Okay, I got my HLS sequences converted to XL after some help from Boof (thanks mate), but now I'm struggling to remove some effects/data layer from some of my models. I was advised to add/overwrite with an effect at at the model level and this would overwrite the data at node level. I could then delete the effect, which would remove the effect/data layer. I did this, but the data layer keeps re-appearing. It doesn't seem to matter what I do, it returns. I have tried on a number of sequences, and the same thing happens. Any suggestions?
