This page offers information about the UVW Channel node in V-Ray for Cinema 4D.


Overview


The UVW Channel node is used, combined with a Bitmap node, and specifies which UV channel of the loaded texture is read.

In the image, the UVW Channel has Coverage set to 0.5 on all axes. It is then connected as a Context node to a Bitmap. The Bitmap is passed, as a Texture X, through a TriPlanar node before connecting to a V-Ray Material. This is done so that the placement is not stretched on the whole plane. In the TriPlanar node, the Frame Offset X is set to 50. This allows us to place the texture only in our designated area of the object.

Properties



UVW Channel – Selects the UVW mapping channel of the connected Bitmap texture. Note that the first possible index of the UVW Channel is -1.

Motion Blur Samples – Specifies the number of motion blur samples when used with animated texture.




Mapping



Wrap U/ Wrap V/ Wrap W – Wraps the map on its U/V/W direction according to one of the following ways:

None – It is rendered as is.
Tile – Tiles the bitmap.
Mirror – Tiles the bitmap in a mirror pattern.

Crop U/ Crop V/ Crop W – Crops the map on its U/V/W direction.

Wrap Mode – Specifies how to wrap the map:

On 0.5 Boundary
On Integer Boundary

Coverage – Determines how much of the texture frame covers the surface. The default values - 111, cover the entire surface. Reduce or increase these values to enlarge or shrink the texture frame. The values correspond to the Xand axes respectively. Changing these values non-uniformly stretches the texture.
