Does anyone have any tips on revealing a mask?
Hi there
I know its been asked before but Ive never really got it properly! Basically I have a solid that I have created a mask on of a rollercoaster, I want the rollercoaster to come out and appear using the mask but the only way I know is using the linear wipe transition that just brings it on or using another mask to bring it on but they both are just like wipes. Is the only way by keyframing the mask shape every couple of frames? Are there any other effects I can use so it kind of curves out more than just straight linear?
Thanks in advance!

Hey,
Yes, maybe try this little tutorial to get the hang of it:
1. Create a comp
2. add a solid layer
3. hit ‘q’, drag out a mask on your layer in the comp window
4. hit ‘m’ to twirl down the mask on the solid layer
5. click on the Mask shape stop watch to add a keyframe at the current time.
6. move your time cursor forward a few seconds
7. click on Mask 1 in the solid layer to activate the mask
8. go to layer>mask>free transform points, you will see a bounding box around your mask in the comp window.
9. hit ‘v’, drag out one of the sides of the mask’s bounding box, this will add another keyframe in Mask Shape.
10. ram preview…you should see the mask edge move over time.Take care,

Hey,
Duh, I misread your post…sounds like you know how to a simple reveal, you’re looking to do more complex stuff…
I think what you’re looking to do is add points to your mask, you can do this with the pen tool…you add points to the existing mask (or draw out a totally new one), then move your cursor forward and add/remove points or move them around. In the pro bundle (anyone, correct me if i’m wrong) you can set two mask shape keyframes and AE will do some ‘smart interpolation’ in the mask morphing, I haven’t yet used that so I cannot speak for it.
Take care,
Nick

Hey there
Thanks for your help, thats kind of what Ive been trying but it gets a bit complicated because if you start deleting points and making new ones the interpolation can go a bit crazy. We will see!
cheers
