baffled on masking

[stevesbro13]

I have tried every tutorial online. I have searched the forum here. I cannot get my layers to mask. I put the tutorial video on as I try it but nothing is working. When I check hide all, mask layer, add to mask and all of that, nothing happens. There is no masking effect taking place. Can someone please help? Is is possible that there are some sort of presets on anything else that are turned on/off that I need fix. I am desperate and have exhausted all options.

have you got something like:

group: masking: Hide all -- to show what's covered by the mask
>> vec 1 the layer to mask: "mask this layer"
>> vec 2 the mask: add to mask but keep invisible (if not "keep invisible" then you'll just see the masking shape)

or

group: masking: Reveal all -- to show what's not "covered" by the mask
>> vec 1 the layer to mask: "mask this layer"
>> vec 2 the mask: subtract from mask




is it still wrong when you render?

ok I can see it when I render it. Thank you. I'm wondering now why I can't see the effect before rendering.

You should be able to see the masking effect in the normal workspace for most situations. Where it usually fails is with multiple nesting of masks for a single Group. Usually, you can work around this by making separate masking groups for each element instead of trying to use one masking group for everything. But even with complex nesting situations, ASP usually renders the masks correctly.

Just wondering, have you tried disabling GPU Acceleration from Display Quality? I usually leave it switched off, especially when I see display problem like this. On some systems, you may also need to disable Enable GPU from Preferences, but usually just disabling it from Display Quality should do the trick.
