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"



问题描述: 在FHD(1920x1080)分辨率下,一切正常,但是如果分辨率超过2K(2560x1440),那么车窗透明材质就会变成黑色,而且在动画状态下,甚至能看到一条纯黑切线在物体上划过,把透明物体切成纯黑和正常两部分。请看下面的截图(视频在链接:https://pan.baidu.com/s/1EObmYivnjmtuAJeVE1sVFA 提取码:0lin): alt text ![alt text][3] alt text alt text alt text

这个问题仅仅在高分辨率,或者增加了screenpercentage以后出现。 此外,如果我不给透明对象使用forward shading光照模式,而是使用其他的普通模式,这个问题也不会出现。 alt text

我的显卡是GTX 1080,8G显存。在输出时出现了板载显存不够用,调用共享显存的情况。 其他:如果我将场景中的透明对象,比如火焰和烟雾删除,这个问题可以得到有效缓解。在2K模式下玻璃不会变成黑色。
