I've had this set in my runtime for awhile and finally have a scene I want to use the curtains in.  The default is a kinda blueish shantung and not what I have in mind.  I'd like to use the damask or velvets or silks.  I've tried just selecting the curtains and applying the material from the materials tab, but it doesn't change anything.  I have them parented to a wall section.

I'm using Poser Pro 2010. 

Have your tried refreshing the textures?

This is MT5 file, you have to be in Material Room also to apply from Material Tab.

With MC6, you can sometime apply from Pose room if material zone can be located.

Oh thank you, Medzinatar. didn't know you had to use the tab in the room.  wow.  Okay, now to try this again.

I feel so challenged sometimes.. lol

The MT5 is older type and only contain one material, so a material zone must be selected.  You can apply to any one zone you choose.

MC6 is newer and is collection of materials.  I find so far most can be applied to things in pose room even by drag and drop.

Oh wow, yes, that is sooooo much better!  dances

Now I have something new to play with  :)  Thank you, thank you!

As noted, Mc6 can be clicked because they have material names in them - they automatically pick what material - all you need is a current figure.

Mt5 must be dragged if you are not in the material room. Dragging over some polygon then identifies what material zone you want to load the shader into.

But - while in the material room, dragging is optional - simple double click or clicking load button is fine there, because when you are in the material room, there is a "current material". While in the mat room, dragging into the preview window allows loading into something other than the current material.
