Solar parameters of virtual reality

Control the cleanliness of the air, with a value of 2-20? Suddenly, the larger the value, the greater the interference of the sun, which is warm yellow or red, and the smaller it is, the cleaner it is, which is blue. Generally 3-5 noon, 6-9 afternoon and evening 15.

2. Ozone:

Set the thickness of the ozone layer. The larger the value, the thinner the ozone layer, the lower the intensity of sunlight and the weaker the light diffusion. Valid values are 0- 1.

3. Intensity multiplier:

Set the sunlight intensity to match the turbidity. The greater the turbidity, the warmer and darker the sunlight. If you use Vray? Physical camera, generally 1? About, if you use 3DS? Bring your own camera, usually 0.002-0.005? .

4. Size multiplier:

The greater the light, the more scattered the shadows will be, generally 3-6 are appropriate.

5. Shadow subdivision:

The smaller the shadow, the worse the shadow quality. The larger the size multiplier, the greater the subdivision value, generally 6- 15? .

Extended data

1. Shadow offset parameter:

The larger the value, the farther the offset distance. Generally keep the default.

2. Photon emission radius parameters:

The larger the (1), the larger the irradiation range. Used in combination with photon mapping. When the sunlight intensity is greater than the sunlight, the skylight is dominant, and the cool color is the main effect.

(2) When the light intensity of the day is less than the sunlight, the sunlight is dominant and the warm color is dominant. At the same time, if the skylight is properly reduced, the turbidity of sunlight can get the effect of cold tone, while if the skylight is properly increased, the turbidity of sunlight can get the effect of warm tone.

(3) In general, we only need to adjust turbidity and intensity-multiplier? The angle between the sum of these two values and the plane controls VRaySun? Color and brightness, other values cannot be changed.
