Weird interior issue.

[Zerosleepless]

So basically some of my vanilla interiors that are altered by mods aren't loading properly.

The rooms are "invisible" they don't show up until i step in them, and once i step outside , they disappear again.

Other bugs occur in these interiors as well such as npcs being all black/textureless , lighting issues(flickering lights , walls going from being fully lit to dark when i'm moving my camera around....)

I know witch mod is to blame , it's ETAC (expanded towns and cities) , the thing is , i thoroughly checked the compatibility page  and all the mods that i suspected to conflict with it are listed as compatible...

The mods i suspected are: RLO(realistic lighting overhaul) , URWL (ultra realistic world lighting) and jk's skyrim( towns only)

 

Here are some pics to better illustrate the issue:

 

 

 

When i'm outside , the room is invisible.

 

 

 

As soon as i step in, the room pops into existence , when i step out , it disappears again. 

 

 

 

 

The affected interiors as far as i can tell are all the inns as well as some vanilla shops 

I have had the same issue with skyrim radioactive witch alters some vanilla shops and inns , uninstalling it fixed the issue but i really don't want to uninstall ETAC.

Sounds like trouble with room bounds. Mod authors must not have set them up properly to have portals lined up with the doorways. The room bounds hid anything inside them and only render what the player can see through the portals until the player steps inside the room. This saves a lot on resources and helps with fps but it is hard to setup room bounds properly. The easier thing to do is use occlusion planes. You can run one of your mods through the ck and check to see if it has a room bound or not but sounds like it does. You can also fix the room bound issue yourself there are a lot of tutorials for room bounds on youtube. I think there was one by darkfox or something like that.

That does seem to be the issue from what i can tell , I've never touched the CK before and will need a bit of time to learn how to use it to fix it though .

Since the affected areas are so few , i think it's feasible to fix them manually.

Anyways thank you so much for the answer.
