Quote - Hey BB.. just had a question/thought... What's the best node setup to use an image as background? I'm sure you prolly have a trick or two up your sleeve about that setup.

Wouldn't a good default load setup have the ao applied on the ground plane, and a graphic backdrop with whatever node mojo you'd have for it?

Granted, no two renders are the same, but a good starting point would be useful.

Hmmm..... can a node setup be done for a proceedural gradiant "sky" effect? (I lightwave, you can define the highest sky point as one color, the bottom most as another color, and adjust the blend point with a setting. Maybe a sky gradiant like that could be setup in poser, with a number of gradiant colors, so you could simulate, say  a sunset "sky"? That could possibly even be hooked into somehow as additional base sky "lighting" of objects?

The moon thing got me wondering is a gradiant could be setup for the sky, rather then loading a prop, and faking a gradiant sky with that.

 

For an image on a background, load a one sided square. Set Diffuse_Value = 0, Specular_Value = 0. Attach your image to Alternate_Diffuse. Done.

Yeah its probably a good idea to configure your ground plane to have an AO node by default, and save that as your default scene.

As for gradient sky - sure - I do it all the time. In my default scene, I have a giant sphere. I load any gradient I want using nodes. We need a new thread for this. I'll be back.

As for using the environment sphere for lighting as well, you need to have an image for the sphere in panoramic format, and also an Angular Map conversion of that image for your IBL. I discussed this in a few other threads over the last couple weeks.
