be used for this parameter, as long as the checkbox is enabled.  

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.

Texture Placement

...

width50%

Type – Controls how the texture is positioned on the geometry.

2D (UV Channel) – The texture uses the object UV coordinates.

Environment This mode is currently not supported in V-Ray for Revit.

2D (UV Channel)

UV Channel/Set – Specifies the index of the mapping channel data to use. A value of 1 takes the first available channel.

Repeat U/V – Determines how many times the texture is repeated in the 0 to 1 UV square.

Lock U/V Repeat – Locks the U/V Repeat.

Offset U/V – Controls the texture offset in the U and V direction. 

Rotate – Rotates the texture (in degrees). 

Tile U/V – Tiles the texture in the U and V direction. If the option is disabled, the Default texture color is used outside the 0 to 1 UV square. Default color is found in Parameters > Color Manipulation.

Mirror U/V  – Mirrors the texture in the U and V direction separately. The option cuts the texture in the half flipping one side vertically or horizontally. This can be used to avoid seams in-between non-tileable repeated textures. 

Double-sided – This option should be enabled only if support for unique front and back face UVS is required. If enabled, channel "n"is used for front-side UVS and channel "n+1" is used for back-side UVS.
