I'm glad to hear that the model is working well.

Re filesize:
1. Removing the unused channels saves about 5% of the (stripped) cr2 filesize.
2. The big difference between Poser 4 and Poser 5 is the material code: In the
stripped cr2, the channel code is less than 20%, the material definitions are about 80%
of the cr2 (84 KB versus 460 KB).

To VK;

I noticed that on the Vespa, there are dials in the "body" that control the visiblity of the spare tire, and extra seat.
Would you please explain the procedure for accomplishing that?

The changing parts are "alternate geometry".

In the figureResFile, the geometry of actors "sparewheel" and "pillion" is a single tiny polygon "p_dummy" inside the Vespa body. The "p_dummy" geometry is invisible.

Code: [Download] [Hide] [Select]

actor sparewheel:1

    {

    storageOffset 0 0 0

    geomHandlerGeom 13 p_dummy    <---  tiny single polygon 

    }

actor pillion:1

    {

    storageOffset 0 0 0

    geomHandlerGeom 13 p_dummy  

    }

There are extra geometries for the pillion, the spare wheel, and the rack to mount the spare wheel.

In the respective actors, for example "pillion", there is an "alternateGeom" instruction to load the pillion geometry. There is also a "geomChan" channel which displays a dial to choose the alternate geometry.

Code: [Download] [Hide] [Select]

actor pillion:1

    {

    name    pillion

    on

    bend 0

    dynamicsLock        0

    hidden        0

    addToMenu    1

    castsShadow        1

    includeInDepthCue        1

    parent vespabody:1

    alternateGeom    pillion

        {

        name pillion

        objFile 1003 :Runtime:Geometries:vspscooter:pillion3.obj    <--- the alternate geometry

        }

    channels

        {

        geomChan pillion  <--- choose alternate geometry

            {

            uniqueInterp

            name (pillion)

            initValue 0

            hidden 1

            forceLimits 4

            min 0

            max 1

            trackingScale 0.045

            keys

                {

                static  1

                k  0  0

                }

            interpStyleLocked 1

            staticValue 0

            valueOpDeltaAdd   <---   ERC slave code

                Figure 1

                BODY:1

                vpvsp3pillion

            deltaAddDelta 1.000000

            }

        }

The geomChan channel is an ERC-slave of a master channel in BODY. When you set the master, the geomChan loads and displays the alternate geometry, for example the pillion.

Code: [Download] [Hide] [Select]

actor BODY:

    {

        {

        valueParm vpvsp3pillion    <--- ERC master

            {

            name Pillion

            initValue 0

            hidden 0

            forceLimits 4

            min 0

            max 1

            trackingScale 2

            keys

                {

                static  0

                k  0  0

                }

            interpStyleLocked 1

            }
