# [lltx] LuaLaTeX and FontExplorer Pro

I am experimenting with MacTeX2010.

I have run into one problem. I use Linotype FontExplorer Pro (2.5, on Mac OS X 10.6.3) to manage my type library. With this simple document:

%%==8><--%%

% !TEX encoding = UTF-8 Unicode
% !TEX TS-program = LuaLaTeX

\documentclass{article}

\usepackage{fontspec}

\setmainfont{Centaur MT Pro}

\begin{document}

This is easy.

\end{document}

%%==8><--%%

I get the following from the console:

%%==8><--%%

luaotfload | Updating the font names database:
./luatest.tex:8: Font \zf at basefont=Centaur MT Pro at 10pt not loadable: metric
\let
l.8 \setmainfont{Centaur MT Pro}

?

%%==8><--%%

Will Robertson explained: "Unfortunately LuaLaTeX doesn't use the actual font system in Mac OS X, it just cheats and looks in known locations like ~/Library/Fonts/ and so on. This is a limitation in LuaLaTeX that can only be fixed by someone who knows what they're doing :)"

Would it be possible for Lua{La)TeX to use fonts activated by font management software? (WR also went on to explain that it is possible to use mkluatexfontdb to widen the Lua search area).
