The Cathedral Concept
Lightweight Grass & Landscape Overhaul

The Cathedral Concept is a comprehensive visual overhaul for Skyrim. It is lightweight, consisting mostly of retextures and improved models, so that you can use it as a foundation without having to worry extensively about compatibility. 

The grass found in this mod is far lighter and more efficient than the vanilla grass. I have thus been able to create dense grass that renders on 3x as many surfaces as vanilla as well as on steep mountain slopes, so regions like the Reach become blanketed in grass. Given the abundance of new textures this mod offers, memory usage will be increased. 

This grass also comes with landscape textures and terrain LOD that has had the grass baked in so your grass will blend seamlessly into the distance.

An INI file is included. If you think your computer can handle it, you can increase the grass density by decreasing iMinGrassSize.

Grass: We've got some pretty revolutionary stuff. No bullshit gimmicks like other performance grass mods. Just an understanding that simplicity is the best design.These models consist of only 3 triangles. For perspective, your typical shrub consists of 1500. Most grasses in vanilla or mods consist of 12 to 200 triangles. The thing about a blade of grass is that it's 2D, and adding a whole bunch of extra triangles isn't going to change or improve that, so then why do it? Because you hate people and you want to explode computers, that's the only explanation I can come up with. The other thing about grass mods that just perplexes me is that they'll put 3 little wispy 2 pixel wide threads of grass on a single texture. Essentially wasting 4,000,000 pixels of the 4,194,304 found in a 2k texture. Now you need to load hundreds of more models and hundreds of more textures, just to compensate for all that waste. The simple solution is to add more grass to your textures, to all of them, even the ones with flowers as they have plenty of space for some added grass
3D Ground CoverIn addition to grass, I've made low lying ground cover so you'll have 3D ground. For the pineforest, here's an example of 3D ground with small plants growing out the floor. Notice how cohesive the landscape texture and grass colors are.  Here's an example with piles of aspen leaves covering the ground. The models I used here again consist of only 3 triangles, and with just a few of these you get incredible coverage of all your loaded terrain. Similar approaches in alternate mods use 100's of triangles to accomplish a lower quality result. The models used in these mods are based on the clover models in the vanilla game and what you end up with is floating leaves at knee height that look fucking stupid. I fixed the clover piles btw. Keep an eye out for them in Riverwood and you'll know what I'm talking about. Who needs parallax when you can have actual 3D that you can walk through?
Flowers: I did cool stuff with - you get patches of hella flowers because flowers are sexy and if you're too macho to like flowers, well then consider that these will give your girlfriend a reason to enjoy the game so she'll cut you some slack for neglecting her for Skyrim. I made some of them 3D like these lupins and it uses as many resources as the traditional game would use to render a few 2D blades of glass. Pretty fuckin sweet.


This mod requires Cathedral Weathers & Seasons, designed specifically for this grass mod. Grass color is controlled by the texture and the weather. For this reason, in order to have grass that matches the landscape and have smooth transitions into LOD, Cathedral Weathers is required. 
You can still use other weather mods, but grass won't have the intended look.

Put the following in your SkyrimPrefs.ini. It does the same thing as Better Dynamic Snow. 


See ModPicker page.

Standard Blended Roads is included. To use Really Blended Roads, use the patch.

Not compatible with other landscape or terrain LOD mods for aesthetic purposes. 3D Landscapes seems compatible though.

Not compatible with Terrain LOD Redone : An equivalent is included.

Semi compatible with snow textures : LGO snow will be overwritten.

Compatible with A Quality World Map : Load QWM after LGO.
Compatible with Majestic Mountains : Load MM before LGO.
Compatible with trees mods and with DynDOLOD.

There are two primary philosophies when it comes to modding, Parlor and Cathedral, originally coined by the former modder, Wrye.

In the Parlor view, we consider mods as privately owned works of art displayed in a modder's parlor. We invite others to come appreciate our work. We directly receive compliments and endorsements, encouraging us to produce further work. 

In the Cathedral Concept, we consider modding a joint effort. We share our work with each other to foster further mod development, to keep the community alive, and to contribute in the construction of mods of monumental scale. Individually, our contributions may be small and not worth doing for themselves, but by each person contributing something, we construct something larger and more worthwhile than any of us could do on our own.
