This page provides information about the UVW Mapping texture in V-Ray for Blender.


Overview


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


Node


Uvw Channel TexInput socket for the UVW mapping channel of the connected Bitmap texture. Note that the first possible index of the UVW Channel is -1.

Uvwgen  Allows a UWV modifier to be attached to determine the UVW placement of the texture.




Properties



Layer – 

Clamp U/V – 

Coverage U – U values are remapped to 1.0.

Coverage V – V values are remapped to 1.0.

Mirror U – When enabled, every other tile outside the [0;1] range is mirrored in U.

Mirror V – When enabled, every other tile outside the [0;1] range is mirrored in V.

Noise U – Noise magnitude multiplier in U direction.

Nose V – Noise magnitude multiplier in V direction.

Nsamples – Sets the number of UVW transform samples.

Offset U – Offset is added to U before mirroring (after wrap, coverage, clamp).

Offset V – Offset is added to V before mirroring (after wrap, coverage, clamp).

Repeat U – Multiplier for U values.

Repeat V – Multiplier for V values.

Rotate Frame – Rotates the frame after applying UV noise.

Rotate Uv – Rotates the UVs after mirroring.

Stagger – When enabled, tiles in the V direction add +0.5 to the U value for a 'staggering' effect.

Translate Frame U – Translates the frame in U direction after applying rotate_frame (and before wrap, coverage, clamp).

Translate Frame V – Translates the frame in V direction after applying rotate_frame (and before wrap, coverage, clamp).

Uv Set NameThe name of the UV channel that is used.

Uvw Channel – 

Wrap U – When enabled, U values outside the [0;1] range wrap back to [0;1].

Wrap V – When enabled, V values outside the [0;1] range wrap back to [0;1].

Type – Specifies how the texture image is projected onto the object:

Flat
Triplanar
Camera Mapping
Spherical
Cylindrical
Cubic

Fitfill

U AngleU Angle – Specifies the U Angle when the Type is set to Cinema 4D Spherical or Cinema 4D Cylindrical.

Film Gate W –

Ground Position

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

Duvw Scale – 

Ground on – 

Ground Radius – 

Mapping Type:

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

None
Tile
Mirror
