The Image Sampler controls how smoothly curves and sharp edges are rendered.
GI calculates how light bounces around your scene. This is the most critical tab for realistic lighting.
If your render is still slow, check your Hardware Recommendations ; V-Ray often requires at least double your GPU VRAM in system RAM for smooth performance. vray render settings for sketchup full
: Lower values let in more light; higher values make the image darker. Interior Scenes : Set EV between 10.0 and 12.0 . Exterior Scenes : Set EV between 13.5 and 15.0 .
Recommended for final renders; it processes the image in square "buckets" for maximum precision. The Image Sampler controls how smoothly curves and
Set to 800–1000 for quick previews. Increase to 1500–2000 for clean, high-quality final interior renders. 3. Image Sampler and Noise Control
Before diving into the numbers, you must decide how the image will be calculated. If your render is still slow, check your
| Problem | Cause | Solution | |---------|-------|----------| | | Low Max Subdivs or Noise Limit too high | Increase Max Subdivs to 24, Noise Limit to 0.005 | | Fireflies (white dots) | Specular highlights | Enable “Clamp Output” (10.0) + increase LC Subdivs | | Black spots on glass | Refraction depth too low | Set Refraction Max Depth to 8+ | | Render too dark | Low exposure or missing GI | Check Environment map intensity (set to 1.0) | | Long render times | Unnecessary geometry | Use V-Ray Proxy for trees/cars |
Global Illumination calculates how light bounces off surfaces, which is the secret to photorealism.
