You can get really good color correction for your films using the LUT Filter Effects.

I have noticed that some filter effects (or a combination of them) change the way certain PopcornFX effects look. Take fire for instance, sometimes the filters can eliminate the smoke from the fire altogether and change the fire's coloring. In some cases, you want that, but in other cases, it would be awesome if we could keep the PopcornFX from being applied to the LUT Filters.

So my suggestion is to add a checkbox to PopcornFX (and other effects) that allow us to set whether the effects (and any sub-parts of those effects) are affected by LUT Filters or not.
