Point Cloud Indirect Lighting in 3Delight from Blender

Matt Ebb uploaded a video last month which shows off point based indirect lighting using Blender, his own RenderMan exporter and 3Delight. We all know 3Delight is a commercial renderer, we also all know that at everyone can get a single free license for non commercial work, which allows us to use a production grade renderer with Blender and take advantage of it's power. As such, this is why Matt Ebb has focused on creating the addon for 3Delight specifically, rather than a general RenderMan script.

In this post Ebb writes :

"After fixing some cross-platform issues that people were having with the last few versions, here’s a new release of 3Delight/Blender. As well as the fixes, I’ve included some new stuff that’s been on the backburner for a while – a new point cloud global illumination method. When enabled, the addon will automatically generate a point cloud, and then use it in the render for indirect lighting and environment lighting.
It’s just doing one bounce of indirect lighting, in the future it should be reasonably easy to add more bounces via photon mapping in the point cloud generation stage. Eventually I’d like to make this a bit more advanced, with a more modern design for the lighting/shading pipeline and more control over baking pre-passes, but for now (especially since I’m quite short on time ) I’d rather get it out and working in a simple, automatic way so people can use it.
I’ve tested this on my mac, and in both Linux and Windows XP VMs, but as always, if you have any problems on your system please let me know."
