scaleUV operation
scaleUV(uvSet, uFactor, vFactor)
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.
uFactor float A factor to multiply all texture coordinates in u-direction.
vFactor float A factor to multiply all texture coordinates in v-direction.
The scaleUV operation scales the corresponding texture layer by multiplying each of its texture coordinates with uFactor and vFactor.
