Thanks, but this doesn't explain much. This only shows editing existing object, not creating a new one. Can you record a tutorial?

It's all about money, nobody knows nothing and this few guys that know something won't tell a word because they want to get money from their knowledge... I understand that.

So this is what I did:
Resizing the object > edit mode > triangulate faces > subdivide > uv unwrap > cube projection > adding the texture, uv, uvmap, gl5l (something like that), renaming the texture (everyting in the Kalcor's videos) > export dff

This is how my object looks in Blender

And this is what I get in-game??
