I'm back..again.
I went to use the A3 toolbox for blender to export my model to O2 with the P3D option. However, my model, which starts off as this, comes out as something totally different once it is exported into Arma 3. The O2 model is the same: here.
Further, my textures are not loading in A3, but one issue at a time.
EDIT: It appears that O2 is cutting off the top half of the model, loading it, and then drastically increasing the size. I have no idea how to fix that problem.
