In reply to Matt. They are the only lights in the scene (no HDRI). You can turn up the luminance of those lights to get things brighter. However, they will be combined with other lights and they can be added multiple times in post, so they don't need to be very bright.

Hi! Thanks for this amazing tutorial. I had one follow up question – when you’re rendering your light passes, are you leaving the HDR environment light on with the key fill and back light passes? Or when you render those passes are they the only lights in the scene?

I found those passes to be supremely dark by themselves. Would love your thoughts!

In reply to Kurt. Very nicely done! Yeah, I usually turn down the diffuse of background items. There are also ray props, but I like using atmocam because then the rays and shadows cast are based on the objects in the scene.

I took some of this advice with this image. It took a few tries to get the lighting right. Had to tone down the rock diffuse color a lot to get the balance I wanted. https://polyrender.deviantart.com/art/Fallen-Angel-744147082 I used atmocam for a volume layer and then made the rays by creating a mask using Filter Forge. Actually just using FF would probably be a lot faster than messing with volume. 3 renders at 2000 X 1600. Each one only took about half hour a piece.

In reply to Kurt. Yeah, I use Atmocam is a separate light pass, so that I can limit it to specific lights. It may be possible to do this in a single pass in Iray with canvasses, but I haven't really looked deeply into that.

In reply to Kurt. Oh wait, I guess I already do that with spot lights, only I usually use sphere or disc.

Excellent. I didn’t know you could convert spots to meshes. Will have to try that trick. Have you written a how to on your Iray Atmocam usage? I have it and sometimes use it but it looks like you are confining it to a small area. Or perhaps it is just one of your light passes. I used to render in light layers with 3DL but haven’t done that much with Iray since the more light, the faster it goes (though, with 3 GTX-1080s, I don’t worry about speed much).

In reply to lanny. I have not done that before, so have no idea. Google probably knows, and Dimension Theory has a bunch of HDR light sets that may help.

In reply to Carl.

Like you click the eye to turn the ibl light while he other lights are off then render, then turn on the key light while the other lights are turned off then render, etc?

Yes, that is what I currently do.

I’d also ask this just to be sure, is IBL the environment light?

Yes, that is exactly what I am referring to. 🙂

Several ways in which I light interior scenes –
