Hey guys, Welcome to a new blender tutorial.
So, in this tutorial we are going to make this painted metal shader in Eevee.
So, yeah lets start. We don’t need this default cube.
So, ill just select and delete it. So, tap your delete key.
Now, we need to add a sphere so, Shift+A under the mesh, the UV Sphere. This sphere is a
bit flat we need to smooth it out so, select the sphere and under the object select shade
smooth. Now the sphere is smooth but the edges are
a bit flat so, to smooth out the edges we need to add a modifier and we need the subdivision
modifier. So, just apply it. Now, the sphere is completely smooth.
Okay, now go into the Look Dev mode and Up here you can select the default HDR’s that
blender provides, so I’ll just select the default one , the forest one.
No we are done with the setup so we will start working on our shader so for that we will
need the shader editor. So, I’ll just split my screen an to here where
it says 3D view-port I”ll just select the Shader Editor.
Now what we need is two principled BSDF shaders, one will be for the metal and one will be
for the paint. So, duplicate the shader. So, now we have 2 principled shaders.
So, somehow we want to mix there two shaders so, for that I’ll add a Mix Shader.
I’ll pop that Mix Shader right here and I’ll connect the second principled shader into
the second input of the Mix Shader. No these both shaders are mixed. We need a
texture to control the amount of paint and metal so we need to plug something into this
factor. So, let me make the secone principled completely Black.
If I make the factor 0, the first principled is being applied and if I make the factor
1 the second is applied. So we will need a grey scale texture that
controls the amount of paint and metal. So for that I will use a noise texture. So, Shift+A
under the Texture, I’ll add a Noise Texture. Now I will also add a color ramp for more
fine control. The factor of the noise connects into the
factor of the color ramp and the color of the color ramp connects into the factor of
the mix shader. So, now this noise texture is a grey scale
texture. So, we need to change these settings. So first,
I’ll bump up the detail to 16 so that is the maximum that we can go, the scale, I’ll make
it 3. Now, I’ll just slide this black slider and
this white slider until you get something like this.
In the first principled shader, now this will be the metal so, I’ll just leave the color
to white. Now we need some roughness but I’ll bump up the specular and I’ll bump up the
metallic. So now as you can see, it looks like metal but the roughness is a bit too
much, so I’ll just drop down the roughness. Okay, so we have some shiny metal. Okay in
the second principled shader, I’ll turn down the roughness, so this paint is a bit glossy
also I’ll bump up the specular. And change the color to whatever you want. I will make
it a faint orange color. This looks good. But one more thing, this paint is a bit glossy
and the metal is also a bit glossy so we don’t have that surface detail so for that I’ll
quickly add a Bump. I’ll just add a noise texture and I’ll hit
Shift+A and I’ll just search here, search for Bump. So now we have our Bump Node.Now
this is very important, the factor of this new noise goes into the height of the bump
and the normal of this bump goes into the normal of the principled bsdf. I’ll bump up
the detail.I’ll just turn down the strength until we get something like this. So, we have
some bump going on. Okay, so something like this looks good. Now we will do same for the
paint. So, I’ll just select this, the noise and the
bump and I’ll hit Shift+D to duplicate them, I’ll just bring them here and again the normal
of this bump goes into the normal of the second bsdf.
Okay now, as you can see the paint also have some detail. Bump up the distortion to 1.
The detail is a bit too much for the paint so, something like that.
Okay Guys that’s it. So this was a quick tutorial on how
to make a painted metal shader in blender.
