I've been using IRAY as my go-to renderer for about two months now. I'm loving it for the most part. The ability to change the look so effortlessly using HDR's is probably my favorite part of the software. Again, I'll state that I'm only using one GTX460. This card is not expensive nor does it have a great deal of RAM. I do most of my renderings for daily use at 2400 x 2400 pixels. Any larger and I hit RAM ceilings pretty quickly. That said, many of the scenes I have rendered have upwards of 8 million poly's. I have had to make my HDR images smaller (often times they are enormous, around 40-80mb). I've had good luck getting them down to about 8mb. Of course the actual quality of the clouds and sky in the background does suffer, but you can always save as a PNG file and replace the background easily. The attached images are about 2 million faces all modeled in CAD and then rendered in 3ds max. These renderings are using about 1600mb of the ram. Just sitting idle though, uses about 600mb or ram, meaning the scene is eating about 1000. I modeled these two versions this week and rendered them. Each rendering took about 8 minutes. I could have obviously let it got longer, but it really wasn't necessary, as the majority of the grain was cleared.
PHOTOSHOP TIP
A quick trip into photoshop and using the FILTER, NOISE, DUST AND SCRATCHES, heals the rest. See for yourself. That is a regular part of my work-flow. As you can see; the first and the fourth image are really the same rendering. All I did was change the HDR image and the looks is quite different. You can see a lot more of my architectural visualizations at my website: JoshPabst.com | Again, all of these were rendered originally at 2400 x 2000 pixels in this case and resized for web. You can of course still see some grain in the shadowy areas of image 2 and 4 primarily. These four renderings, because they are schematic, were saved as jpegs; no change has been made to the HDR sky. In the large, originals, the sky is a bit pixelated because I made the HDR smaller. Comments/questions welcome.
