Hi folks - does anyone know how to obtain variable transparency using a transparency map? I want to make an object have an almost transparent area, say the top half of an egg, which gradually gives way way to a solid material further down.  I tried using a grey-scale tranparency map, but the results make me think Poser can only handle black/white i.e. transparent/solid with no in-between stages.  Any ideas?

Care to share your discovery? It might end up being very useful to know. :)

Poser can handle a gradient. Just make sure you set the gamma correction of the transmap to 1.0 if you use Gamma in your render settings

Patience!  Still working on it!

Pug the Image_Map for the transparency into the the 'Transparency' input of the Poser Surface.

Here a Poser one sided square has a transparency map applied to it. This is PP2012, but I think it should work the same in your P7 or P2010.

Cheers Les, busy perfecting it as I type!

Here's the effect I wanted, I cut a window, which is still specular and not fully transparent with soft edges in V4's skull, added non-transparent veins across it.  The base material is an SSS blue jade.  Inside the skull is a brain-type object, but it could be biomechanical.

Now for some Geiger-esque fun!  This is only a very rough test.

some trans mask fx may also be achieved with UV variable nodes et al.
