masking issue

I'll reiterate my post above: we can make a million guesses about the cause, but if you press UU to reveal all changed properties on the problem layer, then post a screengrab of the whole screen, it will be far easier to diagnose.

Are you using any effect on the same layer? Some filters like Corner Pin or Power Pin (and some other) can cause the mask to not properly shown when masking (remember that AE renders masks, then effects).

Also, please provide a complete screengrab rather than a cropped one, preferably with the Mask parameters visible on the problem layer, so we can see the full UI.

Hi Kibe5EB7,

Thanks for writing in.

Would you mind sharing more details on what's happening so that we can understand and troubleshoot the issue properly?

We're here to help, just need more info.

Thanks,

Nishu
