Don't punch in numbers every time.
Do not rely solely on the presets (Low to Ultra). Manual tuning yields better results.
The General Settings section is where you'll configure the basic parameters for your render. Key settings include:
Never try to eliminate 100% of noise using Sampler settings alone; it wastes hardware power. Instead, enable the . Set the denoiser to Default or Mild .
| Problem | Why it happens | "Full" Fix | | :--- | :--- | :--- | | | Specular highlight on a thin edge | Turn on Subpixel Mapping and Clamp Output to 5. | | Black splotches on ceiling | Irradiance map too low | Switch to Brute Force as Primary GI. | | Blurry shadows | Light Cache Sample size too high | Reduce Sample Size to 0.015 . | | Glass looks black | Ray Depth is too shallow | Set Max Depth (Refract) to 24 . | | Render stuck at "Building Light Cache" | Too many emissive materials | Replace emissive with actual rectangle lights. |
The "Full" settings allow you to switch between (Infinite passes, good for tests) and Bucket (Tile-based, excellent for final renders and distributed rendering).
Accessed via the , these settings define how V-Ray processes your scene.
Lower this value (e.g., 0.005 ) for a cleaner, sharper image.
