出现如图效果,如图:

纹理过滤模式设置不当,
\
sampler ShadeSampler = sampler\_state\
{\
AddressU = CLAMP;\
AddressV = CLAMP;\
\
Texture = (ShadeTex);\
MinFilter = LINEAR;\
MagFilter = LINEAR;\
MipFilter = LINEAR;\
};
设置为默认的即可,
sampler ShadeSampler = sampler\_state\
{\
Texture = (ShadeTex);\
MinFilter = LINEAR;\
MagFilter = LINEAR;\
MipFilter = LINEAR;\
};
正确效果如图。
