Does a scene deteriorate?
in The Commons
I have set up many scenes and found that as I work on them Daz slows down, responds more slowly. Does the system gather "crud" as it goes along?
Do mats deteriorate during use? Gloss seems to me to become more difficult to set at I develop the scene.
It sounds mad, but that is the way it seems to me.
Has anyone else found that?

Well, from my experience, it's a good thing to just save and reload a scene you are working on every once in a while. If you are working a lot with materials, or load and delete clothing, characters, etc., then the cache sometimes doesn't clean up properly, and your system runs out of memory.
I know performance deteriorates as you add more polygons to a scene. A really complex scene can be a beast to try to edit.
Is there a way of clearing the cache without completely closing out DS?
Yeah, that's just Daz filling up your memory and cache as you add more stuff. So the scene is not deteriorating, its your PC's performance. BeeMKay's advise is sound. Save your scene often, and if it seems like things are slowing down, save and exit and try restarting Daz.
Are you using the iray preview in your work space? That can work your system hard if you don't have a really high end PC. Use it sparingly or instead run a quick low rez render to check how things are shaping up.
Leaving renders open uses memory, so close any you don't need for reference or that you aren't (for Iray) going to resume.
If you look in \Scripts\Utilities\ in Content Library under DAZ Studio Formats>default content directory you should see a Purge Memory script.
Thanks, Richard!
Thank you for your comments.
I understand much of this is the pc.
On a similar note, I always save my scene, close DAZ Studio completely, and reopen before I do a big render. It seems to speed up my renders often.
