I am currently working on the Scania 143 made by Ekualiser which I'm sure you're all ware of. It hasn't been updated in a long time, and I took the courage to update the window animations.
I took some time to analyse how they work and how to make them etc. I got a 'test' window animation to work, which I'm very chuffed about:

The animation is great and functions how I want it to. I was about to do the the one on the right and the interior ones, then realised there was an obstacle in front of me.
As you can see in the photo above, there is a 'fixed' window behind my animated window. I presume it's there because there were no animated windows when Ekualiser made the mod and so the fixed window is part of the overall truck model. Here is a better pic:

So, I decided that I was going to simply import the 143 truck model and just delete those 'fixed' windows; once I did this, I just popped the 'now edited' .pmd and .pmg back into the mod and I hoped that the fixed 'window' would be gone, as shown here:

As soon as I entered the game, I realised it was not as simple as this. The 'fixed windows' were gone. But I got this:

So I assume its not easy as just editing a mesh and then just replacing it? What have I done wrong here? And I would appreciate some steps to help, maybe a different way to get rid of the 'fixed' windows?
Thanks a bunch, and Merry Christmas!
