Till now I only changed UI element names and envVars, but I kept the 
flags that are send to the plug-in untouched, so this shouldn't be the 
issue.

O.K., I will change the flags in the plugin to the suggested ones

Will look into this, should be fixed today.

Some more stuff from my side, I will start editing the cmake files as 
well, but need some assitance in the begining.
The maya2osg_utility.mel needs to be installed properly. I found 2 files 
to edit and 2 deprecated VS files:
configure_installer.cmake
maya2osg-maininstaller.iss
maya2osg.vcxproject
maya2osg.vcxproject.filters

I will edit all 4 files ( with allmighty copy and paste tool :-) ), 
please to confirm.

For my understanding, about the new textfields, and to be able to test 
functionality:
Vertex / Fragment Declare are injected into GLSL code after the existing 
declaration block and before any procedure definition.
Vertex / Fragment Compute are injected at the end of the GLSL code, so 
in the main procedure befor the closing braces.
Is this right ?

In an earlier mail you mentioned that the injection happens if ALL the 
textfields do specify a file, is this correct ?
Is there in no case, where one wants to just overwrite the Fragment 
color, without the need for any other ( Declare / Compute ) requirement ?

Cheers, PP
