Use this area to control the VRAY caustics in your scene.Ĭaustics In optics, a caustic is the envelope of light rays reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface. For example if you have QMC for primary and Light cache for secondary, this rollout will be replace with a QMC settings rollout followed by a LC settings rollout. Note: If you plan to not use an IR map in your GI calculation, these settings wil not be available. Under options I like to have show calc phase checked just so I can visually see the IR map calculation. Mode: For stills, single frame is fine but for animations, Add to current map or Incremental add to current map works well and speeds up the IR map calculation. High preset is usually good enough for me usually. You can pick from any of the pre-defined presets or manually enter settings for a custon IR map. The IR map is one of the methods VRAY uses to calculate global illumination. Notice you also have some options for post processing and GI caustics. I typically will use the default Irradiance Map (IR Map) for primary bounces and light Cache for secondary bounces. Note: For the most part I use the default settings here (Adaptive Subdivision with area filter) Here you can choose the type of Image Sampler as well as the type of anti-aliasing filter. To assign an override material simply drag a Vray material into the box that says None. Note: I often use this section to globally control displacement, lighting and the override material. By checking or un-checking the boxes you can easily enable or disable many of Vray’s key features. Also it has some features that the rendered frame window does not. Basically it allows you to render your images in a different window other than the default rendered frame window of 3DS MAX.

The Vray frame buffer is a cool feature of Vray. Click the box for the Production render shown in red.Ĥ. If you just received Vray or are new to max, remember you need to set Vray as the current renderer before you can access its settings.ģ. If you are having trouble configuring V-ray, optimizing your V-ray render times, or have a huge scene where the render time is just taking too long, then have a look at this free tutorial : Its a great read for beginner and pros alike! With this tutorial you will have a much great understand of the V-ray rendering engine. In this tutorial, we go about explaining every single Chaos Group V-ray 3.0 setting in detail.
