Posterize Time and Blend Modes not working on pre comp

I want to pull my hair out. I have a pre-comp with 2D assets with a variety of blendmodes. Their transform values are being animated. I want these layers to move at a lower framerate (15 fps). The master / top level comp is at 30 fps. Posterize time does not affect their transform, so I've precomposed them. Blending modes break when pre-composed, so I enable collapse transformations. I apply posterize time to the child comp, and it breaks a bunch of the blends again, in a different way. So I turn on 3D as well, and now the blends work, but posterize time does not. I try to force the comp to have 15fps with "preserve framerate" enabled, and it works while inside the comp, but then I return to any parent and... nope. Still plays back at 30fps.

 

No matter what I try, it seems you cannot have posterize time/adjusted frame rates, 2D assets, and blend modes play nice together. What am I missing here? What can I try?

 

Thank you for any help.

Hi @Sage G.C.,

Try enabling Time Remapping (Layer > Time > Enable Time Remapping) and use this expression on the pre-comp's Time Remap property:

posterizeTime(8);
value;

 You shouldn't need to make the pre-comp 3D with this method. The collapse of transformation does bypass both the Preserve Framerate preference and Posterize Time effect, but this should allow you to apply the same framerate reduction while retaining the blend modes in the containing comp.

SUCCESS! Oh what relief, that did the trick. Thank you so much, John.
