Thanks, exactly what I need right now :D

Do You plan to make tutorial vid about GI and radiosity? That would be great (ducking just in case I've missed it)

yes...just need to clone myself a few times...I have it on my looooooooooong list of videos I want to do :)

Thanks for that William. I wasn't sure what the angle did. Now I am in the know.:dance:

I love dome lights and how you get soft shadows without doing anything :D

Downloading the new set of videos as I type.

Many thanks William and keep them coming :thumbsup::thumbsup:

The Dome Light is great, but the rendering hit to get high-quality soft shadows is huge.

I was all set to use it on an outdoor scene, around 140,000 polys, but the render time went from 21 secs with a Distant Light, to 8 mins 40 secs with the Dome Light set to a quality of 12, no GI and no textures yet.....

I set the angle to just 1% - 1%-5% seems to be a good range for mimicking sunlight shadows - and maybe 12 is a bit high for quality, but all the same, these new lights are a great advert for getting the fastest hardware you can afford :)

Looks like my old dual-core's days are numbered for LW at this rate.....

It's the same kind of hit you take for Area Lights IMHO

The tighter the angle the less quality you need too.

dear james, proton

is dome light relatively better for matching Video footage? HD,SD...video footage. I am asking because new lights are coming and if they improve our current workflow we must switch to them...right...

Best

Better in that it produces better shadows IMHO...more realistic shadows. But it depends on the shot. Sometimes a Distant light is all you need...esp when the sun is high in the sky on a cloudless day :)

Yes, same here. The angle control is about the same thing as modo's "spread angle". I am very happy to see this in Layout now.
I was initially under the impression it was some sort of a GI light, in the way one might take a half sphere, flip the polys and make them luminous, or place a whole lot of lights around the inner polygons to fake radiosity.
And here I was trying to resize it or stretch it, hoping to get it to cover a scene. No go, it doesn't work that way.
Turns out it's an incredibly useful light after all. Thank you. :)

Yes, seems about right from testing such things - I'd just like them to be good and fast!

Tight angles are mostly all you need for daylight, and it's true that a lower quality setting does suffice for medium and long shots, though I haven't tested animating this shot yet.

I have Lightwave 9.3.1 for Mac and I have no Dome Light. Where is it?

It's not in any versions prior to 9.5.
