    the image effect of EdgeDetectEffectNormal just work on the object which is diffuse,if the object is using a shader that have the "RenderType"="Transparent",the edge detect will not work.
    ? why?

    The effect does not work on alpha blended objects because they don't write into the depth buffer. Alpha cutout shaders do however so if you can switch to one of those it will work.

    but i have do something test.i write a simple shader,the object only Edge detected when i write "RenerTye="Opaque" or "RenderType=TransparentCutout" in the shader.(all other things in the two shaders are the same)
    so, do u mean that the only the RenderType=Opaque and RenderType=TransparentCutout can cause writing into the depth buffer?
