================
=1.Installation=
================

Backup "Underwater Effects.fx" found in Data files\shaders\XEshaders.

Choose a colour scheme, Green-Blue, Blue, or Green. Extract the contents of the corresponding named directory to Data Files, or use a mod manager like Wrye Mash or MO2.

For uninstallation restore your backup.

================
=2.Requirements=
================

Dynamic ripples option (found in In MGE XE Distant Land tab) must be activated to make this work. To have the peak fix work properly I suggest a value of 40.

Requires MGE XE 0.13.0 or later:

===============
=3.Description=
===============

This is a reworked version of the MGE XE standard water shader. A lot of code from a lot of different water shaders was included, tweaked,
stitched together and forced to team play. So a major part of credit goes to the modders who originally came up with the appropriate code.
See credits section.

Optional features:

You can edit features at the top of the shader, located in Data Files/shaders/core-mods/XE Mod Water.fx

- Sewer waves, for ripples around Vivec and Molag Mar sewers. It is very heavy and both increases load times by 30 seconds and affects frame rate in exteriors. Not recommended except for screenshots.
- Distant waves.
- Foam whitecaps.
- Colour settings in the tweakables block.
 
============
=4.Features=
============

Different water color with a more reflective surface, different wave behavior and depth gradient. Greater depths will have a darker color. Also
sky color and color of sunlight contribute to water color. Overall color is a light blue.

Improved caustics by vtastek.

Peak fix by vtastek. The original MGE XE water shader would have let you peak under the water surface. This is exploit is no more possible.

Heavily tweaked foam. Foam will be generated on water shores as well as on wave tips. Foam is generated in every weather and also very subtly visible
during nights.

Ripples produced by the player will no longer trigger foam. Every other water shader with foam had this behavior and it bothered me big time.

Comes with a underwater effects shader for corresponding colors underwater.

fps impact is not different from standard MGE XE water shader, except sewer waves option.

- optional waves in far normals
- swell waves with optional foam, quite subtle by default
- lots of fixes and reworked code

1.3 to 1.3b

- reworked water colors
- made normals stronger
- lots of little tweaks here and there

===========

vtastek for general help, peak fix, improved caustics, optimized sewer waves and bits and pieces of code here and there.

phal and harnlarnm for original foam code and sewer waves.

abot for sewer waves port.

You can do with this shader what you want as long as you give proper credit to the original authors and me.
