Triangulation messes up my set texture positions

Hi, I’m fairly new to Sketchup but have been using the program for a while. I got a model to where I like and want to test it in my game engine of choice, however the engine does require I use a plugin to triangulate the model in order for it to render properly. I’ve been using an old plugin for this for quite some time, however now that I have a model where I adjusted the texture positioning to be where I want it in Sketchup (right click -> Texture -> Position, etc.), triangulating the model resets this or at least just messes it up. Is there a plugin or a way out there where I can fix this? Of course I’ve undone the triangulation and also have kept the correct project file intact, I just mean along the lines of where I can export it properly, no help needed getting it back to how it was. Thanks!

What do you use to triangulate?

(Btw, you can upload images directly to the forum.)

BTW#2 you can also upload sample skp files to the forum!

Is it UV mapped? Plugins are available to do such.
