This is something that I think XL4 will really help with. You can "import" your LOR effect as a layer to use as an initial base. Then, slowly overlay it with appropriate or equivalent effects.
The really good thing about XL4 compared to XL3 is that the "Play Model" ability in XL4 plays the actual underlying rendered data. In XL3, it would "live render" each effect as it went down the grid. Thus, stuff that was already in the xseq file didn't get played. In XL4, because it's playing the actual data, anything already in the fseq (like from the layers) does play.
I just discovered this advantage this weekend (and I'm the one that wrote the new play routines so just discovering this now is kind of ironic). Much of my sequencing is done in HLS. With XL3, I could see the whole thing running on the Preview screen (I have models defined for everything I sequence in HLS). However, on the Nutcracker tab, I could only see the stuff I was "adding" to the sequence. With XL4, I hit "play" for my models and I got to see the HLS effects for that model along with the effects I added. Very cool.
