I've been experimenting with Poser's cloth room for a while (you have to be persistent) and I'm starting to understand the meaning of all the settings there, and  I'm also beginning to obtain incredible results. My probem is: it takes some time. For exmple, for a 720 frames shot, I have to wait like 4 hours! My question is: would a render farm help? I know render farms are for rendering, but can they be used for something like dynamic cloth?

Not in poser. Perhaps other ( and more expensive) 3D-programs have that option. The poser clothroom is not so fast as other programs like 3D-studio.
You could try to decrease you clothmesh density to improve the simulation time or change the simulation settings. I use poser 8 and poserpro with a core2 quad processor, and most of the time I have simulation times of about 5-8 seconds a frame.
When I have a simulation time of more than 30 seconds, I first try to change the simulation settings, especially the coliding objects should be set to a minimum: if you have a dynamic skirt, most of the time you only need the hips, the thighs and shins to colide. (or even less )
Don't forget to uncheck hair objects, which can be easily forgotten, or other objects in the scene you don't need.
If nothing else helps: decrease your meshdensity.
And I agree: dynamic cloths are wondefull.

Perhaps you can share your insights to the cloth rom via some tutorials. :biggrin:

Any place that the cloth will be "squeezed" between two colliding parts (like say the thighs, or the upper arm against the chest) will cause calculation time to go way, way up, and usually trash the mesh.  Try really hard to avoid these.  For example I've seen people try to have a G-string be dynamic, that's a real waste of time.

Cloth Room Tutorials and Bookmarks

Thanks Acadia. I know about the sticky.

I meant the OP as he/she has seen something in working the cloth room. What was the "A-ha!" moment?

The tric for the cloth room is to stay low poly, and avoid "useless" collitions.

What you can do is:

Make your clothing LOW RES, do the sim.

Export the "clothed obj", and only then subdivide when needed. For "stills".

Final adjustments can be made with the morph brush. (If needed.) 

For movies? ? ? Stay Low Poly.
It is the only real "speed improver."

Also, parent cylinders and spheres to the body parts the cloth collides with, and set the cloth to collide with the cylinders and spheres instead of the actual body parts. You may need to use a magnet or two on the magnets and spheres, but it will save a lot of time in the long run.

Quote - For movies? ? ? Stay Low Poly.It is the only real "speed improver."

It makes sense using low-poly cloth is going to improve the speed, but isn't it also going to defeat the very purpose of the cloth room? To make natural folds in the cloth, you need a fairly high-poly mesh; otherwise, the cloth will just remain rigid.

Actually not as much as you might think - Poser has polygon smoothing, and D|S has subdivision, so the final render will appear a lot more natural than the low poly base.  For D|S this might cause problems with trying to animate the whole simulation (don't know), but for Poser not at all.

As in my tutorial, I model very LOW Poly. Then let poser do the initial pushing into model and shape. Then detail the exported obj, perhaps subdevide one. Then go back to Poser, to let poser do a second pushing in the cloth room. Then we are very close. Look at what can be improved, the cloth should fit pretty well by now. And then let Poser do the final pushing. Always remember; some clothing will mostly be "skin tight clothing". Do that with a displacement map. (never breaks) Skirts have to "flow", and wrinkles need poly's. (but even these can be done with displacement if needed.

i often balance, between poly count and displacement map.
Mostly, the poly count stays low.

it gives a lot more opportinuties to improve on a lower poly mesh clothing, at a far less time.
Once the clothing fits the figure, it wil only see the occlusions of the moves. Arms and legs mostly.
So:
Keep skintight clothing in displacement maps.
Keep poly count low on area's that do not wrinkle.
Put details in the maps, diffuse, bump, and-or displacement.
or/ / /- - - - -
Do not use any clothing model at all!
See included picture made with the P4Lo Res figure.
ALL is modeled in the origional model.
And  some is in the displacement.

Only the model, only model and displacement, and the finished one.
 

And another one

Very interesting information about displacement mapping, Vilters. I'm not a modeler. But can you show us low-poly dynamic cloth with some folds and wrinkles that were processed with Poser's cloth room? I'd lke to see how low-poly wrinkles come out with your method.

I've also been messing with Poser 8's cloth room a bit but I had a serious crash (had to re-format and re-install Windows, and all other software including Poser) so I lost a whole bunch of examples I had. The best I can do is point you guys to a thread at DAZ Commons...
