Tutorials and Examples

My first  youTube video! Not exactly a tutorial, but a little bit on canvases in iRay.

Lately, while commenting on images in various groups, two interrelated concepts have come up: iRay's desire for light to render 'noiseless' images and the idea of a 'dark' render. Let's tackle that first one.

iRay is a photoreal render engine. It functions, in physics terms, as a camera. A camera, in the physical world, needs light in order to produce an image. There's no getting around this: it's the way the engine works, and it does a very good job of simulating the physics of real world light.

Final Render

In response to some posts on Facebook, I thought it might be a good idea to demonstrate some lighting techniques in Iray. This is not a tutorial, its what I'd call a practical example. I'm going to build an image, piece by piece and talk about my choices along the way. I will do my best to point out options as I go, but this is not supposed to be an exhaustive resource, just a example of how one might go about setting up their lighting for an image.

When we left off, I had just put in a spotlight to give our main figure some definition and overall better illumination. I'm pretty happy at this point; I've got my light illuminating the scene (and it looks pretty good on the water of the stream) and its doing a nice job highlighting my figure and making him stand out from the background. The fill light I added shows off his physique to nice affect and illuminates some of the detail on his clothing.
