After putting my characters on source, most of everything is fine, the rigging, the mesh, and the most of of texture. How ever upon closer examination, the whole model is VERY, VERY TINY. and it lays on the floor, like I want it to stand up and sized to be normal like a source tf2 model. Is there like an option to scale it so source units or see those units?

Also another issue, i have glasses on the model that are flat but they don't show up. On blender, its like only one layer instead of being 3d, does the source engine not like this kind of thing happening.

Then for some reason on another model, same issues but the eyes which are white end up looking black on source but fine with blender, i used normal texture painting and painted them white.

Everything on each model is one object and one texture too.
