About this mod

A module of the OBGE v3 project aimed at replacing Oblivion\'s default water.

Permissions and credits
This mod is a module of the OBGE Project, and REQUIRES the OBGE v3 Core to already be installed. If you are unaware of what that is, look at either the current OBGE Forum Thread on the official Bethesda Forums, Navigate to the OBGEv3 TESNexus Page, or explore the OBGE Wiki found here:


WARNING: Because of the dependencies of OBGE on the specifics of graphics drivers, there is a possibility you will encounter odd graphical errors. I can no longer provide support for such issues. If you are extremely intent on getting this to work and encounter such graphical oddities my only suggestion is to try the OBGE 3.1 release candidate, which is even more likely to have graphical errors. I also no longer have a link to it, so you will have to search for it.

The only known major graphical oddity I can provide a fix for is circles of light randomly appearing and disappearing on walls:

Put the file in your shaders/override directory. Make sure you have bCompileSources set to 1 in your OBGE ini.


The story of this project begins with the precursor to the OBGEv2 project, the long-gone OVEP project. One of OVEP's main goals was to eventually replace Oblivion's water shader. Even with mods and INI tweaks, Oblivion's water is blocky, unnatural, and unaesthetic. Unfortunately, OVEP ended up dying and the water didn't get replaced. A long while later, a series of rapid advancements in what the OBGE team realized they could do with just full-screen shaders finally led to this replacement for Oblivion's water shader, albeit with a few bugs.

About two months were initially spent on the creation of the water shader itself, with another two months spent on reintegrating the Liquid Water fork into the main OBGE project and on working out the kinks in OBGE Liquid Water v1.X.X. The results of such a long development time for a shader do show however, with the final water replacement featuring the following:

Reflections and Refractions
Realistic Speculars
Water Surface Refraction
High Quality Normal Maps
Physically Based Light Scattering System
Underwater Volume Fogging
Smooth Shoreline Transitions
Water Caustics
Accounts For Weather
Looks Natural In All Conditions
Works In Exteriors And Interiors
Fully Customizable
Supports Cell-Based Unique Settings
