Reflection Not Smooth (SOLVED)

Hi guys,

 

I have just rendered a scene with a mirror reflection, but somehow the reflection didn't look smooth (picture attached). For lighting, I used UE2 & Set Quality 4XHi + Linear Point Light (100% Intensity, Raytraced 70% Shadow Intersity, Falloff End 500). The mirror setting was Diffuse Colour White - 0% Strength, Specular Colour White - 100% Strength, Glossiness 100% Strength, Reflection Colour White - 100% Strength. Is there any setup to make the reflection smooth?

 

Thank you guys

    What was the Shading Rate in Render Settings?

        If the reflection is jagged, this can be fixed by lowering the shading rate at the expense of render time.  I don't know what's normal or best, but just as an example in one case I tried it was jagged at 1, but when changed to 0.1 it was better.

    It was default: 1. Should I lower it?

    Okay sriesch, I will try it. Thank you

    Yes, 1 is generally OK for direct line of sight but tends to be too high for reflections (or for surfaces with a high glossiness).

    I see, but will it affect the render result of direct line of sight? Thank you for your help, Richard

    It will slow the render down - roughly as 1/shading rate squared as I recall - and should sharpen everything a bit, how noticeable that will be depends on the scene content. It will probably affect the density of any displacement using procedural noise for hair or fur and similar effects.

    Well noted Richard. Thank you
