That is why you avoid using them unless absolutely needed.Īll you need to know is NEVER check and use local subdivs. 99% of the time the source of noise is going to be a self-illuminated texture. Instead, find the culprit for the noise in your scene. 008 can increase render times as much as 20% or more. Be careful turning this down to fix a noisy render because reducing this value, even down to. Noise Threshold controls-wait for it-noise.01 is generally fine for most scenes. Min Subdivs of 1 and Max Subdivs of 24 are more than good enough for renderings up to 4K. This is where you control the anti aliasing and noise of your renders. In the V Ray tab, switch the Image Sampler to "Bucket." The "Progressive" image sampler is the un biased engine, which is not what you want.
V Ray has become much smarter over the years, but unfortunately the documentation has not kept pace and much of what you read online is no longer correct.įor instance, there is no need to pre calculate anything before sending a render to a farm (the only caveat is all machines must have the same motherboard and use the same versions of VRay, Max and Backburner.)
