I add it in after the Key, Fill, etc. The screen effects are additive so you can add it in whenever.

I meant to say the volumetric layer…

I usually render the entire scene when I can. Sometimes when there is occlusion, I do not.

I understand the layers (have been working with Photoshop for a long time). Just wanted to know whether you render the entire scene for each layer. I suppose you must or else the effect of the light itself would change.

Thanks! For replying and all your articles. You’ve been IMMENSELY helpful in helping me get a hand on DAZ. I’m much looking forward to checking out your postwork articles. 🙂

My new images have at least all of those lights. I combine them in PS using the Screen option as described. I can set the intensity of each light by controlling opacity and duplicating layers.

I render those lights separately based on the light positions described in the first article – https://thinkdrawart.com/how-i-light-my-daz-studio-iray-scenes

So I have Key, Fill, and Back lights. Then I turn on *only* Key light, render, save. Turn on *only* Fill light, render, save, etc. It is possible to do it all at once with canvasses, but there are other limitations there.

I dont understand where you take the ligths or how you extract there on the iBL?

Opps, sorry for the late reply. Lots of stuff cropped up this month. In terms of canvasses, yes I tried it although not very deeply. Like you, it seemed cumbersome to me with no file type choices. Lux Render has a great “canvas” type system. Hopefully, DS will build this up in the future.

Btw. this tutorial has some cool functionality of canvasses. https://www.deviantart.com/snowsultan/art/Iray-Canvas-Tutorial-565641976
