I think the guy is confusing blur with bloom. I explicitly wrote in my realSKY Readme file that bloom postprocessing is used by the game when Effects settings are set to Unlimited. This is unrelated to the mod, although realSKY provides better postprocessing given engine limitations. I wonder why I waste time writing Readme files.
About effects, the best currently available are from Stary's Unified Effects package. For the ODS mod, me and guuruu have been improving those and fixing any mistakes, typos, wrongly referenced shaders, etc. Maybe some day I'll think about re-releasing them as a standalone package.
Much better looking effects are simply not possible, the graphics engine is not capable of features like proper heat waves, volumetric clouds, etc. The game is old, live with it. Besides, to be asking for even better freeware mods than the ones already available is a bit insulting and annoying. I almost lost my sanity while working with obsessive care and precision on some add-ons (which are free). There are people spending their free time to make others happier, with absolutely nothing in return. So let's be grateful for what the community already offers. Rant over.
