Vray Settings

In this Vray quick tip video, learn how to adjust the size and quality of your renderings in Vray!

In this video, I just wanted to give a quick run-through on how to adjust the resolution and size of your renderings in Vray for SketchUp, as well as your quality settings.

The V-Ray settings dialogue box uses tabs that expand and contract keeping the settings a little more manageable to navigate. An important button to be familiar with is the “Load Defaults” button. This will take everything to the default V-Ray settings when the program was first installed.

When you’re working with renderings, you don’t want to do your test renders on super high setting, super high resolution images – the larger your image, and the higher your settings, the longer your rendering is going to take.
This is a model from a tutorial I did on my other channel, the SketchUp Essentials, teaching you how to use HDRI images for lighting and backgrounds within your models.
All of the options we’re going to change are located within the settings tab of the Vray asset editor.

In this part I will show you how to use V-ray light materials and some general tips for baking v-ray dirt and using opacity maps. Top 5 Vray Workshop - the best works of last week Vray Workshop + Evermotion present TOP 5 VRay Workshop - selection of the best works presented during the week.

An advanced guide to the interior rendering of still images within Chaos Group Vray and Autodesk 3ds Max. Most will argue that there are no “universal settings” for Vray and I tend to agree. But there are steps you can take in order to get close to what you need for the majority of interior visualisation.

Vray Resolution Options

First of all, let’s take a look at our resolution options. Click on the gear to get into your render settings – If you look down, there’s a little arrow for render output. Within this section, you can adjust the resolution and aspect ratio of your rendering.
The safe frame is going to indicate which part of your viewport will be displayed when you run your rendering – it basically shows you which part of your image will get rendered with your currently selected aspect ratio.
You can adjust the size of your image by adjusting the values within the image width/height section – note that these values will get locked to a certain Aspect ratio based on whichever ratio you have selected.
Note that you can make these values smaller for a faster render, and larger for a slower, more detailed render.

Vray Rendering Quality Settings

Now let’s take a look at the quality settings. To do this, go up to the dropdown labeled “Renderer.”

Note that depending on if you have an interactive render or a regular render selected, your quality options might not show up. These options only show up if you have a regular render selected.
Once you select a regular render, the option for quality will show up. You can adjust the bar from left to right to select quality levels ranging from Draft, which is very fast and creates a
very noisy image, all the way to very high, which will take much longer but will generate a more detailed image.

You can adjust these settings to create faster test renders, then turn the settings up when you’re ready to create your final render!

Exterior Render Settings V-Ray and SketchUp

Vray Settings For Sketchup

In order to fully understand the possible render output in V-Ray using various environment settings such as V-Ray Sun and Sky, Domelight+ HDRI and V-Ray Environment + HDRI, I made a simple rendering experimentation that highlights different parameters or settings which generally affect the tonality and atmosphere of the rendered image output.

During the test render experimentation, I enabled the material override and set the water pool to “Can be Overridden” . I also added a Sphere model inside the scene with silver polished material in order to see the reflection of the sky.

For V-Ray Sun and Sky System, I set up a basic scene in default setting and lit it a couple of different ways, (enabling and disabling) V-Ray sun, background, and GI (Skylight). For V-Ray dome light with HDRI texture, a comparison test render was made using default setting and optimized setting. For V-Ray Environment with HDRI texture, the test render will highlight the possible output when render in optimized setting using HDRI as the light source and V-Ray sun as an additional light source.

GENERAL SET-UP

1. V-Ray Sun and Sky System

Vray Settings 3ds Max

In V-Ray default setting, V-Ray Sun and V-Ray Sky are special features which are provided by the V-Ray Renderer. When set in default setting, notice the sunlight is enabled. If you go to V-Ray Asset Editor> Settings> Environment> Background, you can see that the default background is set to V-Ray Sky or technically the V-Ray Sun (V-Ray sunlight). Under Environment Overrides, the GI Skylight is technically turned off in default settings. However, when you turn on the GI Skylight option and choose the V-Ray sky as the light source, the render result will be similar to V-Ray default settings. In comparison to Dome light and V-Ray Environment settings, the shadow appeared to be sharper when rendered using V-Ray Sun and sky system.

1.0 V-Ray Sun

Settings 1.1 (default) and 1.2 show a similar render output, producing such clearer environment. Here, enabling the GI skylight with V-Ray sky as the light source does not affect the output when the V-Ray sun is turned on.

This atmosphere goes the same in Setting 1.9 with a slight difference in terms of the background.

Settings 1.3 and 1.4 show a similar render output. Enabling the GI skylight with V-Ray Sky as the light source while the V-Ray sun is turned off doesn’t produce such brighter environment. Here, the light power using GI skylight with V-Ray sky as the light source does not produce a brighter environment as compared to the V-Ray sun when turned on. The V-Ray sky as the background image enable to illuminate in the material of the 3-D object.

Setting 1.7 produce almost the same atmosphere similar to settings 1.3 and 1.4 but with different background.

Setting 1.5 shows that turning off the V-Ray sun and GI sky light (which means there is no any light source) makes the model illuminate to darker environment while the background is still visible when turned on.

Setting 1.6 shows that when using both V-Ray sun and GI skylight with no light source (None) the environment becomes warmer, cloudy or hazy.

This atmosphere goes the same in Setting 1.8 with a slight difference in terms of the background.

Setting 1.10 shows that increasing the value of GI skylight with V-Ray sky as the light source while the V-Ray sun is disabled produce a brighter illumination of materials.

2. Dome light+ HDRI

Using V-Ray for SketchUp, when loading a Dome light+ HDRI in default setting, the render result will be darker in nature (See image 2.0/ Setting 2.1.A). Thus, optimizing the Dome light settings is important in order to produce a suitable environment in relation to HDRI map. (See image 2.0/ Setting 2.1.B). In order to set-up the Dome light: click the Dome light icon and place it in your SketchUp scene. To change the parameters for Dome light follow the procedures: under ‘V-Ray Asset Editor’> go to ‘Lights’> click the V-Ray Dome light> under Light dome, you can see two main parameters (Main and Options). Follow the parameters set-up I made for this test render experiment (See image 2.1 Dome light Setting). The shadow in Dome light+ HDRI set-up appears to be smoother than V-Ray sun setting. This can be illustrated in test render sample (see image 2.0/ Setting 2.1.B and Setting 2.2.B). Using Dome light set-up, the lights come from HDRI map as direct light, and all effects like shadows, reflection, etc… will be apparent.

2.1 Dome light settings

In Dome light, adjusting the intensity will generally affect both the background and the light at the same time. The advantage of using V-Ray Environment than Dome light is that you can use different maps for both lighting and background while at the same time, adjusting the intensity separately by multipliers. Optimizing the V-Ray Environment is important in order to produce a suitable environment to your scene. Enabling V-Ray sun while GI skylight is turned on (optimized) is not necessary, since you don’t need to have two light source in your scene. Having two light source in one scene will just increase the render time.

PARAMETERS:

1. V-Ray Sun (Default setting)

V-Ray Sun and Sky system, ensure a faster render than Dome light and V-Ray Environment. This render setting is the very basic of V-Ray Sun Environment.

5.1.1 V-Ray Sun (settings)

2. Dome light+ HDRI
The V-Ray Dome light is a really quick way to get clean results if you can’t use irradiance maps which is typical in V-Ray Environment setting. The V-Ray dome light does the importance sampling which gives you a better shadows, quicker and cleaner render than V-Ray Environment.

5.2.1 Dome Light HDRI (settings)

3. V-Ray Environment + HDRI

On the other hand, V-Ray Environment set-up offers a more flexible option as compare to Dome light setting. Here you can adjust the intensity of the light source and the visibility of the background (both in HDRI map) separately using multiplier. Although, this is a more tedious work as compare to Dome light set-up from which the intensity of the light source and background can be adjusted all at once, I prefer this set-up because you have the liberty to adjust the background and the light source separately, based on your preferred settings.
