Adjusting VRay 2.0+ Settings for Interiors

Advertisements

VRay Settings are crucial in producing an awesome scene.

Hey designers, Looking for a way to get the best renders? You’ve come to the right place.

With the title in mind, this tutorial about adjusting VRay Settings aka ‘the Options menu values’.

If you ever wandered through that menu, you will find that all options are adjustable numerically, hence the ‘values’.
Not to bore you with details; in short, these options are responsible for the way your work is rendered (Details, shadow, light, brightness, etc.).

Note that I am using VRay 2.4 for SketchUp, other versions may vary a little bit, but not entirely different.

The Default Options in VRay for SketchUp are set up so that certain elements of VRay are already good to go. This is great because certain aspects that are specific to VRay are already configured with the proper settings. Other values are adjusted according to version, machine model, graphics card, and personal preference.

For VRay Light Settings you can go Here.

The most important thing when rendering are the options associated with Light and How Light Reacts and Bounces off Certain Objects and Materials, like Indirect Illumination, Irradiance Map, Camera, Environment, and Light Cache. You’ll need to pay extra attention to those.

For adding a VRay Sky you can go Here.

Now that we are acquainted with the technical jargon associated with Options, let me show you how to tweak those to your benefit, plus a few extras!

 

If you’re a newbie, here’s where you will find the Options window:

 

Let’s start with Global Switches tab, going downward, modify the values as shown in the pictures:

From ‘Environment’ click the ‘m’ in ‘GI(skylight) to open the window in next picture

mimic these settings from ‘GI(skylight)’ to ‘Reflection/refraction (background)’

---

After applying those settings make sure you press the Save Icon at the top of the window, and give your settings a name, then save them in an easily accessed place (You will need to load them every time you start a new project).

A little thing to keep in mind when choosing or changing your output quality Irradiance Map samples need to change too; since Irradiance Map is directly linked with how many pixels are there in an image. This will make sure that your render comes out as accurate as possible.

 

These are the values corresponding to VRay’s default image sizes for ‘Irradiance Map’:

• 800×600:
  • Min/Max: -3/1
• 1600×1200:
  • Min/Max: -5/-2
• 3200×2400:
  • Min/Max: -6/-3
• 6400×4800:
  • Min/Max: -7/-4

One more thing to know about Irradiance Map is that the smaller the values in Min/Max, the higher the quality of the render, and the slower it gets. The higher the values of the Min/Max, the lower the quality of the render, and the faster it gets.

But, the values above should be fine for you, it gives me good quality at a reasonable render time, so it should do that for you too.

When it’s time to render a new project, load these setting by clicking Load:

Then finding the file you saved and clicking Open:

You’re ready to go!

Let me show you the type of result you will get when using these options.

 

To Create Your Own Material you can try THIS.

In this picture I used these materials, to show the render at its best:

• Wood (Grainy Surface)
• Metal (Polished Surface)
• Glass (Translucent)
• Stone (Rough texture)
• Plastic (Glossy Surface)
• Ceramic (Mirror Surface)
• Enamel (Shiney Surface)
• Fabric (Soft Texture)

I also used (Shadow Settings) November and Noon sunlight (Gives a “It’s about to rain/It just Rained” light) and no artificial lights.

With no further delay here are the render results:

• A couple of close ups to the materials for details:

By the way, the picture used at the top of this post was rendered using those settings.

 

Hope this helped, and don’t hesitate to comment with a question or a suggestion!
