    Hi guys,
    working on a 2019.3 UPR template, using UPR Lit Shader with Specular Mode.

    Is a problem I read before in some threads, but this time I cannot resolve it (when the material looks correct only when you open the inspector and "refresh" it)

    Due to I change the material maps (also smoothness values and so) via script at runtime, I use the keywords as follow:

    "_SPECGLOSSMAP"
    "_SMOOTHNESS"
    "_NORMALMAP"

    and load the maps slots as follow:
    "_BaseColor"
    "_SpecGlossMap"
    "_BumpMap"

    As far as I know, this is correct, but Im missing something because in Debug Mode on Inspector I observe that when I load a Specular map, it loads correctly into the slot,
    BUT, it doesnt work properly until I look the inspector in Normal Mode, and also, when I change again to Debug Mode after the "refresh", the shader as added a "_METALLICSPECGLOSSMAP" keyword by itself, and removed the "_SPECGLOSSMAP".

    That is what i dont understand, because I setup the shader as Specular Mode from the beginning,

    Am I missing some aditional Keyword to make Lit Specular works properly?

    Many Thanks!!

    please help, anyone as this issue with Lit Shader in Specular Setup?
    I update the UPR to 7.2.0 but still the same.

    One curious thing is if I change the shader code from #pragma _METALLICSPECGLOSSMAP to #define, the Specular Map is loaded, but as no effect on editor (on the mesh), also it doesnt change the keyword by itself and dont make the "Inspector refresh effect"...

    Is like I need some more keyword to get Lit Shader understand the Specular Map... I tried keywords like "_GLOSSINES", "_SMOOTHNESS", "_GLOSSMAPSCALE"...but no luck

    Thanks guys!

    You can find the Keywords under Edit Shader:

    thanks mendemarcus!
    At the end, even if I use the specular setup, I also have to give the keyword "_METALLICSPECGLOSSMAP", to see the correct result.
    That was what I did not understand, if I use the Shader in Specular Mode,(an Specular Map), it didn't make sense to use a keyword for "Metal"....but it's the only way it works

    Thank you guys!
