模型纹理显示错乱，求救.....

forgy

小弟新手，有没有大神知道这个问题是怎么产生的吗，模型的图片怎么显示的有些位置变色了？跪求解决方案，shader代码如下，es2.0
static const char vertSource[] =
"uniform sampler2D u_samplerTexture;\n"
"varying highp vec4 color;  \n"
"void main() {\n"
"    gl_Position   = gl_ModelViewProjectionMatrix * gl_Vertex; \n"
"    color = texture2D(u_samplerTexture,gl_MultiTexCoord0.st);\n"
"}  \n";

static const char fragSource[] =
"precision highp float;  \n"
"varying highp vec4 color;\n"
"void main() { \n"
"  gl_FragColor = color;\n"
"} \n";

把访问纹理的操作放在片段着色器里面
