This can be found on the VRay Camera, or in the render setting depending on your platform. You can start by just using an EV value for exposure. Anything physically based will work the same. I HIGHLY recommend you study real world photography in order to better understand what you need to set virtually in V-Ray or any other render engine. This is what controls how your rendering looks of you’re doing an interior or exterior. What you really want are settings for lights and cameras. After that it just increases render time for almost no change in quality. Decreasing the number will make the render go slower and creat less noise. Increasing this number will make the render go faster but it will creat more noise. The only setting that you actually need to change is noise threshold under the dmc sampler. Use the default settings and nothing else. There are no render settings for interior vs exterior. Once you get into render settings, it's about noise and optimizing for speed, that's it. You can do that with the default Vray render settings and never touch a slider. Get just a chair model or something and place it in a white box or on a plane and practice with the lighting and materials until it looks real.
Get some good quality photoscanned materials from somewhere like Poliigon or Megascans or similar and practice making those look photoreal. Depending on the style you're going for, you may eventually want to look into rendering to AOV's and then compositing them in Photoshop or After Effects (if you're using ACES color).Īll that said, first things first, practice your materials.
The other dirty little secret that no one talks about is how much post-processing those high level renders go through to make them truly excellent.
Render settings are more about getting noise free renders than about the quality of the render. Those matter for sure, but everything else has to be top notch before you need to worry too much about it. Thing is, realism is way, way, way more about the quality of the materials, the lighting set up, and the camera settings than it is about the render engine settings. There might be a place to find some good generic/starter settings, some of the presets/default settings in Vray will definitely work.
