4.1. Turn the Override mtl option in the Global switches rollout off. Leave the Noise threshold value to 0.01 here in order to preview the scene.
4.2. Render:.
Render time increases because V-Ray now goes through each material in the scene and samples it. There is some noise in the image, but overall the result is good.

The default V-Ray settings work quite well for this interior scene.
5.1. 1 The The only thing you need to do is to set the Noise threshold to 0.005 for even less visible noise.
5.2. For the final render, set the resolution to 1280x720 pixels.
5.3. Render.

V-Ray 6 solves those issues with only two tweaks to the default settings: Light Cache Subdivs, and Retrace amount. While the suggested settings work for most cases (interior, exterior, environments, pack shots, simulations), we suggest you to test them across a set of representative frames before committing to the final sequence rendering.

3. Choose the Noise Threshold that best suits your needs. A value of 0.005 gets rid of visible noise without the need of post-render denoising. To compare the two, see the difference between the default value of 0.01 and 0.005 in the example above.

Notice that depending on a number of factors (scene type, lighting, shaders, geometry), the same noise threshold may produce marginally different results on a scene-by-scene basis. A good tip is to always test before committing to final. |
4. Increasing Light Cache Subdivs ensures that the Light Cache is well sampled, and stable across frames. The impact on render time of the higher subdivs is negligible compared to the rendering of the actual frame, so this is a good general practice without any particular drawbacks.
