Can somebody write the ultimate guide to shader keywords? There are many cluttered infos out there but I can't get them together. Does the same keyword in two shaders count twice? I have the hdrp default shaders, vegetation studio speedtree shaders (don't use them, though) and one shader graph and I get the message that I have more than 256 keywords in use. If I open up shader control from the asset store, it tells me that LayeredLitTessellation uses 101 Keywords and LayeredLit 99, Lit 97 and LitTessellation 73, which are almost all duplicated.
