Rendering in layers advice needed

LiquidWarehouse

I have a scene I needed to render in iray that is too big for my 1080ti, I need to split it into layers or sections but there are overlapping elements front to back with a ground plane that if I don't include makes the shadows cast for some objects look weird. To top it off there is an atmospheric haze effect across the whole image. If I render the objects and characters without the background the lighting changes noticeably as it also does without the haze. Any help would be great, I've also heard about canvases but can't find a guide other than for lighting. Cheers all

Are you familiar with DAZ's canvas feature? 

Here is a link to a forum post on that process. I'd offere advice, but i've only just tarted playing with that feature myself.

There is also a nice tutorial on Deviant Art by one of the DAZ PAs I beleive, with a simplified step by step.

Followed the tutorial but unfortunately even creating nodes with certain objects, the entire scene is still loaded into render memory which makes sense as it has to perform those calcululations on the geometry and surfaces.

Think I am going to have to just render in groups layer and mask which means rearanging the scene slightly :(

FWIW, even if you're doing your final renders with IRAY, the 3DL-based render-pass toolkit may be useful for mask creation in your project:

If you do use this make sure all your surfaces are 3dl default or other shader, it won't recognise Iray uber shader or at least it didn't last time I used it.
