Is there a way to use dials to change the textures/transparencies in poser? I want to go from solid to not there, I was thinking of remapping the figure I am working on and make the part I want to disappear a separate obj but that will break the rest of the figure. Can anyone point me in the right direction?

I can't think of a way of doing it smoothly. You could use geometry switching to bring in differently UV mapped versions of the same mesh, and hence select different areas on a transmap - or maybe use different materials, each with its own transparency setting. The transparency resolution would be limited to the number of geometries you felt able to include and it could get unwieldy very quickly.

If this is for an animation, why not apply animated materials? You can simply animate the transparency value.

If you're not concerned with compatibility, P7 lets you animate the
Visibility state of a body part or figure.  Find the Visible checkbox
on the Properties panel of the body part, and turn the Animated key
to green.  Poser will then add a Visibility parameter dial to the part
or figure.  You can keyframe this dial like any other parameter.

Problem is with selecting the visibility of the body part will make the 90% of the figure disappear. It is a texture I need to make invisible not the part itself. I may have to redo the grouping and make that part a different Group which I was trying to avoid.

P5, P6 and P7 can animate material parameters, so with the right node setup (to properly handle all aspects of the material i.e. specular and diffusein addition to transparency), you can make any material become fully transparent under the control of a dial (i.e. keyframable).
If you wanted to have more than one material under the control of a single dial you'd need to rig some ERC between the individual dials.

I am unsure how to do ERCs.
But I have decided to take the route of using a transparency to hide the ceiling using a MAT Pose.
