Easy Procedural Rusty Metal - Blender Tutorial

Hey guys! Welcome back to the channel. Some of  you guys have asked me in the comments how I created this material that I use in one of my  videos. So I decided to create this tutorial to show you step by step how to make it and  you'll see that it's actually quite easy. So this is the final result. It's really cool and  all procedural, so you can easily customize it. By the way if you have any suggestions for another  blender tutorial just let me know in the comments of this video. Without any

further ado, let's  get started! Here we have a sphere to preview the material. I'm going to use the node Wrangler  add-on in this tutorial, so if you don't have it enabled, you can just go to Edit, Preferences  Add-ons, search for Node and enable Node Wrangler. With the sphere selected, I'm gonna go to the  Shader Editor, add a new material and rename it to Rusty Metal. Now I'm going to press  Shift+A and search for the Musgrave Texture. I'm going to hold Ctrl+Shift and  select the node to prev

iew the result. I'm also going to press Ctrl+T to add the Texture  Coordinate and a Mapping Node. And now I'm going to plug Object into Vector. I'm using the object  coordinate because it's going to place the texture more evenly on the object. Now I'm going to  change the Musgrave texture to Multifractal, change the scale to 1.2, set the Detail all the way  up to 15 and I'm gonna set the dimension to zero. Okay, so these dark areas are going to be the rust  and these white areas are going to be

the metal. Now I'm going to add a Colorramp to control the  colors. So press Shift+A search for Colorramp and drop it here. I'm going to plug the Color into the  Base Color of the Principled BSDF, hold Ctrl+Shift and select the Principled BSDF, and I'm going to set  the colors. So this one is going to be 7D391C. I'm gonna add a new slider to  create some color variation, and this one is going to be 79461D. You don't need to use the same colors I'm using, you can just experiment and see which  co

lors work better for you. For the metallic part I'm going to use a gray, so it's going to  be 717171, and I'm gonna grab this slider and move it to something like here I guess. So now we  need to control the Metallic of our material, but the Rust part is not going to be metallic, so I'm  going to use the Musgrave Texture to determine where it's going to be metallic and where it's  not going to be metallic. So I'm going to plug the Height of the Musgrave Texture into the  Metallic of the Principl

ed BSDF. Now I'm going to add another layer of rust, so I'm going to press  Shift+A and search for a Noise Texture. Let's plug the Object of the Texture Coordinate into the  Vector of the Noise Texture as well. I'm gonna hold Ctrl+Shift and select the Noise Texture  to preview it. I'm going to change the Scale to 7, I'm gonna set Detail all the way up to  15, and I'm going to change the Roughness to 0.65. Now let's bring in a Colorramp, and drop it  here. And now I'm going to flip these two valu

es. All right, yeah! I think it looks  good. Okay so now I'm gonna mix these two colors together and to do  this I'm going to bring in a Mix Node. I'm going to change it to Color, and I'm going to plug  the result into the base color of the Principled BSDF. And I'm going to plug this Color into the  Factor of the Mix Node, and I'm going to plug this Color into the A, and I'm going to use the B value  to determine the color of the second layer of rust. Okay so I'm going to set a Color. So the hex

  value will be H3402C. Again, you don't need to use the same colors I'm using, it's just  for reference. Okay, so now we need to work on the Roughness. So what I want to do, I want to increase  the roughness on the rusty areas and make it more shiny on the metallic areas, and to do that, I'm  going to select this Mix Node and press Shift+D to make a copy of it, and I'm going to plug this  Color into the Factor, and this Color into the B. Let me preview this result first. So the dark areas will

be more shiny,  and the other areas will be more rough. So I'm going to plug the result into the Roughness.  Ctrl+Shift and select the Principled BSDF. So I'm going to use the A value to reduce the roughness because  it's a bit too shiny. Okay, a bit more. Okay, so now we need to add some bumpiness. So I'm going to  bring in a Bump Node. So, Shift+A, search for bump, plug normal into normal, and I'm going  to use this color to be the Height. I'm going to select Invert to invert the  bumpiness. I

'm going to reduce the Strength. All right, so now I'm going to add  a new layer of bumpiness. So, select the Bump Node and press Shift+D to  duplicate it. Plug normal into normal. So now I'm going to use this Color  to be the Height of the Bump Node. Okay, so now I'm going to disable the Invert. Okay,  so let me reduce the Strength because I want it to be really subtle. All right yeah I think it  looks good. And that's it! Rhis is the final result. As it's procedural, you can easily customize i

t, so  for example you can adjust the bumpiness. Like this. You can change this color to make  it look like a really old metal. And you can also use this slider to increase the rust. You can use this one as well. Like so. And that's it! So, if you enjoyed the video, please hit the like button and subscribe to  the channel.
