Smoothness and Metalness in Unity

[Jérémie]

Hello! 

I am currently trying to make my own mod for KSP, allready done the modeling, texturing and all the stuff.
I imported the blender file into Unity and succeed to have the main texture and the normal map imported.

But I do not succeed to import a roughness/smoothness map and a metallic map.
I read that I have to make a RGBA file with the metalic in R, normal in G and smooth in A. If it is that, how can I do so?

Thanks in advance!

If you look through the shaders in Unity you'll notice they all have different texture inputs. Create a material and set the shader to KSP/Bumped - notice the "_MainTex (RGB spec(A)) beside the top texture slot - this is looking for a RGB with spec in alpha and a second texture (_BumpMap). Now switch the shader to KSP/Diffuse and you'll see it's looking for only one texture in a RGB format denoted by "_MainTex (RGB)". Benjee has a real nice metallic on a docking port in Benjee10_SharedAssets - I'll add a link here if I can find it again.
