NEW REFLECTIONS
The windows will alternate between pre-baked (cubemaps) and real-time (SSR) reflections depending on the angle you look.
a) "Cubemap Reflections" refer to pre-rendered, pseudo reflections.
- They are the primary source for reflective appearances, capturing reflections from static Cubemap texture files.
- They create a pseudo-3D effect, simulating a reflective appearance from your perspective.

b) "Screen Space Reflections (SSR)" are real-timed reflections.
- They work like a mirror and reflect the other side of the screen. All you see from reflections are real.
- SSR functions when viewing windows from narrow side angles, as it operates through screen mirroring.
*Activating ENB with Reflections can change the appearance of Screen Space Reflections (SSR). It may intensify them but could also cause flickering. It's worth giving a try!

POSSIBLE CONFLICTS
(Ultimate Window Overhaul will be referred to as UWOR.)
FlaconOil's Complete Retexture Project (SAFE TO OVERWRITE)
- There are 2 conflicting material (.BGSM) files (WindowSheetDeco01.BGSM, WrhsWindows2.BGSM). It would be best to let UWOR overwrite.
- There are 19 conflicting texture (.DDS) files. These completely depend on your preferences.
b) If you'd like FlaconOil's textures with more reflections, you can let UWOR's specular map textures ( ... _s.DDS) overwrite FlaconOil's. Which are:
- ResWindowSheet_s.DDS
- WindowSheetDeco01_s.DDS
- WrhsWindows02_s.DDS
- WindowsNeoclassic01_s.DDS
- PaintedWoodDoor_s.DDS
- DiamondDoors01_s.DDS
Enhanced Lights and FX (SAFE TO OVERWRITE)
ELFX's conflicting materials enable SSR and edit Specular Multiplier. UWOR's materials do the same plus with new cube maps. It is safe to let UWOR overwrite in conflicts.
Immersive Windows (UNPATCHABLE, LET IT OVERWRITE)
Immersive Windows mod uses glow maps to illuminate the windows.
Unfortunately, neither SSR nor Cubemap Reflections work together with Glowmaps. However, It is still possible to use the mods together. Let Immersive Windows load after UWOR. SSR and Cubemaps will be disabled; however, UWOR's textures and Immersive Windows' illumination will work together.
Better Fake Reflections (AFFECTS CUBEMAP REFLECTIONS)
This mod disables all Cubemap Reflections and replaces them with Cubemap Glow. (Changes EyeCubeMap.dds)
If you install Better Fake Reflections, UWOR's Cubemap Reflections will be disabled as well as all fake reflections.
You can combine it with the 'No Fake Reflections' cube map pack option in the UWOR's installer.
Fixed Flickering Puddles(AFFECTS CUBEMAP REFLECTIONS)
This mod affects Cubemap Reflections (Changes EyeCubeMap.dds)
If you use Fixed Flickering Puddles, UWOR's Cubemap Reflections might not work, and there is no fix.

RECOMMENDED MODS & MODS USED IN SCREENSHOTS
Some of them are used in the screenshots, some are my recommendations.
- Langley's HD Textures Workshop (by Langley)
- ***(You might want to use .BA2 packed version of Langley's HD Textures Workshop, but don't forget to endorse the original mod)
- FlaconOil's Complete Retexture Project (by FlaconOil).
- Wetness Shader Fix (by Ablaze666).
- If you want to get rid of flickering puddles without any conflict, I recommend: Luxor's Puddle Remover (by luxor8071) -or- No More Fake Puddles (by christoph392008)
- Do you think SSR looks nice with windows? Then you should check out Luxor's Vehicle SSR mod (by luxor8071) to see how good it looks with vehicles!
- I suggest using an ENB! SSR works appropriately with one. I'm currently using THE ENHANCER, which I found to be performance-friendly and natural-looking.
