Hi All - I haven´t yet understood a principle of material properties and am looking forward to any help and explanation
First I show an example picture of what I try to achieve: The shown street is wet (so already shiny), but the puddles on the street should become shining or mirroring much much more.
Scenario 1 (below) is a common simple textured Albedo material. It is a wooden floor for example, which should already have a little amount of reflection for itself.
Scenario 2 (below) is the same albedo material, but supplemented by a roughness-map. The goal is to have spots on the floor, which should shine or reflect much more (like puddles on a street which itself is a little wet already ). This works very well and as expected but: The Albedo floor now can't retain its own little shinyness and the material window doesn't allow to keep this Albedo setting. Surprisingly there is only a Metallic controller left now, which is confusing for me as I don't intend anything with metallic but only with shinyness.
Probably I am just missing something only and as I said, I am happy about any clarification or help about what or how is to go on here - Thanks in advance
