Recently I met a problem that if I don't write
#pragma multi_compile_fwdbase then the shadows will never be shown. However, if I don't want shadows, it's ok without this command.
Actually there are two questions I want to know.
Shall I always write this command if my pass's tag is set to
"LightMode" = "ForwardBase"?
Recently I checked my custom shaders, a lot of shaders have no this command but all of them are working well, will it be a problem in the future?
