    Default Newbie Challenge #1 (ZB3) - Make A Brush

    New to ZB3? Totally lost and don't know where to start? A bit more experienced, but rusty on alphas, or bemused by creating brushes? Then this challenge is for you!

    There has been some criticism that the literature for ZB3 has not been aimed at the total beginner. So I got to wondering .. what subject would get you quickly into the ZB mindset without drowning you in detail? The answer is Alphas and Brushes. And I'm not going to give you reams to read. No sir. Instead, I've created a series of 4 video tutorials, all accessible to the true newbie. Recorded live, with commentary, I'll take you gently through most major aspects of alphas. And in the final video we'll create our very own brush .. for that is the challenge .. Create a Unique Brush.

    Video 1 (12mb) : we take a leisurely stroll around the alpha palette, and consider enough technical info to get you started, without getting all geeky.

    Video 2 (11mb) : we'll create our very own alphas from 2.5D painting and 3D sculpting.

    Video 3 (18mb) : we'll use 2D data (from photos and from painting in ZBrush) to create 3D alphas.

    Video 4 (22mb) : in this monster vid we make alphas from ZSpheres and parametric objects, we save one alpha into the Alpha palette and use the other as a base for a unique brush. We explore the brush settings and the Brush Master, and then look at brush trouble-shooting.

    Phew! There's a lot here, but it should help get you started with the programme. There's no pressure to take part in the challenge itself but if you want to, simply post shots of how you've used your new brush, or pictures of your alphas, or share alphas or brushes with the community. Go to it! There's no time limit .. join in when you're ready. As always, the more experienced users are welcome to take part, or take me apart (if I've messed up anywhere!).

    I would like to see this happening since I don't know too much about alphas.
    The sound doesn't work on this video for me.
    Also the video quality is very very poor...
    Maybe make a better version? Sorenson 3 codec for Quicktime is very good.
    Can't watch these since they're very poor...

    That's a shame. Have you loaded the TSCC codec? It's a lossless codec and although I had to reduce the size of the video to make the d/l size sensible, I can see all the text when I play it back at 200% view size in Windows Media Player. And hear my voice too.

    Hello Moochie,

    As a new ZBrush user, I really appreciate these videos. They are well thought out, thorough, and easy to understand.

    Thank you for creating these!

    Sincerely,

    Excellent, Sonja! That brush has some nice crisp edges .. did you do any tweaking in your graphics program before loading the photo in ZB? If you did, please feel free to let everyone know what techniques you used. A great start .. yay!

    Thanks to everyone else for your kind comments. I'm still learning how to use Camtasia to capture sessions, so if any more experienced users know the best settings to get nice clear vids with the lowest possible memory, then please do say.

    Hi Moochie, it wasn't a photo, it's a quick black on white drawing I did in ZB2 with the Zketch plugin a while ago. I'll cut the head out, invert the colors and paint a bit more black on it.

    A photograph of a BMX stunt rider was used to make the alpha.

    Hi Moochie and aminuts,

    Thanks for your kind words.

    @aminuts. Thanks for asking, here are the construction details:

    The original picure was 3405 x 2336. Here's a thumbnail version of it:
    BMX-full-frame.jpg

    Photoshop CS2 was used to make the alpha:
    -a 1400 x 1400 section was cropped from the original
    -the background was selected and removed using the Magic Wand on the blue channel;
    -the dodge tool was used to lighten the darkest parts;
    -some blurring was added to remove some details; and
    -a black background was added.
    - This was saved as an 8bit per channel Photoshop PSD.
    BMX-IMG_0030-8bit-alpha.jpg

    - In ZBrush, the document size was set to 2048 x 2048.
    - The half medallion was made with the PolySphere.ztl tool (not the Sphere3d: the PolySphere can be loaded using the Load Tool button). One half was deleted and he Size tool was used on the Z axis (with a negative value) to squish it. Then, it was subdivided to 3 million polygons. The material was set to Intensity metal.
    - The alpha was imported directly using the Import button on the Alpha menu.
    - In Projection Master, a golden yellow colour was selected. The BMX Alpha was applied using the DragRect stroke having the Intensity set to about 5.
    - The stars were added using Alpha 10 and a Radial stroke having M Repeat set to 24 and the Draw Size set to about 25. This made really big stars!. The Gyro (press W) was used to make them smaller.
    - Projection Master Pickup Now was used to pick up the tool.
    - The tool was rotated and the lighting adjusted a bit. The document was exported to a Photoshop PSD file. In Photoshop, the Save for Web feature was used to reduce the size of the image from 2048x2048 to 512x512 and convert it to JPG.




    Cheers,

    George
