Doohickey, is that like the thingummyjig or more like the whatchamicallem?
I am pretty sure it’s more like a whatchamicallem than a thingummyjig.
I suppose in a way Decimator would help render a little quicker due the memory saving due to a low mesh resolution. I use it mainly to fit more than 3 Gen4 figure in a scene as I only have a 32bit system and 3 GB of Ram.
If you are intending to buy it then all you need to do is put in the serial number, in the Plug-in window, for Decimator as it should already be installed with DS4 Pro, it just needs activating.
