Wow, this is awesome, it makes ent-modding way easier now. Would have been useful for my project I was working on last year. I got burned out on it, but I might have to come back to it now!
I hope you continue to work on this, being able to see entities selected, and move them around in the viewport like GtkRadiant, would make things super smooth.
Beautiful! I'm very glad to have some proper HD textures for JK2!
It goes without saying, but this works very good in JK3 too, with "Jedi Outcast - Academy" and "Movie Duels".
