Surface (поверхность)
- Displacement Method
Method used to perform Displacement on materials.
- Displacement Only:
Вершины полисетки перед её визуализацией будут смещены, таким образом изменяя текущую полисетку. Лучшие результаты получаются, если полисетка уже сильно подразделена. В результате этот метод так же очень сильно использует память.
- Bump Only:
When executing the surface shader, a modified surface normal is used instead of the true normal. This is a less memory intensive alternative to actual displacement, but only an approximation. Surface silhouettes will not be accurate and there will be no self-shadowing of the displacement.
- Displacement and Bump:
Оба метода могут быть скомбинированы, чтобы добавить истинное смещение на грубую полисетку, а затем использовать рельефное текстурирование для добавления деталей.
- Emission Sampling
The method used for sampling the emissive component of the material. This option will only have an influence if the material contains an emissive material node, otherwise it will be ignored.
- None:
Do not use this surface as a light for sampling.
- Auto:
Automatically determine if the surface should be treated as a light for sampling based on emission intensity.
- Спереди:
Treat only the front side of the surface as a light, useful for closed meshes whose interior is not visible.
- Сзади:
Treat only the back side of the surface as a light for sampling.
- Front and Back:
Treat surface as a light for sampling, emitting from both the front and back side.
- Прозрачные тени
Use transparent shadows if it contains a Transparent BSDF, disabling will render faster but will not give accurate shadows.
Volume (объём)
- Сэмплирование объёма
- Distance (расстояние):
For dense volumes lit from far away Distance sampling is usually more efficient.
- Равноугольно:
Если у вас внутри или вблизи объёма есть источник света, то лучше равноугольная выборка.
- Множественная значимость:
Если у вас комбинация и того, и другого, то лучше будет множественная выборка по значимости.
- Interpolation
Interpolation method to use for the volume objects and smoke simulation grids.
- Linear (линейно):
Simple interpolation which gives good results for thin volumes.
- Cubic (кубический):
Smoothed high-quality interpolation needed for more dense volumes, but slower.
- Homogeneous
Assume volume has the same density everywhere (not using any textures), for faster rendering. For example absorption in a glass object would typically not have any textures, and so the renderer can be set to avoid taking small steps to sample the volume shader. Usually this is automatically determined by the renderer. This setting provides a manual control for cases where it is not detected.
- Step Rate
Adjust distance between volume shader samples for volume shaders. This is typically used to reduce the step size for procedural shaders that add more detail with procedural textures, when it is not captured by the default step size. See Volume Render Settings for more information.
