IRay vs Vray/3DSMax kinda challenge

boisselazon

Hi everybody

As a (bad) combination of newbee and not-able-to-install-daz4.8IRay-yet, I cant answer myself to this topic. But I'll have soon a (big) bunch of differents renders to do. So, this question is strategic to me.

I've seen many nice renders in several render engines. 3Dlight is nice but I tend to prefer Iray style or Octane, Vray...
As we now have a nice additional render engine named Iray wich can benefit of hardware acceleration, I ask my self the question: can we do or approach or get as close as possible to the renders I have seen that make me think "that's what I want".

I'm pretty sure that this topic will benefit all the readers and even the contributors because Iray is new to US and experience is the base.

Everything came from this (excelent) video:

The final render is done via 3DSMax with vray and you can see them there (if you don't want to see all the video)

the guy uses this skin that I really love:

Here is the "chalenge".
Could you guys share your experience and show us a render as close as possible of the images above.
Even better: if you can use the Valerie skin, it should give us a perfect comparison (without the morph..)

in addition to this, could you give us the render time (with harware spec, example: 12mn with GTX980..)

Reward: the admiration of all folks out there looking at your pictures and saying out loud "wow!!!":coolsmile:

many thanks in advance.

I'm trying to do promos right now so I don't have time to set up a scene.. However, there is really no reason that should not be pretty reproducible since we know the skin used. The differences would be the light set used and the settings for the skin. The primary difference between iray and vray are how the do calculations and that vray is progressive so you can see how it is doing much faster. As far as reproduction goes the only thing that would take any time is setting up the skin texture properly with Iray settings and finding a light (HDRI) that gave the same sort of color to the scene.

If I did that render on my old machine it would be a pretty long render for a 1000x1200. Maybe 8 hours? That said I was CPU only and had 4gb of ram total. It was 7 years old and had a long hard life. I got a new computer this week with 16mb, an i7 and a nivida 970 (4mb). On the new computer I would guess the same render would take no more than 10 minutes and possibly less.
