How To Create Realistic Hair With Fibermesh In Zbrush

Hey guys - and this part of this course we're going to start adding, got a realistic hair on Einstein. First, I'm gon na have to delete the kriti mesh that I've done previously for the hair. If I sign I'm just gon na delete that and then going to my sub tool with eyes, -- eyes face on there now how I'm gon na do the hair? Is I'm going to be doing it section by section, so I'm going to be masking parts of Albert Einstein's head and then growing out the fiber mesh from each of those masked areas rather than selecting the entire scalp? That'S our head and extruding it all at once. I rather do it section by section, because I feel that I have more control of where the hairs that I go and it gives me more variation when I do that. So going to my masking I'm going to just select mask out part of Einstein's sculpt there to begin with. Okay, so I think that would be fine and I'm gon na go to the light box here. Go to fibers and I'm going to start out using the fibers one, six zero zfb! This is the best from what I've seen on doing here. You guys can explore some of the hairs available here if you want, but I'm going to use fiber mesh one six zero. If you find what you like, just double click on, it turn off white box and we're gon na see a hair looks like came from a horror movie, but we're going to have to fix the adjust the settings for it. Scroll down there, you're gon na find fiber mesh here, click on that and then you're going to go to modifiers. Now there are some settings here that we need to fix. First thing is going to be the gravity set, the gravity to negative one like I set it to negative one so that the hair is off the characters face. So now it's up there and I'm gon na go to the color. So we have the base color. So this base color is the color from the hair roots to the middle and the tip is going to be the color of the tip here. So we got different areas. There that's going to be filled with color and for the base, I'm just going to make it a little bit of it's going, not gon na be pure white, just maybe a little bit scent of grey there and then for the tip I'm going to make it Pure white, so now we see it there and I'm going to go to max fibers. Now the max fibers is the amount of hair strands there's going to be on this group of hair, so I'm going to just set that max fibers to five and for the length the link is going to be how long the hair is going to be so Right now I'm just doing Einstein, I'm not done I'm not doing it girl's hair, it's not a long hair. So it's still long for a guy, but not that much so I'm just gon na have to bring down the length of that bring it down to 800. So, depending on the character you have, you might want to mess around with these values, and you have to visualize your character's hair. Let down as you are adjusting this coverage is going to be see this setting here. This is also important. This is going to be how thick there is so right now, if I render this out using the BPR, render here, see that the hair is just to take a look like it's grass like Maeda made out of grass, so I don't want it that thick so For the coverage I'm gon na set that to 10, and if I render this again just to see, look at the changes, so you have to render stuff out as you adjust your settings to see if it's exactly what you want. Okay, so I like that better and for the tip the scale tip which is going to be this settings here, the scale tip is going to be the tip the ends of einstein's hair here. So I don't. I actually want it to be a little thicker than the base, so I'm gon na adjust the scale tip 2.7. And what else do we have Jessie err, the segment's? We also have to adjust what our segments exactly what are they now for each single hair? There'S going to be points on each hair strand that you're going to be able to manipulate in ZBrush, although the points are not visible and each single hair is made out of CVS that you could use the sculpting brush to to move it now. I'M gon na have to set this to 15 so that I have I'm gon na be able to move it with ease 15. Now, if you're gon na have a pair cur that's going to have curly hair, you might want to set it higher than 15, but right now I'm a Stein's hair is not super curly. I mean there's a little bit of curl stare and it's a little wavy, but it's not super curly like that, so I'm just gon na leave it at 15 and once I'm happy with the settings here, what I'm gon na do is I'm going to be saving It so that later on, I could open it, see the buttons and use those exact same settings for the rest of the sections of the hair. That I need - and I might also use them for. Am I going to use them for my mustache too, and of course, I'm gon na have to adjust the settings for the mustache, but it's a good start, so I'm just go ahead and click Save and then later on, I could open it again, reload it and Use that same settings that we have here and then I'm gon na click on accept to accept this and then it's gon na ask me you wan na pass preview for the fibers. Yes, I do. I don't want it to like. So I'm just click. Yes! So now, if I go to my sub tool, there's the new subtool with the fiber mesh on there. If I hover my mouse over it there it is, it has its own sub tool. Now I could start manipulating this hair, adjusting it combing it so that it looks like Einsteins, so we can have something like Einstein's there. Now before I start manipulating this with the brushes and ZBrush I'm gon na have to adjust something here. I'M gon na go to the brush menu. I'M gon na go to fiber mesh, go to perserve linked, make sure that the preserve length is set 100, so we are preserving the length of the hair and I'm also going to go to front collision tolerance. This is very important if you want to be able to manipulate your hair shape out your hair with east set it to zero, but that does is it prevents you from breaking through the visible fibers during sculpting, whatever you see visible, and I that's the thing you're Gon na be able to move, but if you said at zero, you will be able to manipulate all fibers much better. All right now, I'm gon na go to my brushes and the brush that I'm going to be using mainly the brush is gon na. Be me using mainly to manipulate the hair, are gon na, be the groom, hair toss, groom, lengthen and groom turbulence. Now, I'm gon na start out with a groom hair toss so using the groom hair toss, I'm just going to just comb it. I forgot to do something here: I'm just gon na make sure I turn off spotlight projection, so I'm just gon na comb, this home Brad, I like to start from the front and then go on the side and just bring it down, hold it down and what I also like to do I like to bring down the intensity of the brush a little lower thirty-six would be good and I could use the move brush to just move the hair a bit, and if you see the hair is a little too short, you can Always use the move brush to just move things, move it down hey, so we got one part of his hair there. Let me see how it looks like when it's rendered. Okay, so now I'm going to do. Is I'm going to mask out the other areas of his scalp to extrude out some hair? I'M gon na go to my face here of Einstein so low that I'm gon na make sure I understand. I'Ve done turn off solo and I'm going to do the other part here just go back to front okay, so it would be fine. I'M gon na go to my fiber mesh and, if you guys remember the fiber mesh that I saved before I'm just gon na go and open that up. Fiber hair and I'm just going to accept that. Because the settings are the way that we want it and just going to my groom, hair toss and just start grooming, it again starting from the front and then going from the side and just moving it down. Combing it down you go and you think I move brush you're, just gon na lift it up. It looks a little flat, so move brush is a very essential tool: red just coloring, the fiber mesh. This fiber mesh is actually made out of polygons. So what you're doing is you're just shaping out the geometry? That'S what you're doing here unmask that make sure you unmask the previous thing that you masked, because you don't want to add repeat the same area to fibermesh. I'M going to do this part here just masking this side check your reference to see where your hair starts and where it ends, I'm going to fibermesh open, bring up my old fire brush I used before and except press. Yes, it's the same process. He just oh and apply your fibermesh, and then you groom it and then you shape it out. I can making sure that my brush is at fibre. Mesh is at zero. Yes, it is I'm just going to now. You see that it starts to go inside the mesh there. There'S no problem just used to move brush. You just bring it out again, just looking at the flow the direction off his hair. So it's going that way and using a hair toss. Okay, move brush to just. I could also solo that and look at mesh by itself, so just using the move brush to move it in place, just bring it down, and if you see that the hair is a little too long a way to shorten it. Is you could hold the shift key and just just smooth it out? Oh, you could shorten it that way, and if you want to lengthen it, you want to make it longer. You go to the groom, lengthen brush and you can just comb it to make it longer all right now, I'm gon na have to shorten this out. Just look at the attention to the length of your characters, hair so for Einstein there it looks like it stops right there by the ear and just use the move brush to move the fibers hey. Let me just see what I have so far when it's rendered so right now everything just look clean. We'Re gon na have to add some turbulence to the hair in a minute right now, I'm just making sure all the hair that I need are there and I'm gon na have to fill this area up right here too. So I'm going to my cell tour. I have a nice head so low that making sure I, unless the previous mask and doing this part here now going to fibermesh load, it up, accept it and press yes, room hair tossed now, when I first started out doing fibermesh, it was a struggle just to Control this as it was right, I figure out some ways to make it easier with the settings that I've just shown you guys from the beginning. I think it's pretty cool how we are able to just comb it real, live, interactively comb, the hair and it pretty cool and using the move tool smooth it down and then just being able to sculpt it with all the brushes that we have, because you could Use all the brushes here in ZBrush to manipulate the hair. You use a standard brush and inflate brush dam standard brush the groom brushes here. You use any brush to shape this out and ask that, and the last part is going to beat this okay open, know that up except yes, scrum it to the side and using the move brush, just move it which smooth it out to char in it. And you could always go back to your old fibermesh, all the previous fibermesh that you've created and adjust it again as needed. Let'S look at what we have so far render this out beep your render. Now, what we need to do is add some curls a little bit of curls here on Einstein. So this part here is a little curlier than that, but I think I'm gon na go more for this type of curl. So if you want to curl your characters, hair, you can go to the groom, twister brush room, twister brushed and adjust your brush size and just sculpt away. So you could make some curls that way and if I render to Sal, let's see how it looks. So we see a little curliness going on there and I just don't like how we could really see that there's a division here between the hair groups, so I'm gon na have to fix toast. So just going back to this group of hair at the top here and this and then I'm gon na go to my move, move brush and just move it down kind of just blend in with the side here with a side hair. So what I'm doing is, I am just trying to bring these two groups of hair closer together around this area. Using the move, brushed could also use the inflate brush. You just inflate it a bit. Alright, let's check it out again, probably could juice a little bit I'll inflate it a little bit more and just move it a bit and move this down and also good the same thing here and here, just bringing them together. Gon na blend it in rate it rate it using inflate brush, make this area a little breaker. Put this down bring this down a bit and what I could do is I could use the turbulence brush to add some hair trance more hair strands. If you guys look here, the little hair strands, sticking out that could be achieved by using the groom turbulence brush and this area here to screw up our hair, and you do have a little bit more variation crank that up a bit, maybe a little bit here. Also - and going in this part here and just breaking that up not too much careful with that going back to the side hair here and just adding some turbulence on there, we get that crazy Einstein, hair they're, also on the side here, a little too straight. Okay, let's see how it looks when it's rendered and there it is. This is actually looking nice. I like this area here I like how I did that see those hair strands that gives more realistic air, and I see that this part here looks a little too clean, so I'm just gon na have to break that up using turbulence turbulent brush again around with Your brush size see which one is gon na, be more effective for what you're trying to do there and your character's hair that you maybe do out or if you're not doing. I sign just make sure that you adjust the settings to match the type of hair that your character needs. I think, probably here and this side needed a little bit of break up, based on what I've seen in the render and give you a little bit of turbulence here, but also solo. Your hair can focus on one group of hair at a time. Let'S see what we have here, all right so much better. We got the hair strand going on there very nice very nice. Now I could look at the back and everything is straight here. So I'm just going to go through each of those hairs, hair group and then just use the groom, groom turbulence brush you're, just your little breakups there, and I could also use the groom twister to just curl those out of it. But this is also a way to blend the hair together using the turbulence and then a little bit of Chris doing fibermesh can take a lot of time, but the end result is really good. So I suggest you take your time just turbulence that seemed with this hair here just add a little bit turbulence, just rendering there you go, and I could definitely use another hair group here, I'm going to do it on the other side. Make sure that you have the previous mask unmasked, so both sides open load up the old, fiber, meshed and, of course, going have to fix some settings here, the link - it's not going to be as high, so maybe you're hot around 100. Probably 60. Okay, I think that's good and accept process turn off solo and groom. Hair strong, just grow them that down and you can smooth it out to shorten it. That'S needed alright, see how it looks like used to light up a bit I like to set the light slightly above, because when we are it's artificial light or the Sun, that's always above us to light. So I rendering using the BPR around there see how it looks like all right, so here we got that going on there. I think that we need to do a little break up here. It looks a little too clean around that area so going to the groom turbulence and let's try groom twist on that too, a little bit twisting and probably used to move brush to move it up a bit render it all right. So we got some break up there like, which is that this here is kind of stubborn in that area. So now what I could do is I could go to my mesh here, unmask that and I could mask out a part here, just a little bit of a little bit of the sculpt and then extrude a fiber mesh from there. Maybe that will add a little bit of break up there, and probably we don't need us much maximum fire burst there just bring that to actually I'll set it one and probably points to so. We don't need that much at all point three: there you go and accept it. Okay. This is just the ED break up to our or geometry here to our hair. It'S a little hard to see because it's thinner, but that's how it is used to move brush to move it down. I think they should give it the break up there. We need there, and maybe I could do a little bit of twisting there. Let'S see I'll go place out all right, so it did add a little bit of something there and what I could do is. I could actually move that down a little lower. If I go to the move tool and try to move this down, you see I'm not really able to move the root down the roots of the hair. So what I'm gon na do something to go to brush and go to auto, masking and turn off, auto mask fiber mesh and just by turning that off what I could do is I could actually move the roots. Also, I could move the hair and I can move the roots, maybe here wherever, when you moving it, where we need to break up, looks like so just testing and rendering things out to see how it looks you got that there. I think that we need to smooth that out probably add a turbulence on there. There you go render again there you go so just by adding simple things like this and going back and masking another part of the sculpt and extruding out a fiber mesh adds a little more variation to the entire hair. In the next section of the course we are also going to use fiber mesh for the mustache and for the eyebrows so I'll see you there
