Brushed metal problem

[everydayobjects]

Hi, I am having a bit of trouble getting a brushed metal material to work on a fork I am trying to render. It does something strange to the surface. I have tried changing all of the material properties, but it still distorts the upper fork surface. Anyone have any ideas? Thanks, Gavin

The fork. Notice the weird distorted tynes.

This shows the geometry rendered with the default material.

This shows the wireframe of surface being affected.

The same surface rendered with the brushed metal.

maybe you could try to have new model without the teeth and create a transparency map ?

Hi JP, Nope, can't do that as the edge has a fillet.

Couly you check the rendermesh per meshmanager? Could be the mesh quality is to low - brush effects need much polygons some times. Here is an old bug report, maybe it's the same problem here.

Hi Micha, It doesn't make a difference. I tried changing the mesh settings, but the result is still the same.

can't you do an highlight near the edges of the map you're gonna use ? This will create the illusion of your filletedge.

Hi JP, Can't do that either, as there will be some closeups. I am guessing it something to do with the mesh.

I finally sorted it out. Micha was right. I needed to increase the mesh density significantly. In the end, I had to use a max edge length of 0.3

An other solutions is to export your low poly object and assign a mapping per free tool uvmapper. Most the RCM mesh produce this artefacts.

post your new rendering to see if it worth it

Still not quite there, but close.

really nice work - can you give us a rundown of your settings (hdr etc)?

hi,
it looks like there is a bump in the table.

why does the knife handle design is bigger than the two others.
a little bit very light splotchy

The hdri I used was the abstract room one from the tin can guy. The render is still a bit splotchy as it was not done on full quality settings. I find that the Stainless steel looks more real when it has more noise. The cloth one the table is just a scan of a cushion I have here... No bump map.
