Place2dTexture is a utility node that controls how a 2d texture is placed onto an object. Normally a Place2dTexture node is created automatically by the system when you texture-map an attribute using a 2d texture. (The Out UV attribute of this node is connected to the uvCoord attribute of the texture node, and the outUVFilterSize attribute of this node is connected to the uvFilterSize attribute of the texture node.)

2d textures are placed on a surface using the surface's UV coordinates. (These coordinates are implicit in NURBS surfaces, but they must be assigned explicitly to polygonal objects.)

The Place2dTexture node defines a texture frame, which is a rectangular area on a surface (in the UV coordinate space) in which the texture will appear. You can control the position, size, and rotation of this frame on the surface using the Coverage, Translate Frame and Rotate Frame attributes. You can controls how the texture is tiled within the frame using the Repeat UV, Rotate UV, Offset, Mirror, Stagger, and Wrap atttributes. These are all explained below.

In the table below, important attributes have their names listed in bold in the description column.

Long name (short name)TypeDefaultFlags
coverage (c) float21.0, 1.0outputinputconnectablestorable
UV Coverage controls how much of the surface will be covered by the texture frame. Its default values, (1 and 1) will cover the entire surface. Reduce these values to shrink the texture frame. For example, if you set Coverage U to 0.5, then the texture frame will only cover half the surface in the U direction.
coverageU (cu) float0.0outputinputconnectablestorablekeyable
Coverage U controls how much of the surface's U-direction will be covered by the texture.
coverageV (cv) float0.0outputinputconnectablestorablekeyable
Coverage V controls how much of the surface's V-direction will be covered by the texture.
doTransform (do) booltrueoutputconnectablehidden
This output tells if the transformations must be applied
fast (fa) boolfalseoutputinputconnectablestorable
Fast is an optimation you can use under certain rare circumstances to speed up calculation in this node. It will only work if Coverage and Repeat is 1, all the translates, rotates, and offsets are 0 and Mirror, Stagger, and Wrap are all turned off.

If you are unsure about using this, it is best to just leave it turned off.

mirrorU (mu) boolfalseoutputinputconnectablestorablekeyable
MirrorU controls how texture tiles are placed beside each other. When MirrorU is turned on, then each copy of the texture will be the mirror image of the ones on the U sides of it, with their shared edge being the (V) axis of reflection.
    MirrorU OFF:

Textures are tiled when Repeat U or Repeat V is greater than 1.

mirrorV (mv) boolfalseoutputinputconnectablestorablekeyable
MirrorV controls how texture tiles are placed beside each other. When MirrorV is turned on, then each copy of the texture will be the mirror image of the ones on all V sides of it, with their shared edge being the (U) axis of reflection.

offset (of) float20.0, 0.0outputinputconnectablestorable

Textures are tiled when Repeat U or Repeat V is greater than 1.

translateFrame (tf) float20.0, 0.0outputinputconnectablestorable
Translate Frame controls the position of the texture frame, relative to the UV origin of the surface. (That is, the corner of the surface where U and V are zero). Increase these values to move the texture frame away from the corner. If you set Translate Frame U to 0.5, the texture frame will be shifted half-way along the surface.

wrapU (wu) booltrueoutputinputconnectablestorablekeyable
Wrap U controls whether or not the texture will "wrap around" in the U direction. For example, say you increase the value of Translate Frame U enough to push part of the texture frame right off the surface. If Wrap U is turned off, then that part of the texture will be cut off and lost. If Wrap U is turned on, then that part of the texture will be wrapped around to the other end of the surface.

When you are bump mapping with the default full coverage, it is best to turn off Wrap U and Wrap V to avoid wrap-around effects on the bump. You should also turn on Adjust Edges in the Bump2d node.

wrapV (wv) booltrueoutputinputconnectablestorablekeyable
Wrap V controls whether or not the texture will "wrap around" in the V direction. For example, say you increase the value of Translate Frame V enough to push part of the texture frame right off the surface. If Wrap V is turned off, then that part of the texture will be cut off and lost. If Wrap V is turned on, then that part of the texture will be wrapped around to the other end of the surface.

When you are bump mapping with the default full coverage, it is best to turn off Wrap U and Wrap V to avoid wrap-around effects on the bump. You should also turn on Adjust Edges in the Bump2d node.
