mental ray render problems(MRRP001) issue in render transparency object

If you can't render current image though the glass with mia_material_x ， result was nothing, Please check out below:

1) The transparency mode is "thin wall" instead of "solid" under "Advanced Refraction"。

2) Index of refraction must be 1.0 if you wouldn't need real refraction effect。

3) Check out the outside object's texture , the filter maybe to 0.0, because this default setting 1.0 may take final render blur, if they thought the glass and far。
