In 3ds Max, once you’ve set your renderer to V-Ray (Rendering Menu > Common Tab > Assign Renderer) the tabs at the top of the render setup window will change.
The second tab is V-Ray. That tab has several roll-outs.
- V-Ray Authorization – This is where you set the license server so that you can use V-Ray.
- About V-Ray – This tells you what version you are currently using.
- Frame Buffer – Here you can Enable the built-in frame buffer and change the output resolution if you want to use something other than the resolution you have set in Max. You can also generate previews, render to a raw image file, and select render channels.
- Global Switches – This roll-out is where you can affect things like whether the lights are on or if shadows are on globally. This can be quite handy if you have a lot of lights and are testing since you won’t have to go through and turn every one on or off individually. You can also set it to show GI only, set ray trace, and make global adjustments to maps for rendering purposes.
- Image Sampler – You can turn antialiasing on and off here (defaults to on) as well as select different settings for it. Playing with those settings can produce some interesting effects.
- Adaptive subdivision image sampler – You can adjust the minimum and maximum rate. Clicking Show Samples gives you a good feel for what the adjustments you are making are actually doing. Be careful here, a little goes a long way.
- Environment – You can turn on GI environment override, reflection/refraction environment override, and refraction environment override here, and use the defaults or select a map for each.
- Color Mapping – There are several types to choose from and for each you can make several adjustments. Common adjustments include sub-pixel mapping, clamp output, affect background, don’t affect colors, and linear workflow. Some of the choices depend on which type you have chosen.
- linear multiply – dark and bright multipliers, gamma
- exponential – dark and bright multipliers, gamma
- HSV exponential – dark and bright multipliers, gamma
- intensity exponential – dark and bright multipliers, gamma
- gamma correction – multiplier, inverse gamma, gamma
- intensity gamma – multiplier, inverse gamma, gamma
- Reinhard – multiplier, burn value, gamma
- Camera – You can choose a camera type here (default, spherical, cylindrical, fish eye, etc.). Adjustments can be made to FoV, DoF, and motion blur.
