Luxus IBL Presets
Following an example render in Rogerbee's thread I thought I'd share some presets with you guys for image based lighting solutions. These IBL presets don't merely light your scene, but can also act as a backdrop to add skies and other detail without the need for skydomes which might otherwise extend rendering times. Each preset has a 'sun' positioned to line up with the IBL for more accurate shadows and lighting, as well as a textured sphere to act as a guide for positioning your light appropriately.
The sphere is set to a null material so it won't appear in your render and is merely there as a guide. Without further ado, here are the links.
For those who wish to add these presets to your Smart Content tab, you can also download the metadata here.
Note, these were originally posted in the Luxus Discussion II thread, but I've given them their own topic so as to make them easier to find.
Addendum: If you intend to add your own background to a scene, these IBL's will still function well for that purpose. Be sure to check the 'Output Alpha Channel' option in the Export to Image submenu of the Luxrender GUI. This will export the image with all of it's image based light intact, but will not export the background provided by the environmental light.
