I'm assuming the previous textures didn't experience this, but

fine when I writeln it.

How do you construct `filename`? Looks like it's not properly
null-terminated.
If you followed my (short-sighted) `dup` advice, that doesn't
do null-termination. Since the original strings are
null-terminated, just slicing one more character should do the
trick. I'd put an assert that verifies that the last character
is '\0'.
I.e.:
----
string z = x.data[0 .. x.length + 1].idup;
assert(z[$ - 1] == '\0');
----
Generally, don't pass just the pointer of a string unless you
know for sure that it's properly null-terminated.
If you're using a slice directly, without `dup`-ing, then the
original aiString would seem to be broken already.
Ahh you were absolutely right. I concatenated a '\0' and it
worked. Silly me!
Most of the textures loaded and a really broken model appears,
but I'm guessing that's a result of trying to follow along with a
tutorial written for C++ in D.
Thank you for your help. I really appreciate it. :)
