Quick qestion:

Have Spec map:

MAtlib settings:

Code: [Select]

"name" : "ID884",
"diffuse" : "185,185,185,255",
"Ax" : "0.077",
"Ay" : "7",
"m" : "0.5",
"tex_diffuse" : "WindowDouble.dds",
"tex_normal" : "",
"tex_env" : "WindowDouble_Spec.dds",
"tex_opacity" : "",
"tex_reflectance" : ""


If "m": 0.5
result

If "m: 0.05
result

because it is not specular map but roughness map, 0-means perfect mirror and 1 perfect matte material...
