I can't working Cloth Dynamics working using object collision with bone active setting!!!

(It seem to Caculate with none bone deforming)

Someone help me please & Thans >~<

Some more detail might help us understand what you are trying to do. Do you have a softbody that a boned object is to interact? Are you trying to use softbody on a boned object? If the later you will need to use a weight map to assign the deformable areas - if the former it could be your order of deformations settings. Dan Ablan's new Lightwave 11.5 course might be of help getting up to speed.

Just trying to make a easy test like LW11.5 PDF menu ....a woman Bullet cloth effect

I want to understand why not workiing with moving bones" when I open the draw collision shape display option"....

the cloth just working in no deform object(maybe bullet dynamic deform not support bone system....i don't know)

Did you already try this? Directly from the 11.5 Manual addendum, page 83:

Using a Deforming object for Collision
When using a character or anything else deformed by bones, morphs or displacement as a
softbody collider, you need to transform the mesh itself (or part of it) into a Bullet Deforming body.
If you want to maintain the original shape of the deformed object, you need to set some
parameters in the Bullet Softbodies panel:
Shape Retention must be set to 100%
Shape Lock must be set to Translation & Rotation
Both Linear and Angular Stiffness must be set to 0
Volume Conservation must be set to 0.
Use simple kinematic shape objects parented to the bones of characters to create effective
softbody colliders. Capsules are perfect for this.

I had tried this,page91:

Bullet and Bones
You can now parent a Bullet-controlled kinematic object to a bone and animate the bone using IK,
targeting, etc. and the Bullet dynamics will read the motions

but not working ><

It working on moving object well....But not bone setting objects

Thanks! I change collision object bullet type Kinematic to Dforming & it works well
