LESSON#6 – V-Ray settings and 5srw

  • Settings for low quality renders;
  • Settings for high quality renders;
  • How to save presets;
  • Critical parameters in the rendering time;

 

V-Ray settings and 5srw

Another interesting topic for the V-Ray users are the settings to get a “High Quality” render, however you have to understand the 5SRW concept, and what “High Quality” render means for us; When we talk about high quality renders we refer to clean renders, I mean, we are talking about the quality of the image but not the aesthetic, and I know that this may sound obvious but many people have the idea about a “secret” in the V-Ray configuration and they think that with this secret they can get a beautiful image, but this is only a technical issue, and it’s just one of the 5 steps; So, try by your self how with the 5SRW settings we avoid break our head with this technical issue and we will only focus on the artistic issue.

In the next video we gonna see 2 kinds of configurations, one will be for draft renders and the other for final renders.

  • Image Sampler.
  • Color Mapping.
  • Global Illumination.
  • Irradiance map + Light Cache.

Let’s go to the lesson:

 

[sc:videostreaming id=”7i782bwswhc8″ ]

CONCEPTS:

  • Use Adaptive Subdivision for draft renders;
  • For low quality renders use: Irradiance map on LOW and Light Cache on 200 subdivs;
  • Use Adaptive for High quality renders with Max subdivis on 40 and Color Threshold on 0.005;
  • For High quality renders use: Irradiance map on HIGH and Light Cache on 1500 subdivs;

 

5SRW SETTINGS vs CHAOSGROUP UNIVERSAL SETTINGS

I’m sure you heard about the universal settings of CHAOSGROUP, this has been changed with the time, and many improvements has been done since  V-Ray 3.2 version, and one of the most interesting is that Brute Force is faster, and because of this is becoming more useful, and some concepts like a primary and secondary rays has been discussed, however as you can see is not necesary break your mind with this concepts; In the next image you can see the image generated with the 5SRW settings and the below image with the Chaosgroup settings.

The difference between is:

Min Shade Rate on Image Sampler: 5SRW = (default value) CHAOSGROUP = 6

Max subdivis: 5SRW 40 CHAOSGROUP = 24

GI: 5SRW = Irradiance map + Light Cache CHAOSGROUP = Brute Force + Light Cache

5SRWvsChaos

As you can see the time difference is just 1min and there is a light improvement in the V-Ray Fur with the Chaosgroup settings, but is not important considering the aesthetic of the image; So it’s up to you use these configurations, however we recommend use the 5SRW to avoid confusion and follow our process.

EXERCISE:

Download the scene and make some test and practice until have clear the 5SRW configuration, after this, creates your presets and save it, with these you can save time each time that you open a new scene.
