--- Comment #4 from Matteo Bruni matteo.mystral@gmail.com 2010-09-21 05:43:28 CDT --- Ah, it indeed happens to me too if I use builtin msvcr100.dll instead of the native one. A quick look to the +relay logs reveals that with builtin msvcr100 the application never tries to open cube.mtl and then the texture images.
