Mastering the Fundamentals of Iray Lighting and Rendering

Details
You’ve finally achieved the perfect scene in Daz Studio only to discover that it’s not rendering the way you thought it would, or should. Why is everything so dark? Why are the shadows going in the wrong direction?

Wonder no more! Landon Lopez, aka LayLo 3D, will demonstrate to you multiple ways of lighting your scene… Professional Three-Point Lighting, HDRI Lighting, Sky-Dome Lighting as well as producing light by using objects with emissive shaders.

Three-Point Lighting

Professional visual media such as theatre, video, film and still photography use a basic system known as three-point lighting and now you’ll understand it too. Know the purpose of the key, fill and back lights, what they’re all supposed to do, and how they work to complement each other. What intensities of light should you start with? How to create and save this set-up in Daz Studio.

HDR Lighting

HDRI stands for High Dynamic Range Image, which uses a composited image of different exposure values and stores a wider range of colors and levels of brightness. Find out the advantages and uses of these unique images, where to find free HDR images and how to use them in your scene. (By-the-way, did you know that most smart phones will take a HDR image?)

Landon Lopez (LayLo_3D) takes you through Mastering the three basic lighting techniques in Daz Studio and then on to rendering your scene with your lighting. It clearly demonstrates and explains what lights are available, what the setting parameters do, and how to best use them.

He then goes on to cover the Render Settings, Rendering Canvases (which can be used to tweak your lighting inside a graphic program such as Photoshop or Nuke) without the need to re-render your scene, as well as nVidia Draw Style.

What’s Included:

This Tutorial also includes a Bonus Video on the basic lights available within Daz Studio.

Sky-Dome Lighting

Daz Studio comes with a Sky-Dome. Learn how to use it effectively and efficiently to enhance your scene, when to use it, and how to tweak it for just the right look.

Once you understand these different lighting techniques we’ll take it one step further and discuss using them in different combinations.

Render Canvases

NVIDIA Iray: Light Path Expressions (LPEs) is an extremely powerful feature included with the render engine. Daz Studio implements this functionality with “Render Canvases.” LayLo will touch on how to use them to reduce time spent rendering and efficiently tweak the lighting in your scene without having to re-render!

Light Path Expressions allow you to take advantage of modern compositing workflows by being able to isolate any light contribution in your scene, and even on a per object basis, which gives you full creative control in post production to achieve your desired look.

Please note: To take advantage of LPEs you will need a 3rd party compositing program or image editor, i.e. Nuke, After Effects, Photoshop, etc. LayLo will be demonstrating his techniques using Adobe Photoshop.

nVidia Draw Style

What it is? How to use it. Why to use it. All answered and will help to speed up your lighting and rendering process.

Rendering and More…

Then, after we’ve covered these and their options, no demo would be complete without rendering. We’ll take a look at the various settings and how to get the render engine working for you.

Plus, he’ll share some of his tips and tricks about lighting and rendering that’s he’s learned over the years!

Ever since I can remember I’ve been super excited about everything 3D. It all started when I was a kid, I loved video games! I can still remember when the Nintendo 64 came out and playing my first 3D open world game, I was blown away!

My passion and enthusiasm for 3D has only grown with age. I don’t have as much time to play video games anymore, but I’ve found something even better, producing my own 3D creations!

I was 12 when I was first introduced to a 3D modeling program. 3D Studio Max R2.5 was one of the modalities we had available in my high school art class (I was home schooled for two years and skipped a couple grades).

Unfortunately, at the time it didn’t click for me that it was possible to make a career out of 3D. I didn’t make the connection that video game assets were created with programs like 3D Studio Max. It wasn’t until 2013 that I got back into the world of 3D.

In college, I couldn’t decide on a career path and basically took a bunch of random courses. I mostly focused on computer science and health and fitness. Eventually, I graduated with an Associate of General Studies degree when I was 17.

As much as I love building, I started to get bored of building houses. Working on million-dollar homes is fun and fulfilling, but extreme weather conditions and the risk of serious injuries started to wear me out. That’s when I decided building on the computer would be just as fulfilling without the same risk of injury or having to work in unappealing weather conditions.

In the middle of 2014 I created my first successful 3D product and became a Daz 3D Published Artist.
