Thank you! XD
Ya, well, if you ever use them, I recommend Vidro because it's simple. Blender needs a plug-in for PMD/PMX models, and I've never used Keyshot. XD
From what I remember, both Vidro and Blender are free (Though, I think you'd have to get the portable version for Blender...) and keyshot you have to pay for.

That's what I get from this picture. XD
