Interleaved Rendering Options交错渲染选项#

Enabled

Toggles interleaved rendering mode for the SSSSS effect on and off. This option enables rendering of the effect in only half or quarter of all pixels with subsequent reconstruction of neighboring pixels using the data from previous frames, significantly improving performance.启用和禁用SSSSS效果的交错渲染模式。使用此选项可以仅在所有像素的一半或四分之一中渲染效果,并使用先前帧中的数据对相邻像素进行后续重建,从而显着提高性能。

The effect is cumulative and works best with Temporal Filter (see below), which reduces ghosting and noise artifacts.该效果是累积性的,并且与Temporal Filter配合使用效果最佳(请参见下文),从而减少了重影和噪波伪影。

Samples Defines the number of pixels to be skipped when rendering the SSSSS effect with subsequent reconstruction of neighboring pixels using the data from previous frames:
  • 1 x 2 — half of all pixels is rendered skipping each second line1 x 2 — half of all pixels is rendered skipping each second line
  • 2 x 2 — quarter of all pixels is rendered skipping each second line and row2 x 2 — quarter of all pixels is rendered skipping each second line and row
1 x 2 — half of all pixels is rendered skipping each second line2 x 2 — quarter of all pixels is rendered skipping each second line and row
定义渲染SSSSS效果并使用先前帧中的数据对相邻像素进行后续重构时要跳过的像素数:
  • 1 x 2 — half of all pixels is rendered skipping each second line 1 x 2 -跳过每第二行呈现所有像素的一半
  • 2 x 2 — quarter of all pixels is rendered skipping each second line and row 2 x 2 -跳过第二行和第二行,呈现所有像素的四分之一
Color Clamping Color clamping mode used to reduce ghosting effect: higher values increase clamping intensity, but may cause flickering (to reduce flickering you can choose High + Velocity). When disabled, translucency has a lag as it is several frames behind. 色彩钳位模式用于减少重影效果:较高的值会增加钳位强度,但可能会导致闪烁(要减少闪烁,可以选择 High + Velocity)。 禁用时,半透明滞后,因为它落后了几帧。

Temporal Filtering Options时间筛选选项#

Fix Flicker Removes bright pixels by using the pixel brightness information from the previous frame. We recommend to enable this option for bright thin ropes, wires, and lines. However, when enabled, may produce artifacts by removing small bright objects.
注意
Can be controlled by render_sssss_taa_fix_flicker console command.Can be controlled by render_sssss_taa_fix_flicker console command.
Can be controlled by render_sssss_taa_fix_flicker console command.
通过使用上一帧的像素亮度信息来删除明亮的像素。我们建议为明亮的细绳,电线和线启用此选项。但是,启用后,可能会通过去除小的明亮物体而产生伪影。
注意
Can be controlled by render_sssss_taa_fix_flicker console command.可以通过 render_sssss_taa_fix_flicker 控制台命令进行控制。
Frames By Color Toggles accumulation of a variable number of frames over time depending on the pixel color difference between the current and previous frames on and off. If the pixel color in the current frame differs from the pixel color of the previous frame a lot, these frames aren't combined and blended during TAA. When enabled the image becomes more sharp but it may produce additional flickering, thin objects may be blurred (e.g. grass, metal structures, wires, etc.). Disabling this option may result in more noticeable ghosting effect.
注意
Can be controlled by render_sssss_taa_frames_by_color console command.Can be controlled by render_sssss_taa_frames_by_color console command.
Can be controlled by render_sssss_taa_frames_by_color console command.
随时间切换可变数量帧的累积,具体取决于当前帧与先前帧之间的像素色差。如果当前帧中的像素颜色与前一帧的像素颜色有很大不同,则在TAA期间不会合并和混合这些帧。启用后,图像会变得更清晰,但可能会产生额外的闪烁,细小的物体可能会模糊(例如,草皮,金属结构,电线等)。 禁用此选项可能会导致更明显的重影效果。
注意
Can be controlled by render_sssss_taa_frames_by_color console command.可以通过 render_sssss_taa_frames_by_color 控制台命令进行控制。
Fix Blur Toggles Catmull-Rom resampling on and off. The option allows you to reduce image blurring when the camera moves forward/backward. It is recommended to disable resampling at low settings.
注意
Can be controlled by render_sssss_taa_catmull_resampling console command.Can be controlled by render_sssss_taa_catmull_resampling console command.
Can be controlled by render_sssss_taa_catmull_resampling console command.
开启和关闭Catmull-Rom重采样。该选项可减少相机向前/向后移动时的图像模糊。建议在低设置下禁用重采样。
注意
Can be controlled by render_sssss_taa_catmull_resampling console command.可以通过render_sssss_taa_catmull_resampling控制台命令进行控制。
Antialiasing In Motion Toggles improved anti-aliasing in motion (for moving camera and objects) on and off.
注意
Can be controlled by render_sssss_taa_antialiasing_in_motion console command.Can be controlled by render_sssss_taa_antialiasing_in_motion console command.

注意
Can be controlled by render_sssss_taa_antialiasing_in_motion console command.可以通过render_sssss_taa_antialiasing_in_motion控制台命令进行控制。
Preserve Details Controls the TAA detail level: the higher the value, the more detailed the image is. At the value of 0, the image becomes blurred when moving the camera, however, the TAA effect is better. At high values, this option may produce additional flickering. Thus, to improve the anti-aliasing effect, you can decrease the value; to minimize blurring — increase it.
注意
Can be controlled by render_sssss_taa_preserve_details console command.Can be controlled by render_sssss_taa_preserve_details console command.
Can be controlled by render_sssss_taa_preserve_details console command.
控制TAA细节级别:值越高,图像越详细。值为0时,移动相机时图像会变得模糊,但是TAA效果更好。高值时,此选项可能会产生额外的闪烁。因此,要提高抗锯齿效果,可以减小该值;最小化模糊-增加它。
注意
Can be controlled by render_sssss_taa_preserve_details console command.可以通过render_sssss_taa_preserve_details控制台命令进行控制。
Frame Count Specifies the number of frames that are combined and blended during TAA calculation. The higher the value, the more frames are combined into the final image and the better anti-aliasing is.
注意
This value is used only when Frames By Velocity option below is disabled.Can be controlled by render_sssss_taa_frame_count console command.
指定在TAA计算期间合并和混合的帧数。值越高,将更多帧合并到最终图像中,抗锯齿效果越好。
注意

速度帧

Enabled Toggles accumulaton of a variable number of frames over time depending on the pixel velocity difference between the current and previous frames on and off. Reprojection of pixels of the previous frame is performed taking into account the velocity buffer and the result is combined with pixels of the current frame. This option reduces blurring and ghosting in dynamic scenes with a lot of moving objects.
注意
Can be controlled by render_sssss_taa_frames_by_velocity console command.Can be controlled by render_sssss_taa_frames_by_velocity console command.
Can be controlled by render_sssss_taa_frames_by_velocity console command.
随时间切换累积数量可变的帧,具体取决于当前帧与先前帧之间的像素速度差。考虑到速度缓冲器,执行前一帧像素的重投影,并将结果与​​当前帧的像素合并。 此选项可减少动态场景中移动对象很多的模糊和重影。
注意
Can be controlled by render_sssss_taa_frames_by_velocity console command.可以通过 render_sssss_taa_frames_by_velocity 控制台命令进行控制。
Threshold Specifies the threshold value defining sensitivity to velocity change (velocity threshold at which pixels are treated as fast moving).指定阈值,该阈值定义对速度变化的敏感性(将像素视为快速移动的速度阈值)。
Max Frame Count Sets the number of frames combined and blended for pixels that don't move relative to the screen space.设置相对于屏幕空间不移动的像素组合和融合的帧数。
Min Frame Count Sets the number of frames combined and blended for fast moving pixels on the screen.设置为在屏幕上快速移动的像素组合和融合的帧数。
