vray 灯光和阴影（true 灯光和阴影）
Today, after a week of testing and continuous rearch, through the online query of the various parameters of the comparison, testing, and ultimately determine the next ideal business model, is now shared with you:
Key points: Reinhard 1.1/0.6, the default gamma value of 1,
Note: Reinhard is a way between the exposure index and intermediate linear balance, good u of both color contrast and saturation linear in place, and both light control ability index, so it is the focus of our application in the following pattern.
Test small graph parameters: (800*600) antialiasing: Adaptive Monte Carlo +Catmull-Rom (all parameters default),afl
Illumination map: very low, model subdivision, 30. interpolation, sampling 30, minimum square adaptation / overlap (very good / fast),
breakaway歌词Color mapping: Reinhard (Reinhard), 1.1/0.6/1.0
Global light: blue 2.5-3.0 (skylight parameters change size and color as needed)
RQMC sampling: 1, 0.02, minimum sampling 8:
Light buffer (subdivision) 200,
System: maximum tree depth: 80, dynamic memory limit 800
(single core 400/, dual core 800, and so on)
Big picture parameter (A41500*1050, A3, 2000*1500)
VR frame buffer is opened, the first three tick default, mainly to a convenient channel, but how specific channels, I also study, I prent goal is not the channel, only a small amount of PS, to achieve simple business objective.
Antialiasing: Adaptive Monte Carlo +Catmull-Rom (all parameters default),
Illumination map: medium, model subdivision, 60. interpolation, sampling 30, density bad (best),
Color mapping: Reinhard (Reinhard), 1.1/0.6/1.0
Global light: blue 2.5-3.0 (skylight parameters change size and color as needed)
iml
RQMC sampling: 0.85, 0.005, minimum sampling 12:
Light buffer (subdivision) 600,
System: maximum tree depth: 80, dynamic memory limit 800 (single core 400/, dual core 800, and so on)
recoveryI will upload to the venth top model. Thank you for your top posts!
Add: contrast% Reinhard and index, I feel in the Yin angle index
if the light a little stronger, Yin angle will have burnt, and Reinhard yadeizhu comparison in this respect.
Vray lights and shadows
Lighting parameters (detailed)
Vray lights
[open] turn on or off the VRay light.
[exclude] - exclude objects illuminated by light.
[type]
Plane - when this type of light source is lected, the VRay light source has a planar shape.
Sphere - when this type of light source is lected, the VRay light source is spherical.
Quaquaversal - when the source of this type is lected, the VRay light source is dome shaped, can model the effect of the sky
the tide is high[color] controls the color of the light emitted by the VRay light source.
[multiplier] - controls the intensity of the VRay light source
[Size size]
Half length - the U dimension of the light source (if the spherical light source is lected, the size is the radius of the sphere).
Half width - the V dimension of the light source (when choosing the spherical light source, the option
is invalid).
W size - the W dimension of the light source (when lecting the spherical light source, this option is invalid).
[double face] when the VRay light is a flat light source, this option controls whether the light is emitted from the two faces of the surface light source. This option is invalid when you lect the spherical light source
[invisible] - this tting controls whether the shape of the VRay light source body is displayed in the final rendering scene. When this option is turned on, the light is not visible and the VRay light source is turned off when the option is turned offhealthy是什么意思
To render with the color of the current light.
[ignore light normals] - when a traced light hits the light source, this option allows you to control the way VRay calculates light. For simulated real-world light, this option should
tugboat
When it is turned off, the render results are more smooth when the option is turned on.
[not fading) when this option is lected, the light generated by the VRay will not decay over distance. Otherwi,
The light will decay as the distance. (this is the way the real world lights are attenuated)
[storage light mapping) - when this option is checked and the global illumination is t to Irradiance map, VRay will calculate the effect of VrayLight again and store it in the light map. As a result, the calculation of the light map becomes slower, but the rendering time is reduced. You can also save the light map and u it later.
swimmer
[diffusion control] - controls whether light affects the diffu reflection of an object. It is usually open
[specular] - control whether the light affects the specular reflection of an object is usually turned ontrinacria
[value] this value controls VRay for calculating the number of sampling points for illumination. The larger the value, the finer the shadows, and the longer the render time.
VRay shadow
admit什么意思VRay supports surface shading, and VRay shadows are required when using VRay transparent refra
ction maps. At the same time, the blurred shadow generated by VRay shadow is faster than other types of shadow.
[transparent shadow] this option is uful when the shadow of
