Very basic minimally invasive PBR shaders for OpenMW 0.49 dev builds. Based on revision e4c70b7861. Don't install unless you know what you're doing. Make a backup of the vanilla shaders folder by COPYING it (NOT by renaming it), then copy these shaders over the base ones.
Implements basic lambert diffuse lighting and schlick-ggx specular lighting. Lighting math is done in (approximately) linear light. Configuration is in lighting_pbr.glsl.
These shaders attempt to automatically generate roughness data if there's no PBR specularity material available. To disable this, set PBR_AUTO_ROUGHNESS_MIN and PBR_AUTO_ROUGHNESS_MAX to the same value (0.75 for example).
Supports PBR specular materials. Red: metal, green: roughness, blue: ambient occlusion. If you want to use PBR materials where green is smoothness instead of roughness, change PBR_MAT_ROUGHNESS_INVERTED 0 to PBR_MAT_ROUGHNESS_INVERTED 1.
Make sure you have these settings set in settings.cfg to avoid any possible issues:
force shaders = true
clamp lighting = false
force per pixel lighting = true
light bounds multiplier = 5
lighting method = shaders
