This guide covers V-Ray’s key settings in SketchUp to produce high-quality renders efficiently. It assumes V-Ray 5+ (principles apply across recent versions). Follow the recommended defaults first, then tweak per scene complexity, lighting, and desired quality.

Brute Force + Light Cache (or Brute Force alone if using GPU). Light Cache Subdivs: 1000 to 1200 .

Under tab, click “Add” and include:

Open the V-Ray Asset Editor and click the gear icon to open the Settings tab. Your engine choice dictates how your computer processes the image.

The DMC (Deterministic Monte Carlo) sampler acts as the ceiling for all other subdivs settings. Many users ignore this, but it is the key to balanced rendering.

A critical workflow tip: Instead, leave them at 8 or 16 and control overall quality via the Noise Threshold and Max Subdivs in the Image Sampler. This is the "modern" V-Ray workflow, leading to faster, smarter renders.

To get the best results, you should configure your settings based on the project's stage: Render Engine for stability with complex geometry, or

Your output resolution is critical. A larger render is exponentially more demanding. As a rule of thumb, .

For a standard "full" render setting, use for the primary bounce and Light Cache for the secondary bounce. Here's the common "full render" setup:
