Something needs to emphasised in the debate over these two plugins, they both use the same free GPL licensed renderer.

I understand the need to point out the advantages of 1 plugin over the other however when it comes down to actually using the renderer the process all comes down to how the export file is parsed.

If one is proficient in how to handle the lighting and materials for Luxrender than both plugins are sufficient pipelines for export.

I give Pret-a-3D props for jumping on this platform early with developement of Reality but at some point competition was going to come about with that being the only solution and cornering the market.

I myself used Tufosan's plugin in Studio 3 and was able to get what I felt were striking results enough to keep studio 3 on my machine just so I could use that plugin. Once again different plugin(Free) as opposed to Reality and close to the same results with a little more work.

I think it all comes down to what you will except, if you want the plugin to do as much of the parsing as possible and be easier to understand and use and support than Reality would be your choice at the moment, if your willing to do the work in understanding and studying Luxrender lights materials and how it handles meshes and cost is your issue than Luxur would be your choice as it stands at the moment.

Competition is welcome in my humble opinion.
