Blur effect in precomp do not work in main comp when masking

[simo5D2D]

Hello community,

I run into awful problem. I have some effects (like gaussian blur) on my animation, which is in pre-comp. The 3D-animation did not work in main-comp, so I skipped it. But its got text animation on it which I cannot skip. I need to reveal the pre-comp-animation in main-comp, by using masking. The problem is, the pre-comps FXs (like the blur) do not work in main-comp when I create a mask. The FXs disappear. And they reappear when I delete the mask. I need to do the masking in main-comp. I´ve tried shape layer masking and layer masking (and inverting), and it doesn´t matter if the layer mask is on "add" or "subtract". Nothing seems to get me around this problem.

There has been plenty of trouble already and this is my "plan C", or "plan D" already. I´m running out of plans. For some reason the link between main-comp and pre-comp does not work propely. Please, does anyone know, why effects won´t work with mask and is there any alternative solution?? Thank you.

Turn off the collapse transformations switch. I would suggest you study up on how layer switches affect rendering order and all that. For anything else screenshots would be more useful than even the most verbose descriptions.

Thank you Mylenium for the reply.

Unfortunately I cannot turn off the collapse transformations switch in main-comp, because it turns off the pre-comps FX in the main-comp. The same issue is with the masking in main-comp. It too turns off the pre-comps FX in main-comp. I got to talk to one AE-pro about this problem and he said it´s gotta be due to a bug. This isn´t supposed to happen. I have 18.1 AE version, which had bugs according to him. I´m still working with this old version, cause I have to be cautious due to my quite old computer. Adobe apps newer versions keep demanding more juice out of PCs, you know. However, I´m at "plan D" now, because of the time table. Anyways, thank you for the input!
