It would be great if these keywords from standard and post processing were loaded for everyone so maps and shaders don't break anymore.
Unity Standard keywords and Post Processing V2.
Additionally if you're super nice you could make default keywords for shader devs to use so they wouldn't break the game anymore and had some sort of best practice to follow.
ONE, TWO, THREE ,FOUR ,FIVE ,SIX ,SEVEN ,EIGHT ,NINE ,TEN ,ELEVEN ,TWELVE ,THIRTEEN ,FOURTEEN ,FIFTEEN ,SIXTEEN ,SEVENTEEN ,EIGHTEEN ,NINETEEN ,TWENTY
This would give shader devs 20 keywords to mess with so no one would have to worry about their keywords breaking anymore if they follow best practices.
It would take 20 seconds to copy and paste these into the loading screen material and fix all the basic keyword problems with the game.
