I love the idea behind JanusVR but what is preventing people from making good looking 3D models &amp; environments? JanusVR is absolutely wonderful and I love it to bits but everything has a very *early internet* feel to it. Things look unpolished, making the environment look more like a test bed than an actual place to spend considerable time in. 

What is the reason for this?

Is it the limitation of the engine? Or is it to address the PC requirement concerns (ie. low fidelity so most people can run it smoothly)? Or is it because there's no good tools to model? Or do people not care about putting more time and polish into 3d modelling?
