Remark: to make Vray online licnese works, the step below is needed:

Installing Chaos Group License Server:


Main factors:
Brute Force,
Light Cache,
Denoiser,
Progressive Image Sampler

For low resolution setting for best render:


In Render Setting,
Render Element → Add Denoiser
GI → Secondary bounces, Engine → Light Cache
→ Subdivs 500]
Vray → Image Sampler → Progressive → Noise Threshold: 0; max render time 1-3min

For high resolution setting for best render:


Preset → import render setting → default setting

Preset: Animation (if the output is not a still image)
Vray → Image Sampler → Noise Threshold 0.005 (mean render stops when the noise level reach downs to 0.005) , max time 0 mins (means no limit of max render time) Such setting may need render 14mins per image

Remark:


1.Vray quick Setting box is removed in Vray 5, and GI is turn on by default.
2. To reduce highlight part over expose/burn area, go to Vray tab in render setting →
Color mapping → Type: HSV exponential, OR type keep as Reinhard, but burn value goes down (have to render again if changing the highlight burn
Better solution:
In Vray frame buffer box, click add layer icon → Exposure → its properties bump up (bottom R corner) → Exposure→ reduce Highlight burn value and check the instant result in the buffer box
