Brushed effects

[AdamT]

Interesting problem. It's not accounted for by the built-in anisotropic shaders, as you found out. I tried to make a "real" anisotropic effect by using radial lines in the bump channel but it leads to insurmoutable AA problems as the lines converge--even at 16x AA. Looks like a job for PS unfortunately.

Thanks Adam. I was starting to think I was just being thick.

This is a real problem for me as I will be designing watches and about 50% of them have this sunray dial.
I'am still using the Demo to practive and if I cannot create this effect in Cinema 4D then i'am going to have to look at other programs.I dont want to but I cannot tell my boss to spend over a grand then tell him that I cannot use it for 50% of our work.
This is a shame because I have truely fallen in love with this little prog.:sad:

I can create a texture in photoshop for this no probs but can anyone suggest a material setting for me? I asume I use the texture file as a bump map so it can catch the light. Sad thing is that the anisotropic settings look realy nice but I will be using them for other dial types.

I'am still training in 3D could you perhaps help me out and suggest a material settting to use for a sunray effect dial using a photoshop created texture? It will be used for Gold,silver and any colour and black and white.

[EDIT]
just reread your post and see that you have already tried to use it as a bump channel.
Thats me done over then. Whats an AA problem?

Right! I'am throwing down this challenge. The person that solves this and alows me to be able to get C4D then you get to name my first born!

BTW speaking of colours is their a plugging that alows you to use pantone colours?

samir's dpack and separate procedural set has a noise function called beams which might be of help in doing it...its not anisotrophy/bdrf stuff...its just the patterning and you can't unfortunately load a material/shader into danel, nukei or lumas in the anisotrophy channel...however i imagine using specular colour and diffusion might help fake things like this pretty adequately anyhow of course you won't have multilayers of specular which you have with lumas but might be able to use in fusion/layer shader in combination anyway...there was a thread on metals and some preset metals claudio72 did ages ago which "might" be worth looking at...whether they will help you with the radial part dunno but worth looking at non the less i would say.

[flingster]

that beams procedural might not be right after all as your maximum amount of beams is 50 which is unlikely to be enough...sorry.
as adam says photoshop job really for your base beams look.

Bummer. Really 50%? No accounting for taste I guess. :)

Stands for anti-aliasing. Aliasing is the moire effect you see when you try to represent closely-spaced lines in print or video. AA is an oversampling technique designed to combat the problem. Problem is, the sunray pattern is just incredibly hard to deal with because of the convergence of the lines. Much as I hate to admit it I really can't come up with a workable solution for animation. For stills you could just paste a PS texture in there, but that obviously wouldn't give you the dynamic effect you're looking for in animation. Hopefully someone else will chime in with an answer.

Is this (http://members.cox.net/jasonconrad2/thisone.pict) the effect you're looking for? I'm sorry if I missed something, but I just woke up and I'm a little sluggish. This took about 2 mins in the R9 Demo. To achieve this effect, I created a Disk generator with +Z orientation and applied the Danel shader to it. I turned Anisotrophy on, set it to Radial Planar, applied it to the object, and changed the texture Projection to Cubic. Let me know if this all makes sense.
Oh, and BTW,

I've always liked "Skeletor" if it's a boy. I can't think of any good girl names, so you've got a 50-50 shot at getting lucky :)

[AdamT]

Is this (http://members.cox.net/jasonconrad2/thisone.pict) the effect you're looking for?No, the lines in your example run parallel to the circumference, where the lines he's trying to achieve run perpendicular.

Ok first of all can somebody point out what you guys are looking at? I'm not sure what he is trying to do. Looking at that watch face what are you looking at?

The grain on the dial. all the "scratches" come out from the center towards the edge.

Ok I think I see it. Let me try something.

[MrBook]

Ahhh. I knew it was too early for me to be fielding questions. Well, I've had a cup of coffee and made a second attempt. This one's a real kludge, but I think some minor tweaks could get it to look the way you want. You can see it here (http://members.cox.net/jasonconrad2/orthis.pict). I used 36 seperate slices of a disk and duplicated them every ten degrees around a circle. Each one has Danel applied to it. As you can see, the grain is actually still perpendicular to the radius in places. I don't think this would be hard to fix, though. Anyway, I just hope you can get the boss to go for C4D. Remember, we're always here to help.

[EDIT]
Fixed (http://members.cox.net/jasonconrad2/anotherdisk.pict) the scratch direction. The problem is that they're still 36 seperate objects. Combining them into a single object screws up the anisotrophy. This makes it difficult to add any detail to the geometry of the watch face. I wish I knew something about BodyPaint :banghead:. Perhaps there's a solution there.

Thanks m8, I hate to say this but this more closely resembers another watch dial effect. It's rarely used nowadays and the name escapes me for the moment. If I used this it would cause confusion.

If I have to map a photoshop file to every watch I create it's going to muck up the workflow a bit. It's do-able just not very fun!

[dfaris]

Ok hows this? I left it kinda rough but is this what your after?

[OamadeusO]

Dfaris you are a star m8!:thumbsup:

Thats the effect. just need to get the lines to finish closer to the centre and thats a wrap!

Is it possible to get the light effects that you get when you use a anisotropic effect?

Sorry to be a pain but I need to be sure that the package can do all the jobs I need it to. Once I know that I can get the money for the retail version and get some real practice in. I look forward to the ability to save my WIP.

First yes you can get the lines to finish at the center if you wish and yes you can get the anisotropic effect.

The problem is that I did that material using darktree and using that darktree in C4D.

I would think you could do it in C4D and will give it a try in an hour or two.

[OamadeusO]

Cheers dfaris!

If you can help that would be great but it's friday night and I don't want to cause you hassle. Don't feel you have to bust a gut on my behalf. Anytime would be great!

Never say die:

Bad news is that it took 5 minutes to render due to max AA settings. But if you can live with this:

http://www.3danvil.com/Anisotropic_no_lines.jpg
It renders very quickly.

[OamadeusO]

Nice one adam!
5 mins will be a bit extream for previews but it could do the job for the final render.

Suppose I could swap between the 2. At least I know it's possible now.
Going to tell the boss to get his credit card out!

What is the process to create these 2? Please bear in mind i'am a total newbie. Should get that stamped on my forehead the amount of times I have to say it!

Thanks also to dfaris! I'am still curious to see what you can come up with.

Glad I joined this forum!

[AdamT]

Thanks--couldn't stand to give in so there was no choice! Here's the file for your inspection: http://www.3danvil.com/radial_scratches.c4d

Basically I just combined the "Tiles>radial line" shader in a Fusion component with the Lumas shader. For the quick one just clear the lines shader and set the AA (in Render settings) to Geometry.

[AdamT]

Another version with some variation in the radial lines:

Ok here is one I did inside C4D. Took 6 sec to render.

This thread has gone from Doom & gloom to some fantastic results!
Of course none of this would have been possible if it wern't for me asking awkward questions...... Think I deserve a medal now:D

[dfaris]

HEre is the C4D file if you want to look at it. Real easy setup fast render. You can tweak to get all kinds of effects. Its a zip file.

[AdamT]

Great job dfaris! Can't believe those gradients you did--mad man. :)

[dfaris]

It was a cake walk Adamt. All I did was setup the first knot and the last knot for the gradient then just right click the knot line and click double knot did that a bunch of time and there you go.

I'm sure you and others that know the materials a lot better can tweak it a lot better then I can.

[flingster]

Don't let your efforts go to waste! Post! I'am just hoovering up all the help I can get.:thumbsup:i canned it when i saw adams result..was busy working on it then had a look and voila adam had a slick rick on me...so i just closed c4d down...heh heh.
anyways..in short what i was doing..lumas..in fusion..then used tif with a filter...made the tif in photoshop with noise and then radial blur zoom probably better way but was a quickie. then used coloured in coloured specular with filter colour adjustments really...a little bit of diffusion..
in the lumas i basically left standard..but adjusted to specular channels to wide and not as intense...also added illumination to oren neyar. hope this helps...but the other results are better than my ugly..:thumbsup:

whats the plural for genius then...geni...dunno lets just say your both damn clever and need a pat on the back.

I agree! This has been a damned helpful thread. I learned something today that I didn't even know I wanted to know. Now that's amazing!!

Thanks Y'all http://cgtalk.com/images/smilies/thumbsup.gif

[dfaris]

Well there is no doubt that other folks know a whole lot more about materials then I do. I know a small bit about Darktree so I just try to convert what I do in DT into C4D so I stumble
across stuff. Making materials in C4D is what I think is my weak point so stuff like this makes me figure out ways to work things out.

Any way any help people get from anything I do is a good thing. I own a lot more to the people on this form.

How about the inbuilt Spectral Shader?
Give it a grey gradient for the metal look.

Have a nice day!
