Seamless textures will tile end to end with minimally noticeable seams.
Positioning Projective Textures
When Projective Scaling is selected, you can position the texture projector by using the Elevation and Azimuth
controls. These controls, familiar to astronomers, defi ne a location on an sphere of space surrounding the object face.
Elevation can range from –90 to 90 with 0 being the horizon, -90 being directly underneath and 90 being directly
overhead. The Azimuth value defi nes an angular position that starts where the X-axis intersects the horizon at 0
degrees and proceeds in a clockwise direction around the horizon until it returns to the X-axis with a value of 360.
The X, Y and Z values defi ne the offset of the projected texture along each of the axes.
