I thought i would check on here and see if anyone had any tips on how to speed up simulations. I am mainly doing static poses and not animations. Usually not much background scene going on. Sometimes the sims take a very long time. I know a way to speed up renders is to change the "Update interval" to like 2 minutes. wondering if there is something like that for simulations.
I will also mention that I use Daz3d for fun and just like to play around with it so i am not formally trained but do enjoy creating.
Make all the hair in the scene "not visible in simulation", except for the one you want to simulate.
Sometimes I've had to also make other things invisible in heavy scenes.
You can also pose your character and simulate the hair/clothes in an empty scene, and then save it as a Scene Subset and load it into your other scene.@frank22 is that more efficient than merely selecting what to simulate in the scene tab and right clicking on the simulation tab and using simulate selected?
Disabling smoothing before simulation can help too, then re-enable after, if necessary.
@Dick "...is that more efficient than..."
The idea is to hide the hair geometry in the scene when simulation is slow or fails. I will usually fix a failed to simulate situation.Good tip! @frank22
Thanks @Dick
Of course it's always better to simulate only one hair\clothing article one at a time. Maybe it's the dForce hair I use, or my GPU or just dumb luck that I usually get fast and reliable dForce simulations.Like Dick said, make sure smoothing is turned off on everything during the simulation, this is probably the biggest performance killer.
If you ever use "Point At" for things like eyes and need to "Start from memorized pose" then set all "Point At" to none. Also don't use "Start from memorized pose" if you don't have to, try running a simulation without it first, if the items falls the way you'd like then this will save a bunch of time.
If you've had Daz open for a little while and have run a bunch of simulations/renders then the dForce simulation might start to bog down, closing/reopening Daz can fix this.
Last is using Fit Control (for clothing) and Mesh Grabber. Often dForce won't work exactly the way you want so using those addons can be far quicker to fix/adjust a simulation instead of running it multiple times and hoping it ends up the way you want.
