This is the Beta version
Scaling and translating the "it" node will make modeling very difficult so, for now avoid it!
With this new version of the plugin
The isosurface program places the responsibility of rendering the isosurface to Daz Studio
it does so by hijacking an existing object in your scene
the object must be renamed or rather relabeled "it"
and that's case sensitive
so ... create a primitive plane
re-label it "it" ( without quotation marks )
create your mcjIsoSurface4 using Daz Studio4.8's "Create" menu
proceed like you did with the old version
the instructions are here https://sites.google.com/site/mcasualsdazscripts/mcjisosurface
If you set the mcjIsosurface4 node visibility to off, the "it" shape will stop being updated
you would want to do that when you have many metaobjects in your scene
and want to position them without the slowness of the interactive mode
do not convert the "it" node to SubD - this will likely crash Daz Studio
