Unity3d Game Development 3DMAX Lighting
Welcome to Unity Learning, unity training, Unity Enterprise Training Education Zone, there are many u3d resources, u3d training videos, u3d tutorials, u3d FAQs, u3d Project source code, "Dog Planing Learning Network" Unity's Ultimate Academy, dedicated to building the industry Unity3d training, learning the first brand.
One, 3DMAX five kinds of light source
1. Ommi Light floodlight: A point light that can be evenly illuminated from one point to the other.
2. Target Spotlight Spotlight: A projecting beam that affects the irradiated object within the beam, which can be projected
Shadow, the irradiation range can be specified.
3. Free Spotlight Spotlight: A spotlight without a projected target, usually on a motion path, or with its
Shadow, the irradiation range can be specified.
4. Target directional Lights directional light: a light that emits a parallel beam, typically used to simulate
sunlight, and can specify the motion of the target point.
5, free directional Lights Freedom Direction light: Divergent parallel beam, but no target point can be adjusted.
second, produce the projection effect
1, with Ommi flood light projection effect: Gast Shadows projection Options
2. Target Spotlights Spotlight: The blur and clarity of spotlight projection edges is determined by the quality of the light and the angle of illumination
, the middle bright area is called the spotlight, and the transition region of the periphery and edge is called the falloff area. And the intensity of the light can manifest itself.
on the hotspot and attenuation areas, the spot and the Falloff area are the same size, which produces sharp beam edges.
(1) Create a projected image with target spotlights spotlight: Projector map mapping Map None
button, adjust the hotspot parameter, cast Shadows tick to open the shadow setting, resulting in a cast shadow. In Shadow
in the Parameters project panel, select Ray traced Shadows to Ray-traced from the shadow MAP drop-down menu. Size
The parameter controls the resolution of the Shadow map, which adjusts the value accordingly, depending on the diameter of the falloff area. SMP Range Sampling Range: determines the winding
How many pixels are sampled on the edge of the shadow, the smaller the pixel is, the sharper the edge of the shadow.
(2) Square Spotlight: Spotlight Parameters Project Midpoint rectangle Square, adjust ASP
the parameter (length-to-width ratio) is 1.8. Overshoot: It illuminates the entire scene like a flood, and still produces in the projected range
Shadow projection. (on off, the lighting effect disappears in the view)
(3) to exclude objects from light effects: Exclude: Excludes objects from the specified spotlight.
(4) light switch and hide " Dog planing Learning Network Unity3d Extreme Academy "
Binding Line
(5) Light attenuation setting: light has a brightness attenuation characteristics, it will be based on the distance from the light, slowly
reduces the brightness of the light. Attenuation Parameters attenuation parameter, the light starts to decay from the yellow range line until the brown edge
The line is completely attenuated and there will be no more light outside the brown border.
(6) Negative light effect: Multiplier can increase the density and intensity of light. A preset value of 1, if greater than 1
can result in overexposure. Less than 0 o'clock, it produces a negative light effect that absorbs light and uses it to weaken areas where the light is too strong.
This is real life in the absence of light.
(7) Transparent Shadow effect: casts a transparent shadow from a transparent object.
(8) Patterned transparent shading: Click the small Fang on the right side of the filter blue button in the extended Parameters extension parameter item in the material editor.
