General

In this tutorial we will discuss the universal VRay 1.5 settings.

Of course, there is no universal answer and it depends on the desired render speed and quality, but here is a set of settings that we have found to work very well for still images in many situations. Please note that these settings are not optimal, in the sense that with enough tweaking, you can probably get similar quality with faster render times. The beauty of these settings though, is that they require almost no tweaking and you are guaranteed to get a nice result in the end.

Setting the VRay renderer

1. Set VRay as the current rendering engine (start with the default VRay settings).

2. In the Image sampler rollout, switch to "Adaptive QMC".

3. Set the "Max. subdivs" to 100 (one hundred). Leave the "Min. subdivs" to 1.

4. Set the primary GI engine to QMC GI. Do not change the subdivs.

Set the secondary GI engine to Light cache.

5. Set the light cache interpolation samples to 5.

6. Set the QMC Sampler "Adaptive amount" to 1.0.

7. Un-check the "Clamp output" and "Sub-pixel mapping" options in the Color mapping rollout. The "Sub-pixel mapping" check-box,

allows you to use any type of color mapping.

8. Typically you will need to adjust the Noise threshold as the default produces too much noise. A good value is 0.005.

You can also controll the noise directly from the AA (Image sampler) rollout. Uncheck the "Use QMC sample thresh." and

adjust the Clr. thresh to 0.005.

Notes

• Leave all subdivs anywhere at their default values. They won't have any effect anyways - the 100 AA subdivs will almost certainly override everything else.
• For builds of VRay before 1.49.30, DO NOT use color mapping other than Linear. Otherwise, you risk to get an incorrect result in the end. If necessary, apply color correction in post. You can change the dark/bright multipliers, provided that you leave both at the same value.
• Avoid using sharpening AA filters. They can make the noise more apparent.
   
• Advantages of these settings:
  (*) Very little parameters for controlling render quality.
  (*) Work for a very large number of scenes.
  (*) Typically produce high-quality results.
   
• Disadvantages of these settings:
  (*) May be slow to render. With tweaking, you may get faster results.
   
• How it works:
  The high AA subdivs essentially causes all the sampling to be performed by the image sampler. It will take as many samples per pixel as required to achieve the specified noise threshold. In many ways, this is similar to PPT, but is done on a per-bucket basis and the number of samples is adaptive.
