The ever illusive...

I've reached a certain level of "Nice Render" as most tend to agree..

But I'm seeing things on here that make me want more..MUCH MORE!!

Somebody point me in the right direction.

Like links to and tips concerning.

And when I say "tips", I mean those ground breaking profanity renmoved types where you change one setting on your lighting and DYNAMITE!!

And the more in house the better!! (inside the 4.9 Daz)

Post rendering is great but I'd like to do as much in the program as possible..

Thanx

    Well, it'll mostly come does to choosing the correct texture set and then the correct lighting to hide the texture set's deficiencies. Even I'm getting some renders that look realistic at first glance without a more careful inspection. What helped me most is selecting the correct skin textures, hair, clothing, and light and putting all that into a good HRDI.

    I am working on doing indoor renders without HRDIs to make look good too - not just the character's skin and eyes - those are almost a given with any of the DAZ 3D Genesis 3 characters - but the clothing and the room interiors - which often look oddly out of the last decade compared to a lot of the character renders I see - even when done by the professionals.

    The best tip I can give you is, try working out of your comfort zone. There are loads of things to discover in DS (whichever renderer you are using). Try participating in the New user contest, http://www.daz3d.com/forums/discussion/97041/july-2016-new-user-3d-art-contest-portrait-rendering-wip-thread#latest if not to win, then to learn from all the others. That "make art" button unfortunately hasn't been offered in the shop up to now wink

    Lots of us are chasing that dragon. What Ive learned so far...

    Good materials is critical, and lighting is key. Poor posing results in a manaquin look, never just load a premade pose and hit render, they are great for initial positioning but not final render (outside of test rendering I spose). Look at the tension in teh body, the 'weight' of things.

    Facial expression and eyes also critical, the face makes or breaks realism, especially the eyes (including the direction they are looking, staring off vacantly is usually not a good choice, staring straight ahead also bad) but also the expression. A little goes a long way imho. Then there's hair, imho the weakest link in all this.

    I have been struggling with this from the beginning too, but Im getting better I think.

    /Ow, my shoulder...

    I suppose the first question to ask is which render engine you are using? If you're after photo-realism, you'll probably want to use Iray, because it uses real-world light calculations and imitates real-world materials. 3Delight can use 'cheats' to imitate realism, but to get a truly photo-realistic image means taking on the responsibility of mimicking all of those properties yourself. That means positioning lights to fake 'bounce' light, using fill lights and highlights and so on. It also means your materials need to be really on-key.

    Of course, the upside with 3Delight's cheating is that you can do things which are impossible in Iray, such as ghost materials, full-brightness without casting light and shadowless lights.

    For Iray, HDRI's tend to work better in non-enclosed spaces. Light is projected from outside the scene, as if it were wrapped inside a giant sphere, so walls and other objects would block or deflect the light trying to get in. Windows can provide a medium for the light to traverse, as can any other transparent or translucent object. If you are working in rooms, you'll need to make good use of the available space to light your scene properly.

    I can't emphasise how important lighting can be to your scene. With good lighting your scene will be absolutely transformed. I'm still a long ways off true photo-realism myself, but please feel free to check out my DA as I have a few examples there you can review, including indoor scenes.

    I'd only like to add that there is no quick shortcut for this and it takes lots of experience (trial and error). I've been rendering in 3D for more than 15 years now and true photo-realism is as illusive as it ever was.... but I'd like to think I'm getting a bit closer.

    I never really got to a photorealistic level but if I can suggest one thing to you, it's this. Get colm's Render Studio Iray. I can't stop raving about it. This is using one of the scenes right out of the box. It's now my default scene setup :)

    Wish I could paint like that. That looks good.

    I wish I could paint like this as well ;) It's just a render with M7 and one of the render studio scenes.

    All such very good advise!!

    I spend hours literally making sure eyes "appear" to be making contact with the subject.

    Less is more applies in this arena more often than not. A simple head pitch can change the entire attitude of a render...

     

    Thanx for the input!!
