Small metal piece reflection problem

[Anonymous]

Hi 

There's been this big pile of headache-causing reflection problem for me that I am not able to solve can anyone suggest something that might help.

Problem - I have been given a surface to render which has 1 mm thick n 10mm in length brass pieces inlaid inside a beige stone. As the stone and brass are almost the same in tint, the metal can't be differentiated as well as the metal is not reflecting naturally.

When metal properties used , reflection aint satisfactory.Tried a lip bit of self illumination to fake shine , but still not happy with the result

What render engine are you using??

Elements like those will need a very strong antialiasing to display correctly. Do not use self-illumination because that will kill any Metalic effect that you created.

Depending on your render engine, be sure that you are using a high value of reflection, or just disable, it, then use the same diffuse color in the reflection color, then darken a little the diffuse color and apply some blurriness to the reflections, (Roughness in some render engines).

Then do not place that metal pice at the same level than the tile, place it just a little higher, maybe tur off shadows on that pice and you'll need to increase your antialiasing for that image. IT will take longer to render, but depending on your render engine, small objects and reflective objects use more samples, inyour case it is both.

BTW it seems your GI solution is very low, there are a lot of GI splotches on the whitish wall on the side, this also will affect how clear that small detail shows.

It is always good to create a separate mask for those elements so you can accentuate the color or visibility in post-production.

Did you try with bucket option in the image sampler or with a less noise threshold value?
