Nion’s Blender Tutorial: Clipping Masks


https://i.ytimg.com/vi/Sig6i9MrDpk/hqdefault.jpg



My first Tutorial using a Blender 2.5 build. This is a very tricky technique, I am showing you there. It is used to generate a mask between two clipping objects. Later on I talk about how you can use that mask to create some nice glowing effects.

  1. Thank you so much, I just spent 4 hours trying to do exactly this with all sorts of complicated node setups. Finally changed my google search terms and found this, it's exactly what I needed.

  2. this is really cool and quite advanced with the compositing. I'm trying to figure out how to boolean away vertices, but boolean seems to only operate on lines and faces, not vertices. Not really interested in renders, just object manipulation. Thanks for the cool tut – I enjoyed watching.

  3. Interesting and Useful.
    I had some difficulties. Perhaps related to the warning at 05:42.
    I attempted to follow your instructions.
    I had some long text in a fibrous shape rather than globular monkey.
    I got glow in undesired invisible areas.
    I order to clean up the image 1. create a mask id node for the non plane objects (second id)..2. Blur that image to increase size 3. Multiply again the glowing areas to remove the partial defect. 4. continue to test
    Did I do something wrong?

  4. @mikh3x4 sure, that's possible, too. But the boolean modifier often behaves bugy. Or has this changed in newer Blender versions? I haven't tried it in a long time…

    Anyway: With this technique, complex meshes don't slow down the animation process as much as with boolean modifiers and you can have as much clipping objects as you want.

  5. As german as can be, but only because you ask 🙂 And, as mentioned before, screw it. This is harder to lose than learning the techniques you generously present to us, and doing sometihng like that in a foreign language deserves due respect, as doing this for others in general. Awesome videos, subscriiiibe!

  6. @dodgydavec I thought I was the only one. Have you seen Sebastian's tut on Blender compositing over at cmiVFX? Over five hours and he also uses masks extensively and explains them well. But for me it is most challenging to understand when to Mix with multiply or add or alpha over plus the masking.

  7. You still have your german accent.

    One matter of practicality. Tricky techniques don't need handholding. We can setup on our own. Make your life easier and skim the basic stuff.
