well i don't know if any of the following info is of any use to anyone here or not, but i thought i would just share my experience and the fix that worked for me,

now i ain't too tech savvy so you'll have to work out the techy reasons for it yourselves, but..

i had a similar problem to fixer when placing an RM texture to my character, and importing that into vue 7 inf, since i last posted here, but instead of green i had an almost black, as though the sun light were behind the figure instead of in front,

two observations then followed,

one, looking at RMs shader structure, i notice she is using a method i haven't seen before, all nodes are attached to a single texture node as oppossed to the default node, with various first step input nodes coming off of that as you would normally see.
 
her nodes look very impressive, but as i don't have P7 i don't know if that is how the nodes structure now, or whether that is an exclusive structure she has made.

second observation was that the only thing i had done in between using her tex on her character ( which worked )and using her tex on my character ( which didn't work ) is that i had had a look at some of the sample scenes on the extra content disk.

which makes me wonder if by simply opening the sample scenes, which i will guess were all made on the first build version of vue, onto my latest build version of vue, whether that could possibly revert any of my personalized settings to the settings of the user who's scene i have just looked at, and whether if i then went to load my character into a scene, it is now loading my scene with the settings of that user...........( i aint tech savvy so don't know)

so i first revert all my setting to default from the options menu, that doesn't work.

next i notice the way i import into vue, which has me selecting NO for reposing in vue and YES for using poser shaders in vue, warning window pops up and i click on the get on with it option.

texture doesn't look right with whatever GR, GI, or AO atmos i load, but i notice a running red man where my mats are normally shown at the top of vue, i double click on him to edit, in there i click on " simple material",then click ok,  then the texture ( for that part) is now showing up correctly when i test render, i carried on to do that with all the mat parts and that was one way of fixing it, but then i found a one click option that  also fixed for me...

this time when i imported my pz3 i selected NO for reposing and NO for posers shaders, no warning window this time, and no texture errors either all came in correct......vince sits wishing he had tried this way before the other way but both worked and fixed it for Vince.

if it works for anyone else then bonus.

i officially retract my wavey finger of blame that so recently was pointing towards poser makers, give it a fancy gunslinger twirl and holster it for use another day, fact is i don't know who if anyone's fault it is.

i am also not saying this is RMs fault in any way, i just used those for testing as it was mentioned there was a problem with them working as expected with vue 7, i will be continuing to buy and use RM's textures and characters as they kick ass', she is an awesome character and textur maker.

anyway i have probally wasted my time writing all the above as it probally won't work for anyone else but i thought i should share info, just incase it makes some sense to someone.
