Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

motion blur无法正确渲染

alt text

我们在项目渲染中使用了后期场的motion blur,但是在角色和武器的运动边缘会出现如下图不太正确的马赛克。

希望帮忙解决。

谢谢。

图太小,压缩品质低,我不太明白你指的马赛克具体在哪个位置,请指出。我建议在你觉得有问题的帧渲染输出一个大分辨率的图片,使用PNG不要压缩为JPG,然后圈出具体马赛克位置

抱歉,由于之前一直场景在做优化所以无法渲染大尺寸图片。 下面图片中的红色方框区域是Motion Blur问题所在,红框中的运动模糊出现了很奇怪类似马赛克的结晶状物体,我们需要的是手臂上这种动态模糊的效果,是不是因为运动幅度过大或者数值属性的原因? alt text
