3ds Max Vray Interior Lighting Tutorial

This page provides general guidelines for setting an interior scene for render.


This tutorial covers some general guidelines for rendering an interior scene.

First, we go through the default V-Ray render settings that are optimized for a large variety of scenes. With their help as a starting point, we
learn how to make quick render previews that can be used for light adjustments.
Then, we prepare the scene for a production render. At the end, we consider interior animation settings.

Still Image Render Settings

Step 1. First Render

1.1. Open the scene

1.2. Assign V-Ray as the current renderer.

 The default V-Ray settings generally work very well for still images. They require very little tweaking for most of the scenes and are a very good starting point.

1.3. Check the
Override mtloption in theGlobal switches rollout, click the button next to it, and select a default VRayMtl material. This way, you can mulai with a fast preview render.

1.4. Keep the resolution small (640×480) at this first step in order to save render time, while making changes to the scene.

1.5. Render the scene:

The first render is quite dark. Let’s see how to brighten it up, while aiming at a quick preview render.

Step 2: Quick Preview

2.1. Since the scene looks too dark, let’s brighten it a bit. There are several ways to do this. One is to increase the power of the lights. However, this will make the directly lit areas of the image, like the patch of sunlight, too bright, while indirectly lit regions will remain relatively dark. Once the materials are applied to the scene, it will brighten it up considerably.

2.2. In this case, you can make the override material brighter. Go to the Material Penyunting and put the default VRayMtl in one of the slots (it shows up as being used in the “Environment” in the Material/Maps browser).
Make the
color of the material RGB (200, 200, 200).

2.3. Let’s also explore the balance between noise and render time. For starters, set the
Render time
(min) to
0.0, that is, no limit in time.
This way V-Ray will continue rendering

until either the Noise threshold is reached or berayun-ayun the

Max. subdivs
are reached.
Now, let’s mulai with a high value
for the
Noise Threshold, something like


2.4. Render.

You still have the same amount of light entering the scene, but it is bounced around more and this increases the overall brightness of the scene.

At this point, you can adjust the ratio, color, etc of the lights, while getting a fast feedback on the lighting. The render is very quick, but the the image is grainy.

Step 3: Reducing Noise

3.1. To reduce the amount of noise in the image, let’s set the
Noise threshold

3.2. Re-render the scene.

The render time has increased (although it is still very fast), but the image remains noisy. This is a good trade-off for quick render previews.

3.3. Let’s try to lower the Noise threshold even more and see how this will affect the render time. We can try with two different values: 0.01 (the default V-Ray 6 value) and 0.005.

As a rule of thumb, decreasing the
Noise threshold
in half results in doubled render time. Be cautious with the amount of zeros after the point in the Noise threshold value!

Step 4:
Rendering with materials

4.1. Turn theOverride mtl
 option in theGlobal switches rolloutoff. 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 scene is ready for the final render.

Step 5. Final Adjustments for a Production Image

The default V-Ray settings work quite well for this interior scene.

5.1 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 1280×720 pixels.

5.3 Render.

The final render

Recommended Animation Settings

While the suggested settings work for most cases (bagian dalam, exterior, environments, pack shots, simulations), we suggest you to test them across a set of representative frames before committing to the final sequence rendering.

  1. Make sure you start with the
    default V-Ray render settings.
    You can reset them easily by changing the render engine to another and then changing it back to V-Ray 6.

2. Set the image sampler to Bucket. Go to
Render Setup>
tab >
Image sampler (Antialiasing)
Bucket. This is the preferred sampler type for final renders, as it’s marginally quicker than progressive, and works more comprehensively with a number of ancillary technologies.

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

To , see the difference between the default value of
in the

example above.

Notice that depending on a number of factors (scene type, lighting, shaders, geometry), the same noise threshold may produce


different results on a scene-by-scene basis. A good persen is to always test before committing to final.


For Light Cache, there’s an
preset that uses a
value of 8, as well as a
value of 3000, which is generally recommended in most cases.

5. Increasing the retrace value helps trace further rays where the Light Cache solution wouldn’t be good enough on its own.

6. The changes are all done. Test the values with a representative set of frames (ideally, the most complex ones), and if no issue is present, you can commit to the final render.


Should there still be optis artifacts within a single frame, raise the
Retrace value. In case you spot small changes to the GI solution across frames (“bubbling”), raise the number of LC subdivs. A value of
Retrace, and
for the Light Cache
should be the highest values you would ever need to go.
