Galvanized material help

[naturalstate]

I have this galvanized metal material downloaded from coronamaterials.com that I'm using for some contstruction animations http://coronamaterials.com/material/galvanized-steel/#prettyPhoto[gallery1339]/0/

Can anyone help me figure out what these weird lines are and how to remove them?

There are also these weird bumps where corners come together. How can I remove these too?
And on this base clip, the lines are showing differently and are more horizontal.

Look in the bump slot. It looks like the material is using a CoronaAO map to simulate welding details in the crevices. It looks like the lines are also from the bump map too.

Thanks.
In the top level of material (Blend) there are two materials. Each of these have bumps. I've unchecked both of these and it still looks the same when rendered. I've also turned off the Mask in the top level of blend and it doesn't seem to change anything at all.
Any ideas?

post a screenshot of that the entire material looks like in the slate material editor

I change the tiling of maps in material and changed camera angle. Some of the lines have disappeared. The object in the background is a sweep with edit poly. Autosmoothing turned off. The box is simple box and doesn't seem to have the same issues.

This lines goes from noise map what has tiled 40 and inputs in refl gloss slot in both shaders.

Bump maps can't be combined like other maps without a CoronaBumpConverter map at the end.

I added the CoronaBumpConvertor right before Map #44 in between the two bump slots. Don't see any difference whatsoever.

I'm not sure what you're referring to. I don't see anything that has tiled 40. Can you please explain?

I just turned off the the Refl Glossiness in both slots and the lines are gone but the rendering seems much more grainy now.

Hi. The material you've downloaded is made in alph7, so it's not an uptodate PBR material, and will not react correct to light etc. I would use the maps to build a new material :)

[naturalstate]

Dang ok. That's way over my head. This material was almost perfect. Wish it was bit easier to make materials.

I'll pay someone to re-create this material. Anyone interested?

Download this or this texture set, and plug the maps to corresponding Corona material's slots. Just don't forget to invert roughness. You can plug height into additional bump slot of Corona normal and dismiss AO as it's not needed.

Nice!
Thanks y'all!

Removed those last two maps and lines went away.
And those other galvanized materials look great too.

Thanks so much for the help!

[naturalstate]

Could I get a little clarification.
So when I'm trying to build this material from cgbookcase.
I put the color map in diffuse, put Corona normal in bump slot and then choose the normal map
Put the height map in the additional bump slot of the Corona normal map
Don't use AO bc it's not needed by Corona.
But where do I put the Roughness map? In the reflection slot?

[romullus]

Roughness goes in to glossiness slot, but you have to invert it. Reflection should be set to 1, pure white, unmapped.
