Is there a tutorial how to set up dynamic hair in Iclone?
Someone made this in Iclone and the hair is pretty good.
Are the secondary animation on the hair created with bones set to dynamic items in Iclone?
I've quickly browsed through youtube but haven't found one yet

with softcloth - the concept is very simple - i'll try and explain it in a paragraph, from your other posts you sound experienced, so this may work ( for now till a video is made )
attach hair prop to avatar. enable your avatar to do collision. ( button on the panel, you enable the bones ) - Then enable the hair prop to be soft cloth enabled. From there it will ask you for a weight map - now with weight maps, if you pulled your model into sculptris and manually painted a texture - everything you paint black isn't affected by the soft cloth physics, everything white is max - everything in between are shades of gray. The very top of your avatars head would be black, then just below the temples, would start fading to a lighter gray. In the panel itself, there are a bunch of presets for hair - wavy, curly, long etc ....select the most appropriate one for the hair style you are using, and it will auto tweak the settings below those options. - basically on the weightmap, you can use the black color strategically to pin your prop.
there are other ways to achieve this with bones and springs as well, but the above technique is the latest one trending.

Thanks planetstardragon. Surpising its hard to find a video that deals specifically with hair dynamics.
I've been reading through the forumand just wanted to put these useful infos in this thread also for my reference.

Looks like 3dmax selection sets are directly supported. I hope 3dxchange supports lightwave or modo selection sets because its a weekend and I only have lightwave and modo at home. Its mentioned only pipeline version supports custom rigs and pinning but will verify if pro works. Note: The weightmaps in Iclone seem to be black and white image not actual vertex weightmaps.

Spring dynamics for bones tutorial at the buttom. Useful for polygona hair.
Some more useful info

oh, one more thing, if you don't see a collision option available for your character, you have to change the project from bullet to physx to enable it.

iClone 6 has switched to PhysX, whereas iClone 5 was Bullet for physics. The Bullet physics engine makes use of selection sets. The PhysX engine uses grayscale maps.
3DXchange Pro is all you need for rigged character import. Pipeline is only needed for rigged character export.
Softcloth clothing is better off starting out rigged to the skeleton, but hair need only have the proper grayscale map and be attached to the characters head. Simple clothing, like a skirt, also neednt be rigged. It can just be mapped black at the top and attached to the character's hips.

Thanks guys. So I should completely ignore the bullet physics videos on this page.

I assume there's no hair plugin for iclone and everyone uses polyhair on those hair video I posted in vimeo? No sasquatch, ornatrix plugin in iclone.
Hmm...accessories and props in iclone. New concept for me.

What is the difference when people mention hair accessory and prop items?
Dynamic hair is prop or accessory?

Some more research
Two very useful tutorials applicable for hair.
The hair is parented to the character as seen in the scene graph, and painted a weightmap with black at the root of the hair to hold it in place similar to a selection set.
Picking the character we can see under modify, the collision shape editor that makes dummy collision objects to interact with the dynamic hair or cloth. No option for convex hull though.

Thanks for starting this tread hattori. Thanks too, for the last set of links. It can be tough to search for information on the forum here. A lot of times you get results, but only for iClone4 or 5. I guess with iClone6 just being out, there will be a lot of tutorials yet to come.

No problem! Its good to have documentation collected for newbies like myself to reference while learning a new app. Trick I learned dealing with multi app pipeline is to always keep references.
Here's another one related to basic hair creation with 3dmax. Its applicable to any app like lightwave, modo, etc. Fundamentals are the same.

Hi guys, my name is James and I've been using iclone 5 for five years and in that time have had a real blast with it!! However, a problem has occurred recently where the hair disappears from my avatars heads. It appears to be when moving the camera to the left or right, and the hair stays on until the character passes out of frame with just a second to spare ( still enough time for viewers to see the bald head appear ). If I use the follow cams it doesn't happen ( more stable algorithm or just a bug maybe?!!) I can just work around it but I it means I can only pull the camera in or out from a character to a certain point before they lose their hair. Has anyone else ever encountered this before? I have been importing my characters in to iclone 7, through 3d exchange 7, as 3d exchange 4 and 5 don't appear to work properly with 5, with one telling me it can't work on windows 8.1 and 5 exports props but iclone doesn't load them ( anybody got any ideas there?!!! ) going back to the hair issue, I've noticed this hair issue is present in the avatars whilst in 7.so i figured it was probably a bug. If anyone has any ideas on this I would love to resolve it. Or I will have to find another way to add hair to my characters!!!! Thank you

I don't have iClone 5 on my machine, but I tried with an IC 5 character (Gwynn), and I don't see the problem. It is in a specific project or does it always happen?
One culprit could be the driver of your graphics card. What card do you have, and what are your other system specs?

Hi, Nvidia GeForce 770 with 4gb VRAM . ASUS mobo with 16 GB of .DDR3. DX11 enabled. I have used hair from other avatars outside my version of iclone and this doesn't happen, in fact I can get closer and tighter shots without the hair moving at all. I think it may be related to a bug in my version of Iclone 5. It happens in most of my projects, to some degree. I even tried converting the hair to. Prop but there doesn't appear to be that option. I wonder if it might be related to the key framing of the camera, perhaps it requires a more stable algorithm?? I am going to try linking the camera to a primitive, and basically attaching to an object to inherit the movement of that object. It's a minor issue really when one considers the scope and possibilities inside iclone, and if it means designing some hairstyles to then apply as props, I'm sure I can achieve that!!!! Thanks again sir.
