translateUV operation
translateUV(uvSet, uOffset, vOffset)
uvSet float Number of texture coordinates set (integer number in [0,9]). The numbering corresponds to the texture layers of the material attribute, see also Texturing: Essential Knowledge.
uOffset float How much to translate in u direction.
vOffset float How much to translate in v direction.
The translateUV operation translates the corresponding texture layer by adding uOffset and vOffset to each of its texture coordinates.
For example, to move the texture to the right by half of the width, use translateUV(0, 0.5, 0).
