Duplicate Default Iray light in 3Delight

Is there someway to duplicate the default IRay Light in 3Delight so that in doing comparison renders the direction and brightness of the light at least can be taken out as a variable?

    In Studio...not very easily.

    The closest you can come (I assume you aren't asking about photometric lights, but the sun/sky/HDR) is to use UberEnvironment, with all the bells and whistles on (bounce/indirect, very high samples, directional shadows, etc). And there is no direct 'levels' comparison so that would be pure guess work.

    But in 3Delight in general, there are closer lighting solutions, it's just nearly impossible to import those light shaders into DS, due to interface limitations (among other things), but the support scripts for them would be a nightmare to create by hand...which would need to be done to get them to work.

    Yeah..just the default HDRI.

    Using one of the Core Light presets I got close...just trying to eliminate variables.

    Iray is a full global illumination light...so you'll need all those features enabled to be close.

    Agreed. I tried to do similar a few months back when Iray came out. Ripped out my hear for a month, and was not able to get the same results inside a box with just a color-scale cube.

    The light controls are incredibly different from 3delight to Iray. The surface shaders are completely different, and how light is calculated as well. Every single thing is different almost.

    I did get close, and then life dragged me away for two months, and I've yet to get a chance to figure out where I left off with that project.
