🔥 Add grunge from ANY IMAGE to a material - BLENDER Shading Tutorial

Add Grunge to PBR Materials With an Image
Here's a Blender shading tutorial for how to add grunge onto any material using an image. We can use almost any image and mix darker parts (or lighter parts) onto the base material using a Mix Node. We will also cover how to have the image texture affect the roughness of the underlying material so we can make the grunge appear wet or less reflective. We will also learn how to use a second UV map to control the grunge independently of the base material. With one image texture we can add infinite combinations of grunge to our materials in Blender.

Thank you so much for this! It was really helpful in understanding how to add grunge and dirt over materials !!!!

[@Brandon-3D]

Awesome, thank you so much for the feedback!

[@MarkCorder]

Fantastic and very useful! I'm using this from now on, because even a tiny amount of it can add a lot of realism! 💯

[@Brandon-3D]

Thank you and I completely agree!

So hype fr👊😉✌

5:19, instead of UV map, we can also use texture coordinates.

[@Brandon-3D]

Thanks!

[@luisachadinha4465]

Would this work with lightmaps to? I baked the lightmaps and it a separate texture. Can I add that like you did in the video as a shadow?

[@Brandon-3D]

I have no idea. Don’t really use them but I’m curious to know if you try it.

[@jamesc5801]

You could just add another UVMap and have a seperate one for both the lightmap, and the grunge map I believe. If you're importing to a game engine you should in theory just be able to match the UVMap slot and it should work. I think engines like UE might use a certain UVMap slot for lightmaps by default, so you'd want to avoid using that for your grunge. Having many UVMaps in your shader isn't that expensive as I understand it

@@jamesc5801 thank you!

[@Mark_Tullium]

Is it possible to find some free high-quality grunge textures on Internet?

[@DamilarePadre-fe8eu]

A 5 year old child could follow the tutorial with ease👍👍💚

Put "Even" before, it creates confusion 😂 criticize or compliment 😅
