V-Ray Tip: Quick Render Preview Preset Workflow to Accelerate Look‑Dev

Speed up look-dev by binding a low-cost preview preset to your Quick Render and switch back to your final preset only when needed.

• Create two render presets:
  • PREVIEW_Quick
    • Image sampler: Progressive. Set a relaxed Noise Threshold (0.08–0.12) and/or a short Time/Max Samples cap.
    • Resolution: 25–50% of final. Consider aspect-locked smaller sides for animation checks.
    • GI: Brute Force + Light Cache with lowered Light Cache samples, or temporarily disable secondary GI if the shot allows.
    • Denoiser: Enable NVIDIA (GPU) or Intel (CPU) in the VFB; set to Mild to stabilize previews without over-smoothing.
    • Turn off heavy hitters: Depth of Field, Motion Blur, Caustics, Volumetrics with high scatter steps, high-quality SSS layers.
    • Displacement: Use a larger Edge Length/lower Subdivs and consider “Keep continuity” off for speed (verify shading seams later).
    • Textures: Enable mip-mapping/filtered textures; use on-demand loading where available to reduce I/O spikes.
    • Masking: Use Render Mask (Selected/Include) or Region to focus on active areas.
  • FINAL_Base
    • Restore full resolution, target Noise Threshold (0.01–0.03 range), production GI, displacement quality, and required effects.
• Save and scope your presets:
  • Only include V-Ray settings that matter for iteration (sampler, GI, output size, denoiser, effects). Avoid unintentionally overriding camera exposure or AOV definitions.
  • Name presets clearly (e.g., “PREVIEW_Quick” and “FINAL_Base”) to prevent mix-ups during deadlines.
• Bind to Quick Render workflow:
  • Activate PREVIEW_Quick, tap Quick Render for rapid checks. Switch back to FINAL_Base only for sign-offs.
  • Use the VFB History for A/B comparisons; store a PREVIEW checkpoint and a FINAL checkpoint and toggle the Region Compare to scrutinize noise and detail where it matters.
  • Enable Render Stamp to log time, noise, and sample counts; this helps you quantify the speed/quality tradeoff.
• Extra accelerators:
  • LightMix in VFB: Lock lighting decisions from fast previews without re-rendering. Save presets for repeatable looks.
  • Cryptomatte and Material/Light Select elements: Keep them on even in previews so you can test post pipelines early.
  • For animation: Freeze Light Cache for camera flythroughs when previews stabilize; it prevents flicker while staying quick.
• What to watch for:
  • Do not judge micro-noise, glossy tails, or caustics from PREVIEW_Quick—confirm those in FINAL_Base.
  • If you downscale textures for previews, track it; mismatches can hide moiré or aliasing until late.

Adopting a disciplined Quick Render preset routine can cut iteration cycles dramatically while keeping final quality intact.
