为什么prorender不能渲染图像序列，我可以使用默认的渲染器渲染出来，并且可以加载序列图像，以及正常的播放，而prorender渲染不出来图像，显示的是黑色的，出现什么无法加载图像什么的，图片在窗口可以播放，但渲染出来之后，给了材质并使用图像序列的面片是黑色的,场景文件已发，帮个忙看看是什么问题，随便用个图像序列帧弄一下
En：Why can't the prorender render image sequence? I can use the default render to render the image sequence, and load the sequence image and play it normally. However, prorender can't render the image, and the image is displayed in black. If there is something that can't be loaded, the image can be played in the window, but after rendering, the material is given and the patch of image sequence is used It's black？it's bug？
