The floor in this scene was also mapped in the same way; after downloading an MXM from the MXM Gallery, it was adjusted to use Real

Scale and Channel 0, assigned to the floor surface, and then the texture size was adjusted by changing the Tile X and Y parameters while

holding down CTRL+SHIFT.

The main difference between using the explicit texture-mapping tools provided by Rhino and using the plugin’s Real Scale feature is

how the mapping is affected when the object it is working on is changed, i.e. moved, rotated, or scaled. When you use a Rhino

mapping, the size and orientation of which you have carefully adjusted, you stand to lose your sizing work when you modify the

geometry it is mapping. Generally speaking, if you scale the geometry, the mappings will also be scaled, and any real-world

correspondence to the texture-sizes will be lost. If, after scaling the mapping, you move or rotate the object, the mapping may move

away from the object in unpredictable ways.

This is not the case with the plugin’s Real Scale feature. You may move, rotate, and scale objects however you wish; the Real Scale

mapping will be maintained, and the orientation set using the Real Scale Texture Control will not change. It is still possible to make

changes to geometry which will require the use of the plugin’s ‘Refresh Viewport materials’ command (in the Functions toolbar); this is

due to the fact that the plugin listens for changes to geometry, but there are classes of change which do not cause a notification. Even

so, though the viewport-appearance may temporarily become unsynchronized, the underlying data is tied permanently to the object it

is working on.

To demonstrate, here are three cubes, 2.0m, 1.0m, and 0.5m, with a Real Scale texture assigned and no explicit Rhino texture-mappings.

As you can see, the map has four quadrants, and has Tile X/Y of 1.0:

Now here are three identical cubes, using a material which is identical to the first, but with Real Scale disabled. Each cube has had a box

projector assigned to it by way of Rhino’s texture mapping window:

1 2 ... 72 73 74 75 76 77 78 79 80 81 82 ... 100 101
