Hey,
Take a look at the screengrab, here is what happens.
A Grid with Mountain SOP, then Facet to get normals. Applied material with mirror like reflections.
Behind this Grid is Torus with red material applied.
Then what happens is, normals of grid are so steep, that they reflect incident rays towards Torus, and I can see it in reflections! Im new to Mantra, is it normal ? How can I avoid such reflections. ?
Cheers!

it sovled my problem, if I raise Reflection Angle to >0. thanks for that!
But the issue still exists if I apply even slightest bump map. Then I get red color all over the place.
any ideas ?
