Dimension Theory and Orestes Graphics also has some great HDRi’s for Iray. Here, we are using the Barcelona Rooftops HDRI from sIBL Archives. a lot of light information in our IBL would be lost due to range limits.Ī decent JPG can serve as a good enough background, but it will not be sufficient for providing good realistic scene lighting.īelow is our Princess of the East image, with just the IBL turned on. This is because the difference in range between our very bright sunlight and everything else will be overly compressed. Using a regular JPG image that only supports 255 values per pixel, is not going to work well for scene lighting. I think about it this way … sunlight is a very strong light source, and its value should be many many times greater than anything else in the scene. The higher the range, the better the results.

This beginner Iray tutorial has more on how I use a HDR image in Daz Studio Iray.
