[Closed] Custom Attributes | FBX Export Problem

Hi everyone,

I’m currently working on a Scripted Custom Attribute (CA) with 3ds Max 2017 to export auxiliary data into Unity3D via FBX. My CA has 3 rollouts and 3 associated parameters blocks. I exported the object with the CA with FBX Plug-in version: 2017.0.1 Release (241562) (in ASCII mode), but when I open the FBX in NotePad++ only the variables of the FIRST parameters block get exported. This happens regardless of whether the CA is carried on an Attribute Holder or is part of the base object (in this case en EditablePoly).

Is this a known issue? How can I achieve an export of ALL parameter blocks?

Here is a snippet of my CA showing the 3 parameter blocks:

      parameters ParamsCPI rollout:CPI_RO
      (
        IsInteractable type:#boolean default:true
        CPIType type:#integer ui:CPI_Type_RBtn default:1
      )

      rollout CPI_RO "CP Interactable" rolledUp:false
      (
   ...
      )
   ...

      parameters ParamsStepped rollout:SteppedInteractable_RO
      (
        StateListBaseHeight type:#integer default:200
        SteppedRolloutBaseHeight type:#integer default:300
        SteppedRolloutMaxHeight type:#integer default:350
        IsSequential type:#boolean ui:IsSequential_CBox

        TotalCreatedStates type:#integer default:0
        StatesCount type:#integer default:0

        StateNames type:#stringTab tabSize:0 tabSizeVariable:true
        StateTitles type:#stringTab tabSize:0 tabSizeVariable:true
        StatePositions type:#point3Tab tabSize:0 tabSizeVariable:true
        StateRotations type:#point3Tab tabSize:0 tabSizeVariable:true
      )
            
     rollout SteppedInteractable_RO "Stepped Interactable" height:300 rolledUp:false
      (
   ...
      )
   ...
      parameters ParamsSmooth rollout:SmoothInteractable_RO
      (
        SmoothType type:#integer ui:CPI_SmoothType_RBtn
      )

      rollout SmoothInteractable_RO "Smooth Interactable" rolledUp:false
      (
   ...
      )

And this is the relevant snippet of the exported FBX file:

...
    }
    Model: 1892532272, "Model::Sphere001", "Mesh" {
        Version: 232

            P: "mr displacement parametric subdivision level", "Integer", "", "AU",5,5,5
            P: "IsInteractable", "Bool", "", "AU",1
            P: "CPIType", "Integer", "", "AU",1,1,1
            P: "MaxHandle", "int", "Integer", "UH",2
        }
        Shading: T
        Culling: "CullingOff"
    }
}

Many thanks for any help!
