First of all, the majority of the work comes from planning ahead. From your screenshot, it looks like your model shouldn't take more than 700 tris at max. It's a basic fedora shape hat which can be done easily starting from a cylinder primitive.

Basically, you'll want to start removing edgeloops (I discussed that in the video). You can select an edge of vertices (alt+right click) and remove the loop (delete > edgeloop) to start winding down on polys. For more complicated meshes, you can also remove hidden geometry (stuff that can't be seen because it's hidden by other faces).

As for your question, it's really hard for me to understand what you are asking... It seems like you are having a problem baking your model. Sometimes you can get weird black artifacts for several reasons:

1) Overlapping geometry (make sure there are no duplicate vertices) Select all the vertices in your model > press "w" > remove doubles

2) Flipped normals. Make sure your normals are facing the correct way > select all your vertices and click "recalculate" under the normals tab in the left panel.


I really suggest starting over. It's better to do it a second time once you understand the process. Start with a plan: what do you want to make? A fedora. How can I make it? Starting with a cylinder and slowly extruding. What is my polygon limit? 1400. How can I stay within that limit while ensuring that my hat keeps its quality? Focus on the silhouette and utilize smoothing groups (remember that smoothing in video games isn't done by adding more tris!).

Ok thanks I will report my progress later...

Another problem How I can make an item for all class?

Check out this thread: http://psteamcommunity.yuanyoumao.com/groups/BlenderTutorialCommunity/discussions/4/864978109436584091/

ok thanks Could you give a guide about to test an item in game?

Once you compile your model, you'll be able to see it in the preview. If you want to test it in-game, use the itemtest map: http://wiki.teamfortress.com/wiki/Itemtest

How I can fix wrong position this hat (like screenshot below) for medic but I never get problem with engineer and heavy?

It's definitely an issue with your rig. Are you sure you are applying the hat model to the medic's bip_head bone? Decompile the medic model and use HIS bones-- not the bones of another class.

yeah I am applying my hat model with medic's bip_head bone like your video tutorial such as remove bip_head on object data option and not the bones of another class...

Try starting from a fresh scene. You might be getting weird results because you imported the medic after importing other classes (blender will merge bones by default). Fresh scene > import the medic model > import your hat > assign the bip_head bone to your hat > export > compile.

thanks for your answer but when I trying to test it in-game after always got crashed to desktop. How I can fix it?

Hm... I'm not sure what could be going wrong. Is it giving you any errors? Try verifying the integrity of the game cache.[dl.dropboxusercontent.com]

not working too, I've got crashed to desktop when I try to load this item on item test map

I've never had that issue before! :(

I'm not sure what is happening. Maybe you could try using the source SDK to test your model? It obviously won't be in-game, but at least if it works in the SDK you know something is wrong with the itemtest map... If you need help setting up the SDK to view your model, use this guide on fixing the SDK: http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=157717488
