Realistic metal textures So guys i'm not the greatest when it comes to metallic textures, any other textures i can do. I can easily create a silver(Natural) metallic texture, But i cannot create a Green(Painted) Metallic texture. I am currently working on this Renault and I just cant seem to find the right way to create a good texture for it. What texture should I use to create the Metallic body of the Tank and how do i achieve this or apply it to the tank, do I create my own diffuse and glossy shader with a normal map or do I use a texture and give it a normal map and a glossy map. And how would I set this all up in the Nodes correctly with glossy shaders and Bump maps.
Thanks Guys.
Metal materials are pure gloss and if you want it painted then 

1-It's metal that have been painted (like it's been sprayed with paint)
which is gloss shader mixed with a paint material using a mix shader and the Factor is an image texture made to tell blender where is gloss and where is paint

2-It's like metal that is factory painted
which is gloss with an image texture

note that metal has a colored rim light 

for the best realistic result look up PBR materials 

I recommend blender guru's tutorial ..2 videos that explain PBR materials the second one is about accurate metal materials but you need to see the first one
