Hi everyone! Let me know if you have any questions about the mask modifier in the comments below! :)

Here is a strange but true situation. Tonight I'm making an animation where I need to do a break out view and I was going to try and animate the material transparency.. Opened blender, saw that you had a new video, decided to watch it before I start my animation and hey, this tutorial was just perfect! Thanks! keep up the great vids.

[HeinerS]

Perfect, just what I need for my current project (a building with some details inside). Now I can pull back the roof and show the details. As beginner I really appreciate such videos, so thank you for making them.

[HinnerkHesse]

I really like your calm voice and accesible way of explaining! It is both relaxing and interesting.

OMG! The method I've been using is to export an animation from After Effects (an animated mask) and then setting it all up to mask using shaders. This method looks much easier!

That's what you get for skimping on watching CG Essentials vids folks! Pain and frustration!
Oh wait, he only uploaded this yesterday... I can blame him then.

[mind_of_a_darkhorse]

This would come in handy for animating a light saber turning on/off.

[leonciocastillo]

Thank you so much for your help with this tutorial.

How would you do a doorway to another scene (like the doors in Monsters, inc.). I had assumed you would use a mask modifier.

[colepat]

is there a way to fill the face as it's masked away? so it looks like a solid object vanishing? does that make sense?

[BenLe]

AH The reverse button on the modifier That's what was causing the problem I had hoped to learn about here. Thanks

[HdudHeydh]

Where can I get the smooth option? I don't have it built in.

[jonnerjuandasihombing]

Assume I have a walking character. Instead of using 3d background, I just using a picture background like classroom contain chairs or table. So how I hide some leg or body of the characters? when we imagine he walks behind the table. Sorry for my bad English

When i click draw under weight paint I do not have the options that come up on your screen. Nothing happens. Nothing paints. Blender freezes when trying to paint.
