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 Tex – Input 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 Name – The 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
Fittype
U Angle – U Angle – Specifies the U Angle when the Type is set to Cinema 4D Spherical or Cinema 4D Cylindrical.
