Sorry for asking about this here
@lymond but the BUG subforum isn't active these days and you seem to know everything about this. I installed BUG 4.4 (latest one) from sourceforge in the CustomAssets folder. Anyways I am able to open forum games and play games normally with BUG enabled but a few other mods like StartingPoints don't work. I didn't back up the vanilla dll but you said that's only for BULL. Does the BUG I downloaded include BULL or not? And is there any easy way to get these mods to work? If I uninstall BUG and reinstall as aa separate mod will they work?
BULL is a separate install. It's a zip file that you unzip and copy files into custom assets (instructions are in there but it's quite easy), and place the DLL file to the Assets folder, after renaming the vanilla dll (just add an extra extension so it is not read).
Sorry, I don't know StartingPoints. Most standalone mods (mods you have to load), are usually set to ignore Custom Assets so there should be no conflict. The BULL dll file likely would cause a conflict, but you can simply change back to the vanilla dll before loading another mod.
However, let me make one thing clear about the Custom Assets folder. It is simply what the name suggests, a place for custom assets (another way of saying modded files). The vanilla game reads custom assets folder first to find any replacement files for vanilla assets should they exist, then otherwise uses the vanilla assets. The Custom Assets folder is disposable. That is, you can delete the folder entirely with no harm as the game will simply regenerate a new CA folder. You can also just simply rename the CA folder so that the current configuration you have in it (such as BUG) is ignored. The game will create a fresh empty CA folder.
I keep a copy of CA folder with BUG/BULL/Blue Marble and a copy of CA with just Blue Marble that I switch between simply by renaming the folders (bug and van). I use the van version if I'm running any other modpacks.
When you say BUG as separate mod, I assume you mean a standalone install. It would be exactly that - standalone. You will have to load BUG as a mod to work and it would ignore custom assets. A standalone mod would really only work with another mod or mod component if they were incorporate into the installation....as far as I know. (I'm not a modder myself but just go with the experience I've had installing these things over the years)
StartingPoints I suspect is a mod component. Likely it could be incorporated in some way - either in CA with BUG or a BUG standalone install, but I'm not sure how to do that myself. Mods and mod components are certainly incorporated in other mods all the time - BUG is in a lot of different modpacks out there.
On another note, you can have both the standalone install of BUG/BULL and the CA install of BUG/BULL - I do. Only really have the standalone install in case someone else here does - it happens sometimes though rarely. But the CA install is most useful playing games on this forum here since saves are easily accessible to everyone. Again, not sure what StartingPoints mod is but there may be a way of incorporating it into the CA BUG install and I would suspect not create save conflicts.
Standalone mods of any type though are standalone - you can only have one running at a time.
