Hi! Im having real headaches over image maps in Moray. When I create a box
of 1x1x1,
that i actually 2x2x2 units in size.
1) Why is that!?
And ... This gets hairy when I want to use image maps, this makes it
impossible (so far
for me) to make an Image map occupy a the total area of a Box object!
2) How can I make an image map occupy 100% of a box object in moray ?
Anyone?
Best, wishes
Glenn.

the size of an unit box is 2,2,2 because the value 1,1,1 are vectors from the
center of the obbject (as a sphere).
You can correctly map an image on only one side of the cube scale the texture
2,2,1 and translate it -1,-1,0. For mapping on six sides you must create 6
flat box.
Enjoy these helps in a poor english.

To make an actual 1x1x1 box you need to make it 0.5x0.5x0.5

translate it <-0.5,-0.5,-0.5>
There is a real good tutorial on image mapping at the link below.
While it is for POV-Ray not Moray it will really help you understand
the image map process.

Been there :-) The tutorial is very good, lots of very illustrative images,
and
very "in depth". Thanks for the help, Ill go and check the scale and check
out the scale and translate now .-)
Best wishes,
Glenn.

Select the box object, then press Alt+T to select the object's
texture. Apply the following transformations to the texture:
scale 2,2,1
rotate -90,0,0
translate -1,0,-1
If the texture space is still Local (the default), the image map
should now cover the box's Front face. If you are ever unsure when
applying image maps in Moray, remember that wireframe proxies for
textures can help you align them correctly. For a planar image map,
the proxy is the thing that looks like two green arrows at right
angles to one another, delineating the edges of the imagemap.
To make sure your map is upright, note the "broken" arrowhead is the
"up", and the "closed" arrowhead is the righthand direction of the map.
The tips of the arrow heads therefore mark the upper left and lower
right extents of the image, so if you want to visually ensure the
image_map is positioned/scaled correctly on your object, the proxy
makes you life a lot simpler.
