    Post Exporting alpha masks ? (Tutorial: Alpha Mask)

    Hi there,I would greatly appreciate your advice. I'd like to export an
    alpha mask of my model in Z-Brush to use as a cut-out in photoshop for
    futher manipulation. I've been using a flat render with the
    contrast/brightness bumped up to achieve an alpha mask effect. I've also
    tried this effect with best render to have anti-aliased edges. Is there a
    better method than this ? Perhaps an automatic feature ?

    Hi Boozie Floozie, boy that's some handle!!! In regards to your question, there's not a direct export alpha function in ZBrush at this time. But honestly, I think I would just color my object white & my background black - render my scene in Flat render & export my image. Once you import it into PhotoShop, You have the same thing as a cutout alpha. Or - If your looking for a "Bump" alpha, then render your scene as usual - export the image - & when you import it into PhotoShop, convert the image to "Greyscale" & you now have a bumpmap alpha. I hope this helps some? Have a good one..... Mark.

    Use the MRGBZ Grabber tool and capture a bitmap and alpha image from your model. You can then use the alpha palette to export the alpha image as a bmp or psd file. The cool thing about Zbrush alphas are that they use 64000 colors whereas Photoshop uses 256 for greyscale

    Hi,
    Thanks Kruzr and Digits
    Here is some info about the MRGBZGrabber tool…

    By using the MRGBZGrabber tool, you will be able to ‘grab’ both the texture and the alpha from the canvas…

    Note: You may need to choose the proper settings for the TOOL MODIFIERS SHADED RGB and the TOOL MODIFIERS AUTO CROP
