Any way to always set Viewport to non-Iray on Launch or file Open?

Snuggins

I find that there can be a big delay if I quit Daz3D with the iRay preview on, or forget to turn it off before opening a new file or other operation that will require the card to load/purge a bunch of stuff. Rendering I am used to waiting for, but not paying the price of many minutes while each part of the scene is re-rendered just to be invalidated by the next object load, over and over.

Maybe this is more a support request or a call for me to learn some internals. But that will take longer than the load taking place right now as I type!

Theer is a script to set the drwa style of the active viewport here http://docs.daz3d.com/doku.php/public/software/dazstudio/4/referenceguide/scripting/api_reference/samples/specific_ui/active_viewport_drawstyle/start . You could have it go through all the viewports, instead of just the active one, and check to see if the current style was "NVIDIA Iray", then if it was set it to whatever default you want to use. Use Edit>Prefrences>Startup>Load File to run the script on launch and/or Edit>Preferences>Scene>Load File to run it on File>New.

A quick hack job, it seemed to work (famous last words):
