I’m doing some illustrations with Carrara and I would like an effect where the light source washes out the texture but doesn’t give me pure white.


IE the maximum highlight might be a light grey , but at this point there would be no texture showing.


Any advice on what plug ins if anything or settings in Carrara to do this?

I am rendering mat objects that wouldn’t work if they looked shiny

edit also looking for advice (after Dougs’ comment) on making a pencil effect with procedurals smile

thanks in advance

I would think a procedural texture (not an image file texture) should work like you want it…..adjust reflections, highlights, etc. to controll reactions to lighting.

Perhaps an example of what you want as a result may prompt more specific help.

thanks Doug

I ddin’t want to wrestle with the imageposting process smile


I could do it in post I suppose… I think I need to use textures because my ability with procedurals to establish a pencil effect is non existant.


I guess the best description is if I were doing a drawing on a tinted paper, then I use the eraser to rub off the pencil marks to establish my highlights - which are in fact my original tinted paper - and not white


edit: okay it had a simple answer combination of light and ambient light while changing the degree of shadow gives me close to what I want thankyou - derr I am blind smile


oh any clues on getting a pencil effect with procedurals very very much appreaciated

Hi Head Wax smile


Will the non-photo real renderer work for you? I figure you probably have a reason you aren’t using it but just thought I would bring it up just in case it slipped your mind.


Alternatively there are some things you can do with the “Angle” and “Lit” nodes included in the Shoestring Shaders. I don;t have them installed on my new machine yet so can’t give exact steps but I know you can use them to create masks based on viewing angle and light position. This allows for some fun toon effects in the photoreal render.


Here is an example:

You could replace the solid colors and cross hatching (wires or tile function I think) with some scans of pencil marks to maybe get a more sketched look.

Head Wax,

I think this would be easier to do in post processing. I’ve attached an example of a render that I did, converted it to black and white and then post processed it in a Mac program called AutoPainter. There are a lot of programs that do this kind of effect. you can tweak settings to get exactly what you want.

I like what Brian posted.  You could also look at Plug-ins by Digital Carvers Guild.  Toon pro, maybe Parchement or Shaders Plus.

The unphotoreal renderer isn’t reallydoing it for me. especially in it’s treatment of eyelashes. I wonder if there is a way to make our own brushes for that - as it appears to be close, but not close enough , if you know what I mean?

Thanks so much for that link to your video. Yes I saw that video two years ago and I think that inspired me. I have those shaders but whenever I read the destructions my brain infarcts - so when you get a chance I would love some hints wink wink


I actually sat down and went through them again last night but can’t hit on the right combination - its obviously trial and error. It’s a good idea the pencil textures - they have been my most successful attempts so far combined with post
 


Brian:
 


Thank you too, I have been looking at a few of those programs and see that they are pretty good, I’ll check that out. I had sucess this morning with some tutorials I found involving minimum pass filters and then using the dodge and burn tools to refine the result. So maybe a combination would work - human intervention and cpu intervention?

Milo,

I was checking out the Digital Carvers stuff last night, but it only gave me half a render before it went invisable - so I really didn’t get much joy smile But I have my eye on them. I also tried Yatoon, for Carrara 7 which seems not too bad but not quite what I am seeking.


Thanks for your advice too!


out of interest this is what I have come up with so far

Hm. Not perfectly clear on what you’re looking to accomplish. Are you trying to just do black and white lines?

I’ve always accomplished this by doing the non photo sketch render on green and then keylighting it in AE. But you’re right about the eyelashes, which is why I stack my renders.

Without keylighting capabilities I guess you could still work with transparent PNGs right? So you render out your sketch layer, you then open up the texture maps for whoever the character is, find their eyelashes, make a copy of it, color over the eyelashes with solid black and then replace the old eyelashes, go into the render, turn off the alphas on everything except the eyelashes, render it as a PNG with transparent background, and then stack your eyelashes render atop your sketch rendering.

Personally I wouldn’t go to all that trouble just for some eyelashes. I like to get in there and hand color all the existing textures and then use long brushes in the sketch render to give it a gritty look. But for black and white I think this would work.

Thanks for the outline methodology BC RICE. Ah yes, its no problem to pinch the non photosketch renders and use them with the eyelashes , the NPR is most useful for me as an outliner, probably more of a problem with hair made with transmaps I think, to tidy it up in post.

Yes I like the idea of black and white at the moment. I’m trying to widen my portfolio and this is something that will help me.

Black and white tends to be have less of a CG look sometimes. And I have been colouring it with water colour brushes in photoshop - using the NPR outliner as a separator for the individual sections of the image.

As an eg of what I admire and sort of would like to do ...



This is a piece by the guy who illustrated Jumanji and Zathura , both briliant works in black and white - well what I have seen at least. He uses a textured board under his paper to get his effects in Zathura - very effective. This is a poor example I am a afraid.


I spent a few hours today trying to simualte a few textures if PDPro - not a bad program of sorts. Would have been quicker to get a graphite pencil and draw them though wink

Thanks again wink

This is about where I am with tooning DAZ folks. This is done strictly in Carrara using YaToon and fooling around with the textures. I’m happy enough with it. I’m still undecided about whether or not to use sketch layers. I suppose it’ll depend on the project.

HI Head wax smile

Have you thought about Filterforge for photoshop.

I just did some messing around and made this filter which adds various sketchy type effects.

Head Wax,

These look great. I see what you mean about the Jumanji pictures. They really are different.

Good luck.

Good stuff. Man, if Filterforge came with an AE counterpart in the package I’d be all over this. $140 (which is the sale price) might be too rich for my blood. I know you can do PNG sequencing through Photoshop and could grab renders that way, but I pretty much stick to AE for moving things.

For stills, though, this is pretty neat.

Oh, and this might be the kind of thing the OP is looking for? You’re just looking for black and white solids right? Maybe research this guy who’s been doing it.

HI BC Rice smile

Thanks smile

They have a free download (stand alone and plug-in) version,. so it’s not limited to just being a PS plug-in, although it’s better inside PS.
and they offer a system of awarding points for uploading filters you make,.
so it’s possible to make some filters using the free version, ..earn points, and get the full version, ...or at least a discount. smile

I’ve spent hundreds on packs of filters like Eye-candy, which are still great plug-ins, but with filter forge I can make my own, or download free filters from the library. 

I also use Xara designer pro,  for vector drawing, and it can use PS Plug-ins as “live effects” on vector artwork, so, I can also use Filter forge there.

I agree with you,.. It would be great if it had animation properties, and could be used inside AE,
but you can still use the filters to create all sorts of masks and textures and use those in AE, either as 2D masks or as 3D layers.

Try this as a starting point, simple cross-hatch “fractal noise” shader

Hope it helps smile
