Hey guys …
I’m wondering if anyone has a few tips and tricks for optimizing your simulations during the iterative process …
I’m adjusting the properites of my aritsan maps (specifically the wrinkle map) and gauging that against a simple animation driving the solution …
But clearing the cache and resiming is killing me …
I’m using a lowres mesh (3000 faces) with the intention of uprezzing once I get the motion and creasing that I like …
Any thoughts?
i do things like
first sim the cloth without any collisions turned on or
hooked up, including self collision
use nail constraint to hold a piece of the cloth in place
as if you were holding it with your fingers
sim it for a few seconds , see how it reacts, is it too heavy or light,
etc… also how much it bounces or stretches / retracts
I have scripts that help me dial in solver attrs
use show stress to see if any verts are having a hard time.
This is usually due to an unshared edge in your poly shape.
(a vert(s) need to be welded and the cloth re made)
once I kinda like the cloth behavior without any collisions,
I’ll try a pass or two with self collision on,
then I connect it to colliders and and sim it on a rather
simple animation, like a walk cycle, and a more agro cycle
like a run cycle. I add constraints, mimic, pin , colliders, forces, etc…
durring this point I do all of the solving in batch mode
creating a new file for every change in syflex settings
I run these batch solves thru a script that does a few things;
it sets all solver cache attrs to a new directory based off of
the file name, forces a solve and renders every frame.
I have a little system so I need not open maya in gui mode
to adjust the syflex settings.
Sweet … thanks man …
I got my sim down from two minutes a frame to about 25 seconds …
Just cleaned out things like non-manifolds, lamina faces, etc.
I also carefully scanned over my hypergraph and found that I’d attached a smoothing node after the solver … doh!
Thanks for the workflow suggestions!
