Seems no matter how many frames for the simulation, it also chokes and stops somewhere along the line. Doing very simple tests with Jessi and her free miniskirt and top. Anyone else having these issues? Or am I doing something wrong?

I had similar problems with the scarf. I have not had time to figure out why or if I am doing something wrong.

This happens when the simulation gets confused. Often it is not obvious why it jammed up. Try retiming the animation to use more frames or use more drape frames at the beginning. Changing the cloth dynamic settings can help too. You will have to delete the simnulation and re-setup every thing. This is a bug in Poser. Once a simulation fails it will never work again. Don't forget to file a bug report at CL. Maybe they can get this fixed in SR1. Nerd3D

I had this problem many times in P5. So it's nothing new, just something they didn't seem to "fix". I'm also having trouble running dynamic hair simulations. The calc hangs and seems to take dramatically longer to achieve, when collisions are enabled, than it ever did in P5. Probably due to the memory problem. Hope they fix that soon.

Ok thanks. Still reading the manual on these things, but it's good to know I am not totally on crack

Hi :) I had the same problem and contacted CL , They told me that its not a bug , but the simulator is getting confused , and If in the pose/animation the cloth gets squashed between 2 body parts it will confuse the simulator and stop ,In my test I was using a walk cycle and when the arms swing past the chest the cloth was being squashed between the arms and chest , adjusting the arm swing so that the arms swing out a bit more fixed the problem :) i have noticed that when using it with poses it also happens that some body parts come in contact with other body parts in the transitions before the final pose , justing these contact areas so they give the cloth room to move has also fixed these situations:) I hope this Helps :) Cheers Senyac

Yes, you can also constrain the vertexes under the arms to prevent the simulation from getting stuck.

The "bug" is that after you correct the pose you can not re-calculate the simulation. The scene is corrupted. You must delete the simulation and recreate it. Yes, save right before you run a cloth sim, every time I forget to I regret it.

I also offer a freebie cloth helper on my website. It is a low-polygon set of mittens and booties that you can poot on your figures hands ane feet to help keep them form getting tangled in the cloth.

Cloth Helper, you'll need to register to download the freebies.

What a useful thread! Thanks for the info. I've been frustrated with P5 cloth simulation over recent weeks and the silent failure due to pinching between body parts appears to be the cause. A pity that the simulator can't give a reason for the failure or indicate the problem areas as happens with collision detection body parts. One question I'd like to resolve is what are the vertex contraints relative to? the body part that the prop is parented to?

The closest collision object is where the constrained vertexes are attached. Nerd3D

Question answered. Thanks senyac. Nice image BTW.

I notice that apart from the front of the thigh, none of the rest of the dress is particularly in danger of pinching by body part intersection. My cloth is getting caught up in the crossfire between bend and side-side motion of the buttock in the groin area, with very acute angles and subtle but definite pinching in the middle of a walk cycle. I'll try constraining some of the vertices to the inside of the thigh and see if that helps. OTOH, I guess the effort to create joint controlled morphs to avoid the body part intersection isn't completely wasted.

With your close fittng shorts you only need to constrain the vertexs around the top of the shorts(around the belt area) the rest of the shorts and the legs of the shorts should follow the corresponding legs :)If you have trouble with the cloth between the legs stuffing up you could try constraining those areas to the inside of the legs , some times it takes some trial and error :)

Another tick with pants that are dynamic. pull them down in the groin area a bit. It keeps them out of the trouble area between the hip-buttock-thigh area. Nerd3D

Thanks nerd, but baggy hotpants aren't my style ;-) Good tip though.

AHHHHH now i have got the same problem and it happened in P5 and now in P6, i converted the Spycoat for the GIRL to a dynamic cloth and wanted a walk cycle but as soon as she started to walk the whole thing stops, Every time, i think the cloth is getting stuck behind the knee joint, and the cloth is parented to the chest, because the coat splits just below the breasts. Is there a way to keep the cloth from being pinched by these joints or is my animation DOOMED???????????

Parent a sphere to the end of the thigh and scale it to "protect" the problem area. Add it to the collision objects and calculate. Hide or delete the sphere before rendering. Nerd3D

Hi:) Shedofjoy :) In your case adjusting the legs or knees would most likely stuff up your walk cycle :( So I would try placing a wind force in to blow the cloth away from the knees stightly , you will have to play around with the settings to get what you want:) I hope this Helps :) Senyac

Thanks Senyac, that idea hadn't crossed my mind, i will give the wind idea a go, as for a Sphere hidden around the hips, hmmm this doesnt stop the knees from causeing probs. Thanks anyway
