vec3 col = textureLod(iChannel0, UV, 4.).rgb;如图：
实际用的时候：
color = textureLod(texture,v_uv0,4.).xyz;
我直接用textureLod会参数错误，textureLod好像被编译成texture2DLod了
'fragTextureLod' : no matching overloaded function found:
我的是2d的纹理，前两个参数直接传2d图和vec2么？
我这报错是因为参数还是需要包含什么头文件?
opengles3.0才支持你试试在creator3.0写，似乎2.4.3只支持编译到opengles2.0
需要包含一个文件
