I'm super new to RPG Maker and I'm having trouble with getting Galv's Message Busts script to work correctly. Every time the game tries to pull up a portrait, it'll say that it can't find the image. For example, the character whose portraits I was trying to test were called fira_portrait01, fira_portrait02, etc. When the error message is displayed for her, it would say it can't find it while citing the path Graphics/Pictures/fira_portrait01-1, so I changed the name to fira_portrait01-1, since the image is already in the Pictures and Faces folders. Then it gives me the same error message saying it can't find fira_portrait01-1-1. It does this with the Actor portraits as well, with my case saying it can't find Actor6-1. I may just be misunderstanding how this particular script works, but I read the guide in the script and looked at the demo provided.
Additionally, is there any way to prevent Galv's script from conflicting with other scripts? I'm using a script to change the font in the event menu and Zeus81's Map Effects, and they both cause the game to crash when I interact with NPCs with portraits, saying something about line 151 = nil NoMethodError. Are there alternatives to this script? I want to use busts in my game instead of regular portraits. Is using plugins/scripts easier in MV?
