Quick correction of my last comment. If making a Mt5 file that should work like the MCL file using the Add to Scene feature the line in the txt

shaderTree

{

node "poser" "PoserSurface"

{

name "PoserSurface"

simply needs to be changed to 

shaderTree

{

node NO_MAP

{

name "PoserSurface"

this will make sure not to affect the Base Poser Layer and you get the option to load the new layer to any selected bodypart. removing eventual other issues change the first lines

actor $CURRENT

{

material 3_SkinForearm

to

actor $CURRENT

{

material

now this starts to solve allot of issues and the layer can be added to the bodypart of your choice, now a solution to remove the layers. Starting to get good results here :)
