Your setup may look slightly different but the process will be exactly the same. I am using Max 2014, V-ray 3, and have customized my UI a bit. Please note that this is an intermediate-level tutorial, assuming that the reader knows the basics of modeling, materials, rendering, and navigating the 3DS Max interface. How to light an interior architecture scene with an HDRI-image? Let’s go over how to light a simple scene using an HDRI image. Fortunately, there are some excellent HDRI libraries that offer high quality images for free! There are many sources for great HDRI photography, however the images can be costly due to the great skill and expensive equipment required to create them. There are different types of panoramic images – most of the time you will find spherical images. For these images a bunch of photos pointing in all directions have been made from one location in reality and stitched together afterwards. Most of the time you will find HDRI images that are 360° panoramic photo of the real location. This allows for a great degree of control and realism when lighting your scene that simply cannot be achieved with a standard 8-bit image. Pixels can also have values above 255 white, making it possible for bright pixels to have varying intensity. Simply stated, if pixels are overexposed in the image, the exposure can be lowered and the blown out pixels will contain actual color data for the lower exposures. What makes these file types so versatile is the fact that they are 32-bit. EXR are the most common high-dynamic range file formats. High Dynamic Range Images are ideal for this type of setup as they contain the data for multiple cameras exposures within one file.HDR and. What are HDRI images and how can they be used in 3DS MAX? The most realistic lighting can be achieved by using image-based lighting. While both of these methods are effective, I find that the lighting produced lacks the subtle imperfections and variations of reality. Some artists like to use a standard direct light while others prefer a simulated sun and sky, such as the v-ray sun. There are a variety of lighting techniques to use when creating an exterior light source for architectural interiors. Image based interior HDRI lightning compared to alternative techniques
