More than likely the issue is in Blender. If it's like Maya, the default units are in cm, and say you make a cube with default settings, it will be 1cm x 1cm x 1cm. It sucks if you already have a lot of assets in that scale in Blender because that means you'll need to resize it all.
But what I'd look for is what are the default units in Blender, then try to scale everything to the real life scale you imagine it being. Then when you import into 3DCoat that SHOULD fix it, unless I'm totally misdiagnosing your problem which I might be 😁
I like the comic :) I wasn't the one who originally asked, but I'd like to see more .
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
