Anybody know’s how we can access Hair and Fur modifier and it’s properties by using c# and Autodesk.max assembly?

I guess like other World-Space modifiers…
Hair & Fur class ID is #(148282010, 473681766).
But I never have tryed it (just done some Object-Space modifiers tests).

I searched the entire SDK and Autodesk.max, The only thing that I found (Max 2018 and above) is:
(C++) maxsdk\include\Scene\IHairModifier.h
(C#) Autodesk.Max.MaxSDK.IHairModifier
But it seems this class only return some basic info and is not a solution to set-get all data.
You mean something like this?
IGlobal global = GlobalInterface.Instance;
IInterface coreInterface = global.COREInterface;
IINode selectedNode = coreInterface.GetSelNode(0);
IObject objRef = selectedNode.ObjectRef;
IIDerivedObject derObj = (IIDerivedObject)objRef;
IModifier mod = derObj.Modifiers[0];
IIHairModifier hair = (IIHairModifier)mod;
// ?? ...

I’m not an expert at all, but I think that with ‘ObjectRef’ you only get the OSModifiers.
To get the WSModifiers, you have to use ‘WSMDerivedObject’:
IIDerivedObject derObj = selectedNode.WSMDerivedObject;
This derived object will hold all the WSModifiers applied to the node.
For Hair&Fur I get 87 parameters, 61 of which are animatable.
Hope it helps.

So complete code would be like this?
IGlobal global = GlobalInterface.Instance;
IInterface coreInterface = global.COREInterface;
IINode selectedNode = coreInterface.GetSelNode(0);
IObject objRef = selectedNode.ObjectRef;
IIDerivedObject derObj = selectedNode.WSMDerivedObject;
derObj.
Can you tell some of does parameters that are belong to the Hair?
The parameter that I’m trying to find and change (I hope exist) is the number of segments when I apply hair to the spline.

You have to get the IIDerivedObject modifier corresponding to Hair&Fur
IModifier tMod = derObj.GetModifier(i);
, get its IIParamBlock2
IIParamBlock2 param = tMod.GetParamBlock(0);
and then go through the parameters or subanims of the IIParamBlock2.
What I get is:
WSModifiers NumModifiers: 1
DerivedObject SubAnim[0] Name= Hair and Fur
Modifier[0]= Hair and Fur

Wow, Thank You!
I should test some of them to see which one is the parameter that I was looking for.
I’m just curious how you get (printed) this info. Do you have any utility for this?
