--- Maya2OSG - OSG Maya Exporter 遇到的问题 ---

yuanloo

我使用的时maya2010,OpenSceneGraph-2.8.2。从sourceforge.net下载发布版的maya2osg-0.4.2-src。在vs2008下编译好，maya2osg插件成功安装在maya2010。现在打开的是maya2osg-0.4.2-src带有的测试例子particles。点击maya2osg插件的第二个按钮，在maya的output window窗口得到如下的结果：

总结起来有以下两个问题：
1、ERROR. Unknown node type : |curve1|curveShape1(kNurbsCurve). Ignoring node.
不能识别该节点，忽略掉。
2、Error writing file E:/12-30golfexport/particle: Warning: Could not find plugin to write nodes to file "E:/12-30golfexport/particle".
没有找到插件读取该节点。
最后导致的结果是，在指定的路径下根本没有所需.osg文件。

kNurbsCurve肯定是不识别的，因为这是NURBS曲线，请转换成polygon之后再导出
文件名particle似乎也不对，您至少得加上一个.osg的扩展名
