How do I use models from here in Blender?

[CosmicLoop]

Okay, this MAY be a stupid/unhelpful answer, but I'll pitch in what I know. Believe it or not Blender doesn't actually show all the import/export possibilities at first. You gotta go to File, then User Preferences (or ctrl+alt+U) and it's basically a checklist from there (you gotta do this for plugins, too). Also, there are quite a few plugins for Blender, luckily. I even found some for PMD/MMD. Anyway,,

So now I'm googling around and I was reminded of THIS for SMD : https://developer.valvesoftware.com/wiki...urce_Tools ...idk how helpful it will be but it's worth a try. I think I tried once quite some time ago, but knowing me I probably missed a big step lol.

I also found this for SKP : http://blender.stackexchange.com/questio...-skp-files ...Again, idk how helpful

Googling for RDA gave me smoothies

Also if you're like me you might end up using multiple programs to import/export things to have everything be just the way you like. Right now on me (besides Blender) I have 3D Coat and AccuTrans3D, tho I hear good things about Metasequoia.

idk i hope i helped at least a little bit, i'm feelin pretty tired/sneezy right now so sorry if my typing is kinda wonky
