Photon Shaders

This is a small update fixing a few issues that were found in v1.2.

Hi everyone, Despite my extremely sporadic work schedule for this project, it's time for another update! I am very excited about this one - while the previous update mostly focused on technical changes, this one brings a lot more atmosphere to the game. ## Weather and Clouds - The previous daily weather system has been replaced with a much more dynamic system, which some people will remember from extremely old Photon versions. This provides much more natural weather variation which is also influenced by the biome you're in. - The weather affects the clouds, fog and even the waving plants. - The downside of this is that you can no longer adjust the weather per-day. - Cumulus congestus clouds may now appear alongside the regular cumulus clouds rather than replacing them. - I've adjusted a lot of the cloud shapes and lighting. Altostratus-like clouds will also appear now. - Reworked rainy weather. - Lightning flashes now illuminate the sky. - Added rainbows :) ## Crepuscular Rays - Added crepuscular rays through the clouds. - These are also controlled by the new weather system. ## Colored Lights Fog Scattering - When _Colored Lights_ is enabled, the fog will be illuminated by light sources. - I also made the voxel volume for the Colored Lights centered ahead of the player rather than on them, so you can see colored lights much further with no performance impact. ## Improved Indirect Lighting - SH Skylight is improved by using bent normals and enabled by default. - Added a new approximation for indirect subsurface scattering based on AO. - This makes shaded areas and dusk/dawn look much more natural. ## Miscellaneous - New fast fog approximation, which is used in reflections, behind translucents and when volumetric fog is disabled. This means that fog no longer disappears in these cases. - Updated water waves - I think they look much nicer now and the pattern is much less repetitive. - Updated the moon with a new textured look. - Improved the Pale Garden

- added Chinese translation by NakiriRuri and OrzMiku - added some modded blocks to block.properties - adjust TAA to reduce ghosting - adjust fog - enable water texture on underground water for improved visibility - hardcoded materials for 1.21 and 1.21.4 additions - improve cloud filtering - improve rough reflections - improve silver lining on clouds - increase sky vibrance, especially at sunset - multilayer reflections: water no longer loses its surface behind stained glass - new cloud types: cirrocumulus clouds, noctilucent clouds - new sky option: Galaxy (milky way in the night sky) - small plants are displaced close to the player - water wave height variation - many bug fixes and optimisations
