Okay, I'm going through the process of describing the problem to SM, right? Actually went through the process with a fresh V4 and did the following steps:

**Steps taken:
**
Load Victoria 4.2 by Daz3D into a Pz3 scene in Poser 7, SR3
Add morphs and textures
Save this scene (Pz3)
**Victoria 4.2 figure material list in the material room is as follows, and in this order:
**
4_InnerMouth
4_Gums
4_Teeth
4_Tongue
2_SkinHead
2_SkinNeck
2_SkinTorso
2_Nipple
3_SkinArm
3_SkinFoot
3_SkinForearm
3_SkinHand
3_SkinLeg
6_Eyelash
3_Fingernail
3_Toenail
5_Cornea
5_Sclera
7_EyeSurface
5_Iris
5_Pupil
5_Lacrimal
7_Tear
1_EyeSocket
1_SkinFace
1_Lip
1_Nostril
1_Eyebrow
**
Load this scene into Poser 8, SR1
Make some modifications (add a hair figure, change the pose), save scene in Poser 8
Check in the material room... the material list fot the Victoria 4.2 object is as outlined above
**
Re-open that scene in Poser 7
Select the Victoria 4.2 figure and go into the material room
For the Victoria 4.2 Object, her Materials list is now in the following order:

And Now It Doesn't DO it!!!!! grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr

The order is fine. No different to what it's meant to be. BUT IT DID this BEFORE... I have Pz3s to prove it.

Needless to say, no email to support. Can't reproduce the problem. Sorry to have taken up everyone's time with this when you could be learning more about shadows and lights and IDL...
