Raven here with the friendly reminder of the day. You can run multiple instances of DAZ Studio with a simple trick. Simply create a new shortcut for the studio and right click to it, go to ''Shortcut'' tab and add " -instanceName "MyInstance2" with the (")'s. It should look like "C:\Program Files\DAZ 3D\DAZStudio4\DAZStudio.exe" -instanceName "MyInstance2" and you can basically change MyInstance2 to anything you like.
I am currently rocking 3 instances simultaneously. Just be careful with the iRay. Turn it off for the inactive instances or you'll encounter vRam shortage. Another tip for the multi instance thingy, you will have to add the content directories from scratch because each new instance is a brand new one without the knowledge of your previous adjustments. Adding an image with the setup for convenience. Have fun.
