Several advanced(probably) questions

[Romulator]

If I can offer some support, we do have a Discord server where a couple of other modders could help out as well if you're interested. You could ask for some assistance with scripting and we may be able to provide more support and perhaps in real-time too, depending on who is online.

A link, if you are interested: https://discordapp.com/invite/dKNcz4A

Also, you mentioned being a bit unsure as to what "Override Defaults" accomplishes -- that basically refers to whether or not the entity should prioritise settings you have made in the Level Editor as opposed to the settings specified in the User Defined Variables in the Model Editor.
