My brother brought up an issue with IBL.

I ran a quick test with my sphereical environment (the old way of doing HDR) and here are the result.

My sphereical environment:
[attachmentid=14283]

IBL:
[attachmentid=14284]

The Latitude/Longitude map:
[attachmentid=14285]

The red dot is the only visible light in the scene. In my sphereical environment test, a shadow is created because only black light is allowed to hit the area directly behind the sphere. The white dots in the render are created from the whole in the top of the environment sphere.

In the IBL test, red light passes through the sphere.

This is because A:M IBL uses the slope of the patch to recieve color data, and it uses AO to add shadows. This explains why you wouldn't get difined shadows from light sources such as the Sun.

So as of right now, you cannot acheive this look by using IBL in A:M.
[attachmentid=14286]
This is an environment sphere with a light rig. It is only 80% finished and it took 20 minutes to render.

Yves - "...and I'd have gotten away with it too, if It wer'nt for you meddling Bradbury's!..."

Cheers for pushing the boundries, Cant wait to hear from the big man himself. (he'd make a great character for animation...)

Nixie

p.s - i mean no offence to either party, I just enjoy seeing the ongoing events between you lot!

Well, it is still a very good application nonetheless.

I think that if you wanted to cancel out colors after they hit one surface, and didn't want them to continue onto the next, it would take a great deal of calculation and render time, so in the end the IBL+AO quick trick wouldn't be cost efficient. But i could be wrong.

HAVENT WE BUGGED YVES ENOUGH ALREADY!! common he at least gave us ao and a simple ibl to work with

thank you yves.
