I want to add some new critters in my game. For example the Securitron from FN:V is there a way to turn it into a .frm ? Or how can I modify the existing ones like color their clothes change aspect? I've seen on Russian forum a very long time ago someone made the Mirelurk from F3 work in FOnline by making him a .frm.
There is no need to use frm, FOnline has a better format - fofrm.
It's a text file. See specification:
http://fonline.ru/forum/showthread.php?t=3836As usually with FOnline, it's in Russian. You can open some 2238 fofrm in text editor to see how it's done.
Render 3D model animation to separate frames with correct angle, save each frame as cropped PNG then link them in .fofrm. You can't forget about setting proper offsets in fofrm. In practice it's tiresome task and you must into 3D basics first. Maybe there is some tool that helps with it but I don't know.
