Hey Richard - I think Decimator is supposed to let you make a new Level Of Detail for mesh, say one at 50% of vertices or polygons, another at 25%, another at 10%, and then toggle the Mesh Resolution setting so you can go back and forth between the higher and lower resolution models. (just as you can do with V4, for instance, by toggling her mesh resolution between base and lower poly models.
Decimator in DAZ 4.5 is letting me decimate down to a low poly model, but even if I reset the model back to better resolution, no actual change takes place - I’m left with the low quality model. I’m also not seeing LOD’s added to the model - so if I reload it from browser, and go look at Resolotion options, the newly created LOD’s arent there.
I’ll have to recheck in DAZ 3 Advanced (at some point it was working properly there, don’t remember if any updates broke functionality or not.
