3D Impressions Help - Material Picture Scaling & Tiling

Scaling

This determines how the picture is stretched by the different scale percentage properties to the material's surface.

The following descriptions are based on having the Picture Scale X, Y values of 100%. This is shown on tall rectangular object on a wide screen with a gray background.

Scale By Object This is where the picture is stretched to fit the surface's width and height exactly. In the example the picture fits the size of the object perfectly.
Scale By Screen with Overscan This is where the picture is stretched proportionally to match the shape of the computer screen and then scaled to fill the surface cropping any overhang. In the example the picture is flush with the top left of the object, but as the screen's aspect ratio is wider than the object, the picture overhangs to the right.
Scale By Screen with Tiling This is where the picture is stretched proportionally to match the shape of the computer screen and then scaled to fit into the surface, possibly resulting in the picture being partially repeated. In the example the picture is flush with the top left of the object, and is stretched in proportion to the screen's dimensions leaving space for vertical tiling.
Scale By Picture with Overscan This is where the picture is stretched proportionally to match the original shape of the picture and then scaled to fill the surface cropping any overhang. In the example the picture is flush with the top left of the object, but as the picture's aspect ratio is wider than the object, the picture overhangs to the right.

Tiling & Border Color

This determines if and how a picture is repeated across the material's surface.

The following examples are based on tiling along the X direction, using a Picture that is centralized and scaled with X & Y values of 40% and a border color of black. This is shown on a large rectangular object on a screen with a gray background.

No Tiling This is where the picture is only shown once and not repeated. In the example the picture appears once in the center of the object.
Wrap Tiling This is where the picture is continuously repeated. In the example the image is duplicated side-by-side.
Mirror Tiling This is where the picture is continuously repeated, but every other one is a mirror image. In the example the image is repeated with each being a mirror image of its preceding one.
Mirror Once Tiling This is where the picture is shown twice with the other being its mirror image. In the example the picture only replicated once to the left as a mirror image. Also note that the border color has no effect in the direction of this tiling option.
