Blender's default units are...[drumroll]..."Blender Units" -_- I changed it to metric. I recalled reading once upon a time that 1BU = 1m and just did a quick search to check and the first answer did say that internally 1BU = 1m but other software could infer the arbitrary unit as something other than 1m.

So that might be what's happening with 3dC (despite the fact I've set Blender to metric, maybe it's exporting something special anyway, and 3dC is doing its own thing with units), though it seems from more Google-fu that 3dC's scene scale is a long running problem (lots of people having issues 3dC <-> Blender and 3dC <-> Modo). Guess I'll just have to keep finding equally silly workarounds XD

Yay glad you like the silly comic! Guess I'll do more then, no idea how often as they're super spontaneous XD
