HDRI

[Josh]

Well looking at a lot of realistic 3D renders, they all state that they are using HDRI lighting in their render. I thought I\'d give it a shot and I\'m amazed at how real this looks.. The reflections, the lighting, the shadowing..wow!

For those of you who do not know what HDRI is...
[quote name=\'Google\'][b]High Dynamic Range Image[/b]

A 2D image stored in a file format with a greater range of luminance values than a standard bitmap image. HDR images are often used as environment maps in image-based lighting techniques to create subtle, real-world lighting effects.[/quote]
Well there ya go..now ya know what it is. Here it is:

0.o that looks really neat, must have taken a while to render though /blum.gif\' class=\'bbc_emoticon\' alt=\':P\' />

Well time for my 2 cents. A hdri render won\'t take very long as a standard radiosity render. This is if you set your settings correct. I use the following settings to get these results. Strength : 250% Accuracy : 70% Diffuse : 1 Samples : 100 min : 20 mx : 200 and here\'s the result. [attachment=622:attachment] To get faster renders you can decrease the strengt to 30 %. The diffuse depth is on 1 here but you can place it on 3 as well.
