① 哪位大侠可以找到如图的纹理图片，要很清晰的图片哦 最好是A4纸大小的图片。（一定要一模一样的纹理）急
这是布料或织物，到聚搜图纹理搜索，有你满意的。
② 3DMAX VR谁知道如何把做纹理贴图的时候如何把材质球调成方形的
按M键，在面板的左上方有一列按钮，按下圆柱体按钮出现一排形状按钮，选方形
③ 请问C4D怎么做这种纹理的球体
④ openGL如何给一个球体纹理贴图,并且当求转动的时候，纹理要随着球一起转动，要c++的详细代码，重谢！

这是OpenGL红宝书的例子，稍作改动，以显示球体转动时纹理是跟着动地。还有原来例子画的是Teapot.。。。
⑤ 请教MAYA球体贴图问题
平面映射比较好~选定一半个求面，再平面映射到合适的轴，虽然要映射两次，但是到时候的UV就直观多了，因为是圆形的，跟你的图片差不多，直接把那两幅图片在ps调整对应上UV的大小就可以了。
