Hi Steelharvest sorry i didnt get back to you the orange Umark in gods eye mode did you make a copy of your SH3 install so you have a stock SH3 install as well as a GWX SH3 install if so go into your GWX install open data folder then open up Misc folder scroll down to the bottom of the page delete UMark.tga file
then copy and paste the UMark.tga file from your SH3 Stock Unmoded install and there you go you have the orange UMark in your GWX SH3 install
if you dont have a stock install of SH3 PM me your email address and i will reply and send you the UMark.tga file from my stock SH3 install
