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.

Ok for the most part it works. Thank you so much!!!!
ill be sure to post this on the workshop when i get a change when i finish the other characters im working on. Ill give acknowledgments to you.
You saved my modeling hobby!!

There was a problem, I have glasses on the model but it only appears if i look at it from behind. I remember on blender I put everything together as one mesh.

Oh and another thing, just in case i might need the other stuff you mention. can you post how to make the shiny or transparent textures and other things like that because i might need to make a custom window or something transparent eventually down the road like for a map.

Oh and another thing, when I checked out the model in source filmmaker, it looked very small. How much blender units in scale should it be to look like a normal character in source?

Also in Addition, not really a big problem but point me in the right direction, only the spine bones appear has bones while everything else is in the unknown section as dots.

DONE!! Everything worked perfectly. It appears in model viewer. Sorry such a noob at this but I finally got it. Now whats next?

Another Character model i tried doing ended up like this. It had no armature at all.

Well i tried and nothing came out to the folder that model viewer would recognize. Then there was a big single error that stoped the entire thing.

So I made a character model on Blender alright. I worked hard on making a mesh, I have a very simple armature, only based purely on a skeleton (no other extra stuff yet like face riging and no animation), and I made my very own texture from texture painting which appears as an image on my computer.

What I want to know is by using the source tools provided as the addon, how do I make my creation appear on source filmmaker in the most simplest way you can put it. I know it is a very complicated procedure but please try to simplify it but still explain how to do it, if there is a process i need to do, not only say i have to do it but how exactly do I do it.

My knowledge and understanding of blender and source is pretty LIMITED and I have no idea what I am doing past of the point of finishing a model in the way I described.

I dont know my blender version and dont know how to check but Im pretty sure its the most modern one because I downloaded from the website less then a month ago.
My source addon from what blender is telling me when I click "check for updates" is the latest, 2.5.3 and its installed.

In the clearest and simplest way possible, explain the process of putting my CHARACTER creation (my mesh, my basic skeletal rig, and my texture) to Source Filmmaker in one nice character model like a SCOUT.
