Title: Metal stuff
Post by: DriesV on April 30, 2013, 05:37:06 AM
This is part of a project I'm currently working on.
What you see are the bottom parts of the connection arrangement for our LST radiator (low surface temperature).

Many thanks to John Seymour for hooking me up and getting me started with an awesome brass/copper material. Thanks, John! ;)

HDRI used is standard, unaltered KeyShot library HDRI. All materials (except copper pipe) use standard KeyShot textures.
For the threads on the brass end tap I used the insanely effective "thread_norm.jpg" normal map. Great job on that one, Luxion!

I hope you like it. :)

Nice one Dries... the brass looks really effective - great modelling by the way

Thanks! ;)

Here's a shot of the complete arrangement with TRV head fitted on top.

Stunning results Dries..material and textures are looking good..and second one is awesome..

Thanks, Aldo.

Btw, anyone out there with a good textured material for galvanized coatings (hot-dip and/or electroplated) WITHOUT the typical spangle (crystal-like flaking)? ::)

Something like this:

As always very impressive Dries.

Would it be possible to share that brass/copper material or pass on John contact details so I could ask? I work in the refrigeration industry and use a lot of copper tube and fittings, so that material would really benefit.

Glad you like it, Ray! ;)

As to the brass/copper material of the pipes: I can't share the texture that I used as it is courtesy of John. Maybe you can send him a very nice PM? ::)

In the meantime...
Maybe you can try fiddling with these textures (http://www.cgtextures.com/texview.php?id=15872&PHPSESSID=hada2fmm6pugj9bf8la97s0li3). They look pretty good for a plain colored, yet not perfectly finished brass material. It can be easily turned into copper in KeyShot by blending the color texture with orange.

I do acknowledge that metal materials can be very tricky to make. Especially the ones that appear quite rough in dim light, yet appear quite specular when exposed to a bright light source, yet always have very blurred reflections. Does that make sense? ??? Something like the metallized solid brass cast parts in the images...

Thanks Dries. I'll have a play with those textures and see what I come up with, cheers! I'll contact John aswel to see if he would be so kind to share that material.

Here is my Galvanised Steel... but I'm afraid it shows the flaky bits (I think)

Anyway, here's a link to the file... I'm not sure where this is from, it might be from a collection I made a while back or it could be from elsewhere...

http://www.mediafire.com/view/?x9b80r5tu50xab1 (http://www.mediafire.com/view/?x9b80r5tu50xab1)

If it's not what you require, then post some images of what non-flaky galvanised metal is...

John,

Yes, that's the typical galvanized coating with crystallite spangle. ;)

You can see some examples of what I'm looking for below.

Also this more reflective version for nuts and bolts. ;)

OK, I can see the images, but I can't get a handle on what defines a non-spangly galvanised look...

To my untrained eye, it just looks like slightly dirty, greasy metal - although in most of the images you've posted I can still see some evidence of Crystallization...

It's sort of a matte blueish gray look. Not entirely smooth to the touch too. Also subtle irregularities in color (tint/blueish hue), specularity and roughness.
Overall it appears quite blue and matte in daylight. Daylight accentuates subtle surface irregularities.

Does that help? ???
I'm going to investigate this some further later today. :P

I could play forever finding the correct combination of bump and diffuse - but unfortunately at the moment for me, time is at a premium

So here is the same material I've built rendered under different lighting conditions (different HDRI)

I don't think It's quite there, but it looks OK to me and even if it doesn't pass muster for this project, you could probably use it in another

Some early results in my quest for a good non-spangle galvanized material.
Both a rough and shiny version. The two materials are pretty much identical, except for roughness, texture brightness/contrast and bump height.
I'm using the advanced material type, mainly for control over IOR.

I'm pretty happy with it. The material shows all the irregularities within the coating surface, yet has no spangles. :)

note: model is some frame assembly from grabcad.

Are you willing to share that mat Dries  ;)

Title: Re: Metal stuff
Post by: DriesV on May 02, 2013, 02:54:46 AM
John, it's basically an adaptation of your brass material. I shifted hue, turned down saturation, flattened color variation. I made a bump map based on the diffuse map.
So... am I allowed to share this material? ???

Dries
Title: Re: Metal stuff
Post by: Despot on May 02, 2013, 03:55:02 AM
Ah... I didn't realise that was case Dries - thought you'd used your own maps for this - I would rather you didn't share this publicly...

The same galvanized coating material on an electric motor assembly (grabcad model).
1 material, 2 different environments.

Fantastic. Is there any way for you to share the materials with us so we can include them with the next update of KeyShot?

The galvanized material is a derivative of John Seymour's brass/copper material. Since he has decided to share his material publicly, I should be able to do the same with the galvanized coating material.

I'll upload a ksp file of that electric motor scene tomorrow morning...

If you want to send it directly to me - thomas@luxion.com - then I can collect them and include them in the next update.

BTW - what size are the textures and what is the dpi on those?
Title: Re: Metal stuff
Post by: Despot on May 14, 2013, 02:47:29 PM
Dries, if the .ksp uses the bump map that was in the file that I sent you only, then I don't want it sharing. If it includes one that was derived from the diffuse or the bump map that was included with the package that I shared publicly then that's fine...

I indeed derived the bump map from the diffuse map.
Thanks for clarifying, John! ;)

Unless they have been reduced im size Thomas, the original maps were 2048 x 2048 at 72dpi...

Hi Dries, How are you?
I need a tutorial to make this bucket. The help is very important for my work.
Thanks
