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. Kindly share your comments and any way out to do same.Image based interior HDRI lightning compared to alternative techniques The website showed the tutorial of Vray on 3dMax but the GUi of Shetchup Vray is different and im unable to do so. so in result, object's shadows appear on and feels like shadows on the background image. The one way i found on some website that to make the ground with some transparent effect but receiving shadows. Hi, I am having same problem of no shadows of the models when use HDR images as background. So, keep in mind, always put something under your models, and put it on the higher ground, because you will never get the perfect match with the hdri. My biggest problem was the fact that, I can't get the shadows of my models on the background( like Hypershoot does very well), so I had to make some geometry to put my models on top, to get what I want.

I would make sure you are using the most current as there are some significant improvements. Just make sure the light source direction in Vray matches the light direction in the image you will be comp'ing into.Р”В¬ould you post an image of your settings? If we see something that might not be right we can point it out to you that much easier. If you render using alpha maps this will makes comp'ing the render into the image that much easier. All of that for us is done in PS after the render. The second thing is I personally do not try to comp my render into a background in Vray. The HDR image used for lighting needs to have the 'environment' tab checked so it is using the image only as a lighting source and not a background image (hence the difference). Not knowing how much you know or don't know I will start with this: It does not cover everything but gives you a good start.

The manual is fairly well written and to the point so I would start there too. It is really a matter of knowing your equipment and taking the time to learn the settings within Vray. What is 'fast' on one persons machine may be slow on another.

We are rendering to 10 other machines using my MAC as the parent and it has drastically cut our render times (but again this really depends on the scene). Anytime you can split a render up and get the help of other computers power it will make things quicker. It makes a world of difference even if the other computers are not fast machines. My first suggestion is render to every available computer (DRSpawner). Lights and how many lights are in the scene As far as speed goes it is dependent on so many variables: These are some really good and well written tutorials for some standard set-ups.
