For quick tests, use Draft or Medium . For final high-resolution images, move the slider to High or High+ . 2. Camera & Exposure Control
Complete Guide to V-Ray Render Settings for SketchUp Achieving photorealistic results in V-Ray for SketchUp requires a balance between render quality and processing time. This guide breaks down the essential settings in the V-Ray Asset Editor to help you optimize your workflow for both quick drafts and final, high-resolution presentations. 1. Core Render Engines: CPU vs. GPU
| Problem | Probable Cause | Fix | | :--- | :--- | :--- | | | Extremely bright glossy reflection (e.g., chrome near sun) | Lower Max ray intensity in Settings > DMC to 10 or 5 | | Blotchy walls | Irradiance Map too low | Increase IM preset to High or switch Primary to Brute Force | | Grainy shadows | Light subdivs too low | Select light > Increase Subdivs from 8 to 24 | | Render freezing | Not enough RAM (likely heavy proxy or high-poly tree) | Reduce texture resolution to 1024x1024; Turn off "Render mask" | | Too dark | Physical Camera exposure on, no light | Turn off Exposure temporarily; Add dome light with HDRI | vray render settings for sketchup
: Good balance for checking material textures and secondary lighting details.
Controls how V-Ray samples each pixel to smooth jagged edges. For quick tests, use Draft or Medium
Match your camera composition. Use 16:9 Widescreen for landscape views, or 1:1 Square / 4:5 Vertical for social media presentations. Image Resolution:
☐ Set Noise Threshold to 0.005 or lower. ☐ Light Cache Subdivs at least 2000 . ☐ Denoiser ON (unless you prefer raw output). ☐ Save image format: (for post) or PNG (for sharing). ☐ Disable any material override. ☐ Render region cleared. Camera & Exposure Control Complete Guide to V-Ray
Here’s a clear, practical write-up on , suitable for a blog post, tutorial, or client guide.
Use the VFB for post-processing (like exposure and hue adjustments) immediately after rendering so you don't have to re-render to fix minor lighting issues.
| Problem | Likely Cause | Fix | | :--- | :--- | :--- | | Grainy, even after long render | Noise Threshold too high | Reduce to 0.005 or 0.01 | | Splotchy shadows on walls | Light Cache Subdivs too low | Increase to 1500 + | | Very long render times | Max Subdivs unnecessarily high (e.g., 200) | Reduce to 64 for final | | Too dark / blown out | Color Mapping Exposure | Adjust Exposure value (try 1.2–2.0) | | Noisy reflections | Low Image Sampler Max Subdivs | Increase to 32 or 48 |
