If you cannot see the place2dTexture
swatch, do one of the following:
Select the texture swatch, then click
the Input Connections button on
the Hypershade toolbar.
If no place2DTexture swatch exists, it
has been deleted or not created (because it’s automatic creation
has been turned off by default). You must add one (see
Create a node),
then connect it to the texture (see
Connect render nodes using their default connections)
before you can reposition it.
