Someone here tried to contact the creator of Metasequoia to find out if he could help to find a solution to the lack of possibilities to by licence the application and get access to file export. I don't knowe if he got any answer, does anyone know? In the mean time i did write a small application to test to translate the Metasequoia file format to Wavefront format and as it seemed pretty easy to do . In the current version I only transfer the objects geometry and it has worked fine this far (on my own models). Is this kind of application of any interest?
