3Ds Max - Hair - Part 1

Hello in this series of videos, I'll show you hacking, crate hair in 3ds max now. There are two main ways to grade here through meshes and to splines and each have their uses. For example, if you know credit for an animal, it's best use a mesh they're going to create a long hair like a ponytail, it's best to use splines. You can also use the hair system for things around here, such as grass leaves spikes and feathers. So before I get into any details, let's cover some of the most important things know about here and fur. So first I'll just create a plane, and this is an example of using here and fur on a mesh. So I can go all the way down here and here in fur world space modifier, when I want to put it right here for quick access. So I just click on configure modifier sets. I will increase the number of total buttons to 28 and scroll down here. Find here and fur and drag it and drop it here on the bottom right, ok and now, let's be able for quick access. Ok, so that's the first method, creating hair and fur out of a mesh, and now for the second method, splines are going to click here on shapes line here where it says, start new shape. I will turn this off and what this will do is, if start new shape is on. Let'S say I click several times here and then start looking again, you can see there's actually two different splines, but if I turn off start new shape when I right-click here and end this line, if I click again, it's part of the same object so using this Method, it means that I can have all the splines that clearly part of one object without having to go later in here and attach and attaching them all together if they were all created separately. But now with these flying, selecting a seam click on here and firm, and now we have the hair coming out of these splines as well. So here are the two methods that we can use to create here now. One very important principle for hair creation is interpolation. Interpolation, as it applies to here, is how the hair is interpreted between each guide. Now, when you create splines, each of these splines serves as a guide to the hair. It pretty much tells the hair where it needs to be and how it moves. If I go back to your general spline, this warning pops up, but it's okay. We can click on yes notice right now, I'm in vertex mode under editable spline, but I can't really see the hair. If I click here shorten result on and off, I can actually see the hair the hotkey I have set, for that is space. So now, if I move these splines, you can see the hair follows I'll press ctrl a to select all the vertices and smooth them out and now I can actually control the hair using these vertices, so these splines are acting as guides for the hair. Now the reason I here doesn't seem to be following it too. Closely is because, if I go into the hair settings we have some settings, Chetak interfere with how close these follows, for example, random scale by default. Here, it's a 240. If I right click here notice, how now the hair follows a lot better, because we've got rid of all that random scaling. Another thing that modifies how close the hair follows is here in the frizz by default. Frizz tip is set to a pretty high value 830. If I right click here and also the hair follows a lot better now as well, and in order to make this easier to see I'll just go here under display and turn off, display hairs and go into guides. And now we can see the guides coming out of every single vertex, so these are actually control how the hair behaves. So the hair is pretty much interplay between every single guide. Now we want to keep a template on, because if we turn this off we'll get very few hairs and the same goes for the spine method. If I turn and circle it off, you pretty much just get one here for every single spline, even when using the multi strand parameters. Here, it's still not enough hair to get a good, dense, realistic effect. So definitely interpolation is something you want to keep on, where you kind of have to understand how it works in order to use it effectively, and it's especially important when you're using splines and to give you an example I'll just create a sphere here and I'll just Center, this now I'll go into shapes line and now I'll right-click here and I'll turn our vertex to activate face. So now I have face snapping on I'll just set this to be smooth for both of them. First s activate the snap toggle and now what I can do is simply click the splines. On top of this sphere, let's say that this sphere is a person's head and I want to create a hairstyle on top of this. So I'll just click here there we go right-click to exit finish this line and just go here. So I'm trying to create these bangs here. Of course, you will have all types of hair, but for this hairs that I want to be have these kind of clumps here and I'll also create a clump right here, all right, so there we go now. I will select all the splines to deselect this sphere and alt Q to isolate this. So here is a basic hairstyle. I want it to be a clump of hair here and a clump of hair here so before I select all of these splines and apply here in the fur. I want them to all be one object, so I will clone these off to the side here and what I will do is click on attach and just attach them all together. All right, just like that and now I'll apply, hair and fur and notice how we get. This was all right here. So, of course, first thing I'll do is just turn off random scale, as well as frizz and notice how the hair does not only seem to fall in the splines very well, and I shall reason for this. If I go back into line and I go into spline level and right here in the selection, you can see it says: zero spline selected - if I select this spine here - notice, how it says spline one selected. If I select this line, it says spline, four selected and five, two three and six now the number of the spline here is the order in which I attached it, and you remember that I attach them not in order, but I went back and forth here, which Means that now we have this kind of messed up spine order. Of course, this one is fine number one, because this is the one I selected before I clicked on, attach I selected this finally with an individual object and then attach the other ones, which means this is the first one and the proper method for this is. I will once again clone the cells and this time we'll attach you in the proper order, so I'll click on attach and attach them logically and once again, I'll apply here in fur and turn off random scale and frizz and notice. How here we get a much better results, but of course, between 3 & 4, 3 & 4. We still get this interpolation between here. However, on the 1 2 & 3 & 4 5 & 6, we get a much better. So you can see all the hair is following a lot better, but the downside using slides that we get this interpolation right here, because it wants to go from 3 to 4. Now, when you're using splines, there's no way to really fix this interpolation effect. What I can, however, do is select these slides and scroll down here and detach them as a separate object. I now what I can do is select both of these spines and add here in the fur, and now I get a much better result. Of course, once I turn down the frizz and the random scale, it follows the spine very accurately. So this is how you can get around the issue of interpolation is to select every single clump of hair that you want and make a separate spine object. You get the accuracy that you need. Another thing to note is that when you use splines as hair growth objects, you can't do any styling here. I also want to go into the styling panel. It'S all grayed out here they cannot style it. And, of course, this is because the edible splines act as the guides, and if you want to style the hair, you actually move the vertices around and that second style here using splines and now I'll show you how you can control tribulation using meshes. So here is the original sphere, I'll just add a poly. On top, I will select. Let'S say these polygons and detach is clone, and now I will isolate these objects. First thing I will do is select this edge down, rink loop and remove, and once more now get this much simpler result right here and I want to select these splines and attach them together again and then I'll select this mesh and hair and fur. And I will once again turn off the random scale and the frizz, and I will just decrease the hair count here and increase the hair segments to something like 24 or higher. And now I will do is go under tools. Re comb from splines which allows you to create a hairstyle using splines and there we go now. The reason that I got this was, though I'll just click on the spline go into rendering and turn on, enable in viewport and increase the thickness. You can't even easier you can see. I have spline inches on this section right here. So all the guides for this mesh are trying to match the splines, but there's not enough splines to give them something close to follow. So all of the guides on this side are trying to follow these splines, which creates this ones are right here. I can fix this by doing a little bit of styling. Now I can access tiling using three ways. I click on style. Here I can click on guides. Welcome to the press 4 to switch the guides. All of these methods allow it to style the hair. So now I can use the default here, hair brush and translate, and I can simply style the hair almost like using a comb. I can hold down ctrl shift clicking on the Left, mouse button and move the mouse up and down to change the size I can also simply zoom out and even though this brush is the same size notice how it affects a lot more. So let me do is actually first switch to select and what this allows you to do is only select certain guides for styling. So, let's right now, all these guides are orange. You have a click right here notice how they become, yellow, letting me know they're not currently selected. So let's say I only want to brush these hairs right here, I'll select them, they become orange, I'll switch back to hair brush and now only they are affected. This is a good way to control. Only individual hair is to get a very distinct hair style, and now I will select these hairs, and here I'm just creating a custom hairstyle, not Coulier, to the splines, and now I will select these guides and now I'll select. These last three ones right here: alright, now I can switch to puff routes, tip-top the routes up a little bit and I'll switch back to select control a to select all of the guides, switch back to styling and puff up the roots a little bit there. We go all right and I actually I love styling by Sigma click on finish, styling or started pressing for all right. So here are the results, I'll, isolate this and once again get to see how the problems with interpolation arise. How all the hairs are pretty much interlinked together and don't get those distinct clumps that I want. However, when you're using a mesh growth, there's a simple to fix this I'll go back into guides, select and now what I will do is. I will select these splines. Let'S say I want it to be a clump right here, right here, right here and right here, so basically for clumps select the guys that you want, and here we have hair groups, you can split the selected hair groups or merge them together. So notice have between these guides. You have a tribulation happening. We have here is being formed right here right here, right here and even inside of here. If this was an actual person haircut, they will be here inside their head, which is not missing the step we want to avoid. So with these guys, like that I'll click on split selected, hair groups, I lost this thing for this right here. Split for this right here split and for this right here, squit now you can see you have four distinct clumps of hair. Another interesting I can do is actually set up named. Selection sets for the different clumps of hair, so we're going to guides switch the selection. I will select this hair right here and here are just entered one and press enter, and now, when I click on this arrow and click on the one notice how these guides you can orange letting me know they're selected. Let me do the same for this right here. Press to enter 3 enter and 4 enter, so you can use this to create quick groups of hair. You can quickly select and manipulate. So this is how the hair looks will has been divided into separate groups using split and if I merge it back together notice how we go back to this right here. So this has been a quick look at the two hair creation methods and how to deal with interpolation. Thank you for watching and take care. You
