I'll give v2.77 a try, then! But I'll give it a try tomorrow when I'm slightly more awake: I feel like I should have my wits about me (such as they are) when I do anything with Blender. In the meantime, are there any tickboxes in the export pane I should tamper with, or are the default values reasonable enough to keep my meddling hands well away?
I should also maybe add that I'm not doing any serious remeshing or planning anything especially ambitious, I'm mostly just curious to see what's possible.
