When I use a texture map on a large surface I can always see the edges
of the map like photo cut-outs pasted together in an array. Is there
a way to "mirror" the map so the edges blend together??? I can't
find a way.
If the maps you're using aren't tileable, you should be able to make
them so by using a paint program to mirror a copy of the image
horizontally and paste it next to the original, and then mirror this
double image vertically and paste again. Now, of course, your
texture map is 4x the size, but things will meet up. Of course,
depending on the pattern, this may look _horrible_!
