Rafael's Shader Pack

Shaders of light! Pixels of magic!

A shader pack for OpenMW, using different shaders I've written or collected, tweaked, enhanced, fixed, optimized and changed in different ways, now in a single convenient place.

Enjoy a quality ambient occlusion to make the world look more grounded, quality anti-aliasing, enhanced lighting and weather effects to bring out the best out of Morrowind, while not changing the vanilla experience, and with a very small performance hit.

How to install:

0. Make sure you have OpenMW 0. 49 or 0. 50

1. Add RafaelsShaderPack to Data Directories in the launcher

2. Set OpenMW gamma to 1. 0 and Minimum Interior Brightness to 0. 00 (no need for such hacks since we're using tonemapping!), and ensure shaders are activated (if you use a higher view distance than 10 cells, I'd recommend going to 10, max. Reasoning is that shaders are tweaked for 2-10 cells, and lower view distances will also minimize any LOD or pop-in issues you'd encounter)

3. In-game, press F2 (you might need to enable postprocess from the in-game menu, in which case OpenMW tells you to do that), and move the following shaders from Inactive to Active in this order: HBAO, VAIO, godrays, DIVE, wetworld, tonemap, SMAA (or you can just copy and paste "chain = HBAO,VAIO,godrays,DIVE,wetworld,tonemap,SMAA" in the section of your settings.cfg)

4. If you want temporal filtering (TAA minus temporal supersampling) or motion blur, then add SMB at the end. If not, skip it.

Optional steps for extras:

1. If you want volumetric clouds or physically-based sky rendering, check the clouds and sky options in VAIO, but be warned that due to the way transparent objects and post process shaders are handled in OMW, this can lead to blending issues. Using the "Transparent Postpass" option in the launcher is recommended if using any of these settings. Even so, this will not solve all blending problems, so these options are disabled by default and up to each individual user to enable or disable as they see fit

2. If you want filtered shadows with penumbra, PBR lighting, or enhanced water (all heavily recommended) check the Optional Files, each has their own specific instructions included, as they are core shaders and not post process effects/shaders

3. If you want ground snow when it's snowing, then the wetworld shader now has an option for that. It's not as good as it could be, as the shader

cannot determine if pixels belong to static objects, or moving characters, or your hands in first person view, which would enable some really nice stuff. As such, it is disabled by default

Steps for performance boost:

Set the in-game water "reflection shader detail" to sky, and let the wetworld water SSR do the reflections instead. Considering this is anywhere between a 10% and 30% boost, it is beyond recommended.
