How can we solve the problem that the ground overlaps the infinite plane and causes more noise on the ground?

1.Increase the anti-aliasing parameters:

Minimum ratio: The number of times in which the noise is small, is fused. When the contrast of the light and shade of an image is obvious, black places are especially dark. When the bright places are especially bright, the minimum ratio should be used in small numbers. The maximum ratio uses large numbers.

Maximum ratio: Control the quality effect. The bigger the value, the more times the noise is calculated, the slower the speed.

Sketching animation: Minimum ratio -1，Maximum ratio 1

Commercial high definition building animation：Minimum ratio 3，Maximum ratio 4

Commercial high definition jeweler animation：Minimum ratio，Maximum ratio 8

2. Reduce the noise threshold:

Noise Threshold：The smaller the value, the more the sample, the less the noise, the better the effect. The default is 0.01.

3. Increase the subdivision of light

If there's noise in the whole picture, increase the light subdivision.

Luminescent map, the minimum ratio is selected to -3 or -2 while the Maximum ratio is -1 or 0.

Light caching, adjust the subdivision to 1000~1200.

4. Too low of material gloss sets will cause more noise.

Glossiness is the rendering of fuzzy reflection, the smaller the value, the more blurred, and the more noise it shows.

Example: The problem:

Reason: The high gloss and reflection values of some materials are too low.

Resolvent: The minimum of high light and reflection is 0.8.

5. Reduce the sensitivity and shutter speed

Reduce the camera's sensitivity and shutter speed, and then add the brightness of the skylight or light. This is to make up for the light sense of the camera.
