So it is the Blender after all, guess no other choice, Thanks for the info

@TheWatcher Editing animation and model needs Blender and there are tutorials online to teach you how to do it.
@泽0v0 Sorry but the mod is out of maintaince because I lost my developing files accidentally.

your urg 1 local server reload bug what time can fix

Sorry to bother but I've always aspire to be a modder like you and KJ and hopefuly I could become better, btw how are you able to change the animation and add a few attachment to the weapon? For now I only understand on porting mod and change the animation or attachment from the decompiled file and qc files using crowbar. What kind of method you used on modding?
