Backface Culling – Відкидання Тилу¶
Backface Culling hides the back side of faces in the final render.
Blend Mode – Режим Змішання¶
After calculating the color of a surface, the blend mode defines how it is added to the color buffer. Depending on this, the final color will be different.
Примітка
Alpha Blending вважається режимом змішання «Transparent» та має наслідки стосовно ефектів простору екрана.
- Opaque – Безпрозоре
The previous color will be overwritten by the surface color. The alpha component is ignored. This is the fastest option.
- Alpha Clip – Відсік Альфа
The previous color will be overwritten by the surface color, but only if the alpha value is above the clip threshold.
- Альфа Кришено – Alpha Hashed
The previous color will be overwritten by the surface color, but only if the alpha value is above a random clip threshold. This statistical approach is noisy but is able to approximate alpha blending without any sorting problem. Increasing the sample count in the render settings will reduce the resulting noise.
- Змішування Альфа – Alpha Blending
Використовується змішування альфа для накладу кольору поверхні поверх попереднього кольору.
Проблема Сортування – Sorting Problem¶
When writing to the color buffer using transparent blend modes, the order in which the color blending happens is important as it can change the final output color. As of now Eevee does not support per-fragment (pixel) sorting or per-triangle sorting. Only per-object sorting is available and is automatically done on all transparent surfaces based on object origin.
Примітка
This per-object sorting has already a cost and having thousands of these objects in a scene will greatly degrade performance.
- Show Backside
If enabled, all transparent fragments will be rendered. If disabled, only the front-most surface fragments will be rendered. Disable this option to ensure correct appearance of transparency from any point of view. Then using Alpha Blending this option should be disabled because with Alpha Blending, the order in which triangles are sorted is important.
Shadow Mode¶
Type of shadows used for a transparent surface. Eevee does not support colored shadow maps.
Напівпрозорі тіні можуть продукуватися шляхом використовування кришених прозорих тіней та більшого значення Soft для розкладки тіней.
Примітка
This option does not change the behavior of contact shadows which are traced using the depth buffer. If the material is writing to the depth buffer (in other words, if the blend mode is set to either Opaque, Alpha Clip or Alpha Hashed), contact shadows will be casted by the surface material regardless of the Transparent Shadow type.
- None – Нема
Поверхня не буде відкидати будь-які тіні.
- Opaque – Безпрозоре
Поверхня буде відкидати тіні, як безпрозора поверхня.
- Clip – Кліп
The surface will cast shadows like an opaque surface, but only areas where the alpha value is above the clip threshold.
- Hashed
Поверхня буде відкидати тіні, як безпрозора поверхня, але лише в областях, де значення альфа є вище випадкового порогу.
Заломлення Простору Екрана – Screen Space Refraction¶
Enabling Screen Space Refraction on a surface means that refraction BSDFs will do a ray trace against the depth buffer to find the most accurate refracted color. This has a big performance cost if the surface covers a lot of pixels.
Screen Space Reflections and Ambient Occlusion are not compatible with Screen Space Refraction. They will be disabled on the surfaces that use it. Surfaces that use Screen Space Refraction will not appear in Screen Space Reflections at the right place. Surfaces that use Screen Space Refraction will not cast Ambient Occlusion onto other surfaces.
If this option is disabled or if the Screen Space Refraction ray tracing fails, the refracted ray will use the color of the nearest probe.
- Заломлення Простору Екрана – Screen Space Refraction
Вмикає заломлення простору екрана.
- Глибина Заломлення – Refraction Depth
If Refraction Depth is not 0.0, all refraction BSDFs in the shader will act as if the object is a thin slab of the refraction material having this thickness. This will model a second refraction event that will double the absorption color and start the refraction ray after this second event.
Ця опція значно збільшує якість тонких скляних об’єктів.
Півпрозорість Підповерхні – Subsurface Translucency¶
Eevee’s Subsurface Scattering algorithm works by blurring the irradiance in screen space. This means that if no visible part of the surface is lit, the effect disappears.
However, true Subsurface Scattering goes beneath the surface and can travel a large distance. This is why a human ear lit from behind appears red on the front side.
That is what this effect mimics. This translucency approximation only works with lights that have shadow maps and only on Subsurface BSDFs (not the Translucency BSDFs). It does not work with indirect lighting. The soft parameter of the shadow maps also affects this effect.
Індекс Проходу – Pass Index¶
Index number for the Material Index render pass. This can be used to give a mask to a material which then can be read with the ID Mask Node in the Compositor.
