This is a figure I'm trying to build as part of an interactive anatomy textbook. I built a model of the cochlea (inner ear) in 3DS form, and inserted two of them inside a P4Fem head, hoping to illustrate how the cochlea is oriented on each side. When I made the head and hair partly transparent (using the Ctrl-U dialog box) here's what happened. You can tell from the shirt as well as the general shape of things, that the view is roughly left-rear. But the ears have migrated to odd positions, and the eyeballs face backwards! Scary! I didn't modify anything besides transparency, and everything is at standard scale, zero translation, zero rotation. This is a full render, not preview. There's probably no solution, but I wonder if anybody has seen this before?

Did you set the cochlea's parent to be the head? Just a thought.

You might fix some of the problems by making a second texture map without some features for the see-thru render (same pose for the opaque and see-thru renders). Or make one with just the skin texture so nothing else shows through and render and composite a cut-away ear section over the opaque render of the full head in Photoshop.

Or, you can do this: Pose your figure in the default position, and select "figure style" from the icon menu (default says "document style"), then choose from one of the wireframe styles, or hidden line. Select your background and foreground colors to create the greatest contrast and visibility for your figure. Place your cochleas where they should be, parent them to the head(do not apply bends!), and lock actors. You should now be able to pose your figure without the props moving about, and you should be able to see them through the wire frame. Skip the hair. It'll just get in your way.

The wireframe idea is a stroke of genius! That's how I'll do it. Tremendous thanks!!!!!

NP Be sure to post a pic to let us know how it turns out. >^_^<

Thank you, and here's your change!

Glad to be of service sir >^_~
