OK, so, there was a major issue with the VaPER - Bubble Stream TallWide nif in that the bubbles would stop at an angle that was not quite horizontal. Not good, but surprisingly hard to spot.
Also following feedback from a very polite modder, I've made adjustments to how long the bubbles will stay at the surface. If people want bubbles that last for longer (say for swamps or thicker liquids with a lower surface tension) then either adjust the particle lifespans or ask me for additional versions.
Also, following feedback from Arthmoor on the weather boxes, I've realised that modders often expect a fairly close fit between the marker editor and the particle effect, so I've tried to match that more precisely (not an easy task in NifSkope) for the point of particle emission and the plane where the particles get stuck. You should still check the effect in-game to ensure it works out ok: the water surface is a very precise point on the z-axis after all.
I also had a request to add shorter versions that weren't simply scaled down (which reduces bubble size and speed proportionately).
So, here's http://www.tesnexus.com/downloads/file.php?id=35526 v2.
v2.0 Added two medium height nifs, which allows placement in tighter spaces without shrinking the bubbles. Fixed the wide dispersal collider to be more precisely horizontal. Shortened bubble lifespans slightly to better reflect water behaviour. Compressed the texture.
If you're already using the v1 "VaPER - Bubble Stream TallNarrow.nif" then you probably don't *need* to update as that worked pretty well. I'd recommend updating to the latest version of the resources anyway though. I don't think it's great to be continually updating resource files. Expanding and adding to, sure, but I hope I don't have to do too many "fixes". Sorry about this: I guess I'm out of practice still.
I look forward to seeing the final results of your work in other mods...sometimes it's the little things that make all the difference in a game...
I heartily concur. A good dungeon crawl isn't simply about the shiny armour or weapon at the end. A good house isn't just about having lots of containers. A good landscape isn't just about, uhh, having lots of trees...?
