Reflection quality?

[AcesHigh]

check this image


the reflection glossiness is set to 0.5... but the quality of the glossy reflection is terrible! How do I increase this reflection quality??

at the shader type (blinn) I increased subdivisions from 8 to 16, but it still looks like crap... what am I doing wrong?

Re: Reflection quality?

Are you using adaptive DMC? If no, use it. Increase the subdivision for the material to 32 or 40. Decrease the antialising threshold to 0.008.

Re: Reflection quality?

where do I decrease the antialiasing threshold? I tried it under OPTIONS > IMAGE SAMPLES > ANTIALIASING FILTER... and the image got all black with a few colored pixels here and there.

Antialiasing color threshold is on the Image samples tab
