Basically I came across this nifty little asset library, I’ve found it very each to use and integrate into my project so I would definitely recommend checking it out.
It supports a good selection of familiar model formats and is under the BSD licence which is awesome. You should probably check their website for more detailed information about the library and licence information.

I will and have began to integrate the library into my Engine and generally its going very well. How it all links into the content management system is being a bit hard for me to get my head around and produce a good system. I’ve been trying as hard as I can to keep it simple to understand whilst being flexible. This is the second big part of the whole rendering system in my mind and once this is out of the way the final core element is going to be the shader system. I may post some more detailed information at some stage.
