That 60s workflow intro at the start is not only useful for professionals that just want a quick look-through, it's also amazing for EVERYONE that has seen this before and wanted a quick refresher. A game changer for sure, that earned my sub.
That quick explanation at the start was so appreciated
You saved me! !
I have textures but saw the wrong tutorial.
Had to carve slowly by myself for two months, now I can finish it in less than a day, thank you so much😭😭😭
Display - fast navigate! The setting I didn't know I wanted so badly. Thanks for an outstanding video Zach :)
Yay Blender 3.0 is here ! Thank you so much Zach, I'm so excited for sculpt January as well :)
Non-color data basically turns off gamma compensation. Gamma compensation changes the mapping of pixel values to brightness and is applied because your eye is more sensitive to slight changes in dark areas than it is to slight changes in light areas. So if it's data that won't be interpreted by your eyes, it's non-color data. (There's probably a gamma setting on your monitor, to play with it.)
Thanks for the info, Darren. :)
Can I just say how much I love this channel? Genuienly love the flow of the tutorials, so easy to understand. The courses are sooo worth it!
🥰
Just what I needed!!!! Thanks!!
I do use fur brushes, but they tend to become extremely repetitive. The best result is to use them simply for a start, then carefully pull up the tips of each with the snake hook tool. Makes very intricate looking hair and fur. Not recommended for objects that will end up as low poly though. I make objects for 3D printing.
Totally agree. In the course, I actually sculpt the entire fur by hand with no alphas at all. This here is a bonus lesson I added for everyone that don't want to do it manually, since it takes very long.
Very helpful and informative video 👍
Very Nice!!
Thanks!
I have been planning to buy this course for a long time, I have been constantly postponing it. But with this video you still persuaded me to do it)
Glad to hear that, hope you will enjoy the sculpting course!
Большое спасибо!!!!Отличный урок! Желаю успехов ☺
Increíble lo que se logra con estos pinceles, muy agradecido por mostrarnos la técnica, y como lograste un acabado profesional.
Saludos desde Argentina y éxitos.
Gracias por los cumplidos. Estamos encantados de ayudarle!

This method is amazing and something I would gladly take a blender course in. I just have a few questions before I pay for the course.
-Do this method alter the shape of the original mesh (the normals)?
- Can you animate the model afterwards?
- Can I use this method on an elastic cartoon character with stretchy bones?
🤩
This is actually deforming the mesh using the Multires modifier. The model can be animated but usually to provide good performance of the model for animation the high level details are baked into textures. The cool thing with sculpting with Multires is that you keep the optimized lower poly mesh and the higher subdivided levels of detail can be switched on and off.
i love you so much
By the way, by choosing non color data mode of texture -- you just restrict blender from converting your colors to sRGB. (so, non-color data basically means "keep linear color space", while srgb is like "compensating visibility of darker colors by taking less bright ones, to avoid colorbending"
In blender, the colors are saved not in 8-bit color palette, but in float numbers (aka R 0.6224 G 0.7253 B 0.5923) so you wont see colorbending in srgb either (since color resolution is much bigger).
ruclips.net/video/izoBj0b-hfE/видео.html&ab_channel=MultLabs this video gives great explanation of that topic. But its voiceover is russian (it has eng subtitles in options tho)
Thank you, I will check it out.
Classic !
Correct me here if I am wrong please: if the fur alpha brushes would have transparency where the fur begins and gets to 100% at the end of the fur we would get from zero to higher standing fur. That's how I am creating my alpha fur textures. They stand with an angle to the base shape almost as they were grown outwards and upwards away from the vase shape.
In ur example they are looking more like stickers.
Also the next advantage playing by the creation of alphas we can get the feel if the lower fur is coming from below the other fur. Hope makes sense...
im probably keep using hair generator with card board texture for that kind of feather look, it can work with very low poly model, geometry node is also a good way to populate a model with other tiny one but for 3D printing the sculpt mode is probably the best way to achieve that.
Of course, if you want to achieve a more realistic look, other methods are better. Here I wanted to focus on how to sculpt these, so they are "baked" into the mesh. Good for printing and these kinds of things.
Yes, more than helpful. I Will finally make My Golden Oozaru
Can't wait for the proposed sculpting tools because multires right now is a bit too heavy.
Yeah, sounds interesting what they want to do, hope this will give a big performance boost.
thanks for the tutorial. it has helped me a lot and the results look fantastic in sculpting mode. But I don't understand how I can export my finished object with textures?
the alphas can only be seen in sculpting mode.
With the alphas you are changing the mesh, this is not affecting the textures. Maybe you're using a Multires modifier, which might be turned off in Object Mode. Increase the View Layers in the modifier settings.
@CGBoost, my computer does not do well with sculpting. What would you recommend to aid my computer with sculpting?
BTW, I love making my own textures. I can take any single image I want and turn it into an alpha & Normal with GIMP or Krita.
Hi, anything in terms of upgrading the graphics card, CPU and RAM would help.
how did you create the alpha-textures?
Thank you! Well.. this process of importing alphas into Blender is really weirdly done, i failed )))
Hi sorry that you couldn't do it, can you tell us what happened?
~ Masha
Zach, is there any way to save those brushes for later use? The way of saving them with images makes a mess of blender file (it also loads them as an external data to your projects if you use it). It does not sem as easy as in Zbrush
This has always been a big problem with blender. Its possible that with Blender 3 asset management this could be better?
@@torq21 Im fairly sure that asset manager is going to be the solution to this problem, and many others like it
There are plugins that allow for saving the brushes such as Brush Manager for Blender: tingjoybits.gumroad.com/l/zLBPz
It isn't done natively though. As Aegisgfx and Torq21 said, asset manager may well be a good solution however.

Hi, are the brushes free as in commercial use also or only for personal use? Thank you regardless, I've learnt a lot about the workflow of sculpting from you.
Thanks! Yes, they are free to use for any purpose. No restrictions here.
@@cgboost wow thanks that is super generous of you. Definitely gotta check out more of your work
is there a way-or is there a plugin-that can load a group of brush alphas in random sequence, swapping them out as you sculpt? I mean as a sculpt brush, not using particles etc.
Yeah, I had the same thought in the past, that this would be great, but there seems to not be a feature like this, unfortunately.
@@cgboost Definitely an opening for plugin developers then, do you think? Or maybe Pablo at the Blender foundation (you know , the guy who's doing all the great sculpt stuff) could be persuaded? 😉
@@involutionOcean It would likely be a very good opening for an add-on developer if there isn't already one out there that does the job.
~ Daniel
Awesome job mate!.... But this texture deform the mesh ?... i mean if the quads take the shape of these texture ..?
Yes. In fact the brush displaces the mesh according to the alpha texture data (black and white hightmap). It's most commonly used with multires modifier for sculpting higher level details. There is also a new type of such textured brushes called VDM (Vector DIsplacement Maps) that allow displacing a mesh not just along the normal direction (perpendicular to the mesh) but also other directions (allowing for overhanging shapes). This is a very cool new feature (not covered in this video) but very useful for quickly applying more sophisticated shapes.
Great tutorial. If this could be combined with the mask brush, you could avoid the overlapping. Just imagine everytime you draw an alpha it automatically masks it out. you could just place another alpha in the gap and it would look fine. Is there a way to do this without scripting? So draw + mask drawn area?
Thanks, Leonard! So you mean that with each fur brush stroke, it will draw the same shape of a mask over it? So that later you have all the fur strokes masked out, and you can sculpt in between? That would be super handy, indeed! I tested this a bit, and by default Blender seems not to offer this option, unfortunately.
@@cgboost yeah exactly! I thought about it when you placed those tiny fur patches in between. There should be a better solution for overlapping. Another approach would be smooth or flatten underneath and then draw the shape (same approach 2 brush actions at once) so it would look more like actual overlapping fur. more like placing an object (like a hair curve for example) on the surface instead of blending the secondary details. I think that would be a useful behavior for that use case. Unfortunately I dont know blenders brush engine and I'm not a good coder, so I dont know if its doable (let's call it "dual brush"). Do you know the best place to propose something like that? Maybe you can use your connections *wink wink*. I guess right now the workaround for overlapping shapes is to copy a bunch of fur objects and snap them to the surface (backside protruding into it). They could also be curves. Then bake them later. What do you think?
*edit* I just had another idea. What about "Textured Snakehook". What I often do with stylized fur is to pull out shapes with the snakehook brush. If there would be a way to influence the shape (default is round) and give it like a "side profile" you could snakehook out hair or fur patches that are pretty much done and detailed.
This is an amazing tutorial however when I use my alpha brush the mesh is really jagged and rough. I’ve got like 6 levels of sub division on though so I don’t know what’s going wrong?
Hi, can you please post some screenshots of what's happening here: community.cgboost.com/getting-started

Is there a way to change the size of the texture brush? I have a smaller model I'm working on and changing the brush radius or texture's x/y/z in brush settings isn't helping. Works fine on the larger surface area like the back in this vid But I have to drag the mouse far out to get the fur to appear, and I'm working on a smaller area like a finger.
Hi, you can change the brush texture size by scaling up or down the radius, or the stencil or the brush aplha in the brush settings. This of course depends on the method you are using to sculpt. If this is a problem of the brush scale reaching its minimum dimension, you might also consider to scale up your mesh just for the sculpting phase. Once you're done with sculpting, you can then scale it beck to its original dimensions.
~ Masha
Taking a Break from Working on (World in bottle)😊
I'd add a new brush inside the draw brush tool so the user could switch between the normal draw brush and the alpha brush.
That is another way to do it, but I like to only change the textures, when the rest of the brush settings are not changing.
Is there a way to import multiple brush alphas at once without having to go through importing them one by one?
Afaik not by default, no. 🙁
How do I add the brushes I need help adding them external please
Can you explain what you try to do?
Are these free fur alphas royalty free? for example I can use this alphas to sculpt the fur of a character in an NFT project without naming you in description or something like that? Thank you very much
Yes, just use them for any project you like, even commercially without mentioning us.
@@cgboost omg, thank you very much. You are amazing :)
How much resolution needs an alpha for good quality? Besides the resolution on the mesh
Since usually I blur the images a bit, to make the edges a bit softer when sculpting, I guess something between 512 and 1024 pixels should be good.
@@cgboost Thanks!
Just FYI, 3.0 Beta is out now you dont have to use the alpha version anymore
Thanks, I know. This video was recorded some weeks ago, that is why it is using the alpha. :)
WSo much problems to make imm brush from zbrush to blender.
I can't find the free version of the brush. When i click on ur link they take me to a freaking beginners tutorial.
It is our resource section, that includes the Blender beginner course, Blender hotkey pdf and also all the brushes. Simply sign up there, and then you find it here: academy.cgboost.com/courses/resources/lectures/31160801
@@cgboost i am srry for this comment. I was stupid i found and course was great 👍.
this link does not take me to any fur and I cannot find any mention of fur on your website. It just keeps looping me around to a course.
This is the correct link: academy.cgboost.com/p/resources/
(In our free resource section there you can find our beginner course, hotkey pdf and also all the sculpting brushes.)
I'm a little confused on where the fur download is. In the video you say its free but when I go on the website, the course is $59. Please Help!
UPDATE: NVM, I found it. just had to hit the little down arrow
@@Sp33k Glad you found it okay :)

I have watched this video about 10 times and have followed every step but I still can’t get it to work. Does it just depend on the model or blender version or anything?
Hi, it depends on what is not working exactly for you. Could you please describe what happens?
In general, this technique isn't using any new feature, so I don't think it's because of blender version.
~ Masha
@@cgboost whenever I’m sculpting with it the model just stretches it a lot and looks all wavy. I have the sculptdraw brush selected and I tried matching the strength and radius of the brush in the video but it still won’t work. Thanks for the help I’m not very good at blender and was really frustrated at first I’m glad for the help
I think I solved my problem I just needed to subdivide more. Sorry for the trouble and thanks for the help
@@shronkeydonkey check if you have the scale applied to your model before sculpting (that is the cause of such issues most often)
@@cgboost thanks I got it all fixed 👍
I can't get the brushes. The Dropbox link is dead...
Yeah, we currently run into a bandwidth limitation. We already extended it, but it seems to take longer to get back. In the meantime, you can quickly contact us here, and we give you an alternative link: www.cgboost.com/contact
Like sunflower seeds
amazing brushes, too bad there must be a gap between each fur thing
I wanna see how to create that creature make a tutorial on the creature

Ohh iam so fast
Love this style. But the retopology is painful.
Yup it is! However, with this paid add-on it goes super fast (also has a 30 days demo): exoside.com/quadremesher/
@@cgboost These brushes are also good for use in texture paint. I made a bump map and used brushes to paint on fuzz instead of complicating my mesh with a zillion verts
@@athompsonian Yes that is great too. You can also bake the final sculpting to a normal map, and then reduce the resolution.
I thought those were feathers not fur
Yeah, it is true, looks a bit like feathers. :)
is it still free?
You mean the brush textures? (yes)
@@cgboost where can I find the brushes? The link just directs me to a course not related to this one?
