How do you extend the length of extendable tiles in Lemmix? I've looked in all the documentation and I can't figure out how :-[
Please rephrase the question. I don't know what you mean.
Like how some of the terrain pieces can be lengthened to make them taller (e.g. terrain piece #2 in the Fire set can be lengthened, terrain piece #1 and #0 can also be lengthened or shortened).
For example, the Columns #0 piece has a default width of 64, but when I try to change the number in the "Width" field to something other than 64, nothing happens.
The Width and Height are readonly. My mistake. You cannot change the sizes of terrain/object pieces.
