라이트맵 파라미터
미리 계산된 조명 사용

인라이튼을 사용한 라이트매핑(지원 중단 예정)

*인라이튼은 지원이 중단되어 곧 제거될 예정입니다. 자세한 내용은 Unity 블로그를 참조하십시오. 또는 프로그레시브 GPU 라이트매퍼(프리뷰) 또는 프로그레시브 CPU 라이트매퍼를 사용할 수도 있습니다.

Unity의 인라이튼 라이트매퍼는 미리 계산된 실시간 GI에 기반하여 간접 조명을 생성합니다. 이렇게 하면 조명을 변경할 때 새로운 라이트맵이 매우 빠르게 생성되는 이점이 있습니다. 하지만 베이크된 조명에만 사용하고 싶은 경우에도 UV 레이아웃 제한이 적용되는 점은 프로그레시브 라이트매핑과 비교하여 단점이 될 수 있습니다.

인라이튼 라이트매퍼를 사용하려면 Window > Rendering > Lighting Settings 에서 Lightmapping Settings 로 이동한 후 LightmapperEnlighten 으로 설정하십시오.

Property: Function:
Lightmapper Use this to specify which internal lighting calculation software to use to calculate lightmaps in the Scene. The options are:

Progressive CPU
Progressive GPU
Enlighten (deprecated)

The default value is Progressive CPU.
Final Gather Final Gather is only available if Lightmapper is set to Enlighten.

Enable this if you want the lightmapper to calculate the final light bounce of the global illumination at the same resolution as the baked lightmap. This improves visual quality, but requires additional time to bake the lighting.
Ray Count Specify the number of rays the lightmapper emits for every final gather point.
Denoising Enable this to add a denoising filter to the final gather output.
Indirect Resolution Use this to specify the number of samples the lightmapper uses for indirect lighting calculations. Higher values can improve the quality of the lightmaps, but increase the time it takes to bake them.
Lightmap Resolution Use this to specify the number of texels per unit to use for lightmaps. Increasing this value improves lightmap quality, but also increases bake times. Note that doubling this value causes the number of texels to quadruple (because the value refers to both the height and width of the lightmap).
Lightmap Padding Use this to specify the separation (in texel units) between separate shapes in the baked lightmap. The default value is 2.
Lightmap Size The size (in pixels) of the full lightmap texture, which incorporates separate regions for the individual GameObject textures. The default value is 1024.
Compress Lightmaps A compressed lightmap requires less storage space, but the compression process can introduce unwanted visual effects into the texture. Tick this checkbox to compress lightmaps, or untick it to keep them uncompressed. The checkbox is ticked by default.
Ambient Occlusion Tick this checkbox to open a group of settings which allow you to control the relative brightness of surfaces in ambient occlusion. Higher values indicate a greater contrast between the occluded and fully lit areas. This only applies to the indirect lighting calculated by the GI system. This setting is enabled by default.
Max Distance Set a value to control how far the lighting system casts rays in order to determine whether or not to apply occlusion to an object. A larger value produces longer rays and contributes more shadows to the lightmap, while a smaller value produces shorter rays that contribute shadows only when objects are very close to one another. A value of 0 casts an infinitely long ray that has no maximum distance. The default value is 1.
Indirect Contribution Use the slider to scale the brightness of indirect light as seen in the final lightmap (that is, ambient light, or light bounced and emitted from objects) from a value between 0 and 10. The default value is 1. Values less than 1 reduce the intensity, while values greater than 1 increase it.
Direct Contribution Use the slider to scale the brightness of direct light from a value between 0 and 10. The default value is 0. The higher this value is, the greater the contrast applied to the direct lighting.
Directional Mode You can set the lightmap up to store information about the dominant incoming light at each point on the objects’ surfaces. See documentation on Directional Lightmapping for further details. The default mode is Directional.
Directional In Directional mode, Unity generates a second lightmap to store the dominant direction of incoming light. This allows diffuse normal mapped materials to work with the GI. Directional mode requires about twice as much storage space for the additional lightmap data. Directional lightmaps cannot be decoded on SM2.0 hardware or when using GLES2.0. They fall back to Non-Directional lightmaps.
Non-directional Non-directional mode disables Unity’s ability to generate a second lightmap to store the dominant direction of incoming light.
Indirect Intensity Use this slider to control the brightness of indirect light stored in realtime and baked lightmaps, from a value between 0 and 5. A value above 1 increases the intensity of indirect light while a value of less that 1 reduces indirect light intensity. The default value is 1.
Albedo Boost Use this slider to control the amount of light Unity bounces between surfaces, from a value between 1 and 10. To do this, Unity intensifies the albedo of materials in the Scene. Increasing this draws the albedo value towards white for indirect light computation. The default value of 1 is physically accurate.
Lightmap Parameters Unity uses a set of general parameters for the lightmapping in addition to properties of the Lighting window. A few defaults are available from the menu for this property but you can also create your own lightmap parameter file using the Create New option. See the Lightmap Parameters page for further details. The default value is Default-Medium.
