How can I achieve render image like advertising?

Hi guys,

I start with this: http://www.daz3d.com/lindsey-for-sunny-7

I use exactly the same character, do not modify anything, add 2 spot lights with "rectangle" light geometry.
Skin can be acceptable but the eyes is not clear (check attachment).

Does anyone know how to make the render just NEARLY the same as advertising? For example this picture:

I already read many articles about eyes, skin... but can not achieve even only nearly the advertising for "close look".

Any "Ready to render" file sharing or setting screenshot is perfect so that I can study from that.

Thank you

The promo images don't appear to be using spots from the reflections in the eyes. They look like possible HDRI studio images of soft boxes or windows,  You also may have to render for a bit longer.

Close ups of eyes take a lot; they are reflective, refractive, transparent, translucent, and of course: glossy; all of which take time to render.

Not only that, but you have a closeup of the face in general including the hair; all guaranteed to make a decent computer cry like a baby.

Just an HDRI will render the quickest, but when you start adding a number of lights it can have an effect; also, if there are a lot of shadows that is going to cause issues too; but it's mainly the eyes, they are just complicated.

Thank you Kevin Sanderson and nicstt,

For rendering, I use default setup with "dome & scene" render. Do you have any suggestion for lighting? How to increase render time?
It is already longer when I move camera near to the eyes compared to render this character. I already tried with many difference lights, all cause fireflies. Spot lights is the best I could achieve.

For the eyes, I know it is very complex, but I think the character already setup correctly for that... isn't it?
On the description, I do not see any mention about other eyes package, just clothes and hair...

You could do a composit of renders. Do the eyes seperately and photoshop them in. It also looks like vendor used their own personal setting on the skin. I would contact the vendor for tips to get same kind of render. There maybe postwork involved.

If you want to increase how long the render runs for, go to render tab

So

Render Settings > Editor > Progressive Render > Various Options

Max Time, Max Samples, Rendering Converged Ratio: these three are the main ones to change to increase the amount of rendering.

Max Time (and the others) can be increased beyond the maximum allowed in the default, by clicking on the little Cog on the same 'line' as the name. Click on it then select > Paramter Settings.

There is a minumum and maximum option, and next to it a checkbox with 'Use Limits', either remove the check, or drastically increase the number of seconds: 3600 seconds in an hour, so default is two hours.

Edit to add the image.

Also under Render Settings, go to > Environment

The 'Environment Intensity' could be increased to give more light. Be careful of having too much.

Double it; if that is too much, split the difference, and halve it; if not enough double it again, and halve the difference if that is too much.

Thank you nicstt,

I will try but I do not think make more time will do any better for the eyes, since it is like that from 50% -> 100% when I do rendering with default setting...

It's seem like I have got the point.
Thank you guys.
