Non serious LuxRender test because the other project has temporarily burned me out.
For the lighthouse I need to do more small rocks, upgrade the water, grunge it up and such...........
Anyways it's Not my model but my materials and lighting. Took me 20 minutes to setup(I've never touched lux before),
the exporter plug-in and Blender experimental build is sorta buggy.

Yes there are many glaring issues, render noise because it takes hours to let it go.
Material issue I dunno what to do about, and the materials need tweaks.
But whatever not going to make it pretty as it's just an acquittance test with LuxRender.
The benefit with LuxRender is it's physically correct and handles color in a much more realistic way, compared to faster biased rendering engines such as Blender internal.
