Daz How can i save custom Surface Groups?

[Emoon]

EDIT: Nevermind, i'm just a dummy! I was so desperately looking for that "save Surface Groups" option that i didn't try to just save it as a regular scene file. Apparently saving it as scene preserves all changes to surface groups.

Hey all,

i'm trying to reduce the number of Surface Groups on my Gen8 model in oder to minimize draw calls later down the line.
Now i'd like to know how i can save them out so that i don't have to redo it every single time? But i can't figure out under what type i have to save it or if it's even possible to save custom surface sets.

Here is a screenshot of what i have so far.


Any help you can throw my way is highly appreciated!
Thanks in advanced and all the best to you.
