the spring principle works with bones.
For the hair, it is difficult to create bone chains for each strand of hair. This is why we use a physical mechanics that applies directly to polygons.

just wanted to add .... the horse animation you can edit the  spring of the tail... it would be great if you could do  this for clothes to.

Thanks Pixtim for your fast reply, it is golden info that helps broaden my 3d brain power.. I'm wondering with iclone software and an iclone character can I  change hair from soft cloth to spring effect so it will have extended bone already mapped in it? I'm guessing soft cloth is the newer of the 2 effects so it should be simple.... ish..

Hello,

Transferring animations with alembic format to Unity is not a good idea, the generated weights are much too heavy.

I think the right way is to transfer animations to FBX format and re-implement physical dynamics weight maps to use Unity's physical engine on clothing and hair.

Iclone uses black and white bitmap files as weight maps. There is the possibility to save them as an independent file.


That's what I'm doing now when I have to integrate character animations into my Cinema4D software. The problem I had was that the Cinema4D physics engine uses vertex maps and not bitmaps. I had to find a plug'in to convert bitmap to vertex map.
But now it works very well. It's adaptable and lightweight.

It's been a while since I'm using Unity anymore, so I will not be able to tell you the way. I do not know if it uses vertex map or bitmap.
But I think it's on this side that you have to look for a good method ...

Hello, I'm wondering if I use the avatar toolkit could I add bone to any prop/obj? I plan to be using iclone  long term so making use of everything is the plan. there is a tail in avatar toolkit with spring effects which is awesome to replace a ponytail. but prefer not to mod the hair mesh. thanks 

if the main objective its only render your animation inside unity you can export your character with softcloth in alembic and load it inside unity

Hi,

How to carry the hair animation form IClone 7 to Unity?
Alternatively, if there is no way, how to rig the hair adding bone/s to it so I could animate it in Unity?

*I have Iclone 7, Exchange Pipeline 7
