Differences between ESMs and ESPs

[algaeb]

Hi,

 

I'm trying to find a good technical description of what the difference is, so I can understand when and why it's helpful to do a Master Update.

 

I'd appreciate if someone could tell me how much of this page applies to FO3:

For example, is the following true for FO3 or just for the Elder Scrolls?

 

Esm/Esm Land Bug

When one esm modifies in any way a worldspace cell of another esm, the land bug occurs in gameplay. The land bug is where the local land textures (and often static buildings, etc.) disappear in gameplay. This happens not just in a few isolated spots, but typically everywhere.

 

Thanks.
