How To Make Realistic Concrete Shaders In Blender

uh hey everyone so i got a lot of questions on my instagram um about making a tutorial for some concrete shaders so i thought i might just post it on youtube instead of making a patreon because it's more accessible to more people so yeah i got this little folder here which i just picked out some textures from textures.com uh qixel and um some other sites that i found so i'll be using these but you can really use any textures you want and yeah so i'm using a displacement map uh an albedo a normal and a roughness map i also have this basic scene that's kind of preset up this is just an immersive texture just so i can see what what's happening um but yeah so let's get started so usually with albedo just put that here plugged it in see how it looks this is just the base image of a texture it's gonna look really plain um i usually in blender like to use the rgb curves um i actually haven't found an equivalent in different softwares for this so it's really useful that blender has this you can basically really darken your image or really lighten it but it's really really useful in maya arnold and redshift i haven't really found an alternative but yeah it's a big plus for blender in my opinion so then i usually use roughness this is quite a nice roughness map so here you can see you get a lot more um a lot more details already and like different reflections uh you can also control this with a color amp um so if you just put that in here drag it over so the black parts if you bring this up it's going to make it more reflective and bring out more of the black which is the more reflective part and then if you bring in more the whites it brings in more of the non-reflective parts so you can really play around with this you can also make the base more gray and that makes the base reflectiveness less reflective but yeah there's a lot of different combinations you can really do so next i'll probably go with the normal or bump map i usually go with a bump map um so plugging this into height and then from normal to normal so as you can see this looks extremely gross at the moment so in blender i think you want to turn down the distance because it saves on detail so i usually have this like really low 0.01 and you kind of get very um a very subtle effect as you can see this is still kind of looks low quality it's because it's a 2k texture i think so what i usually do in this case is i just scale this up a little bit to like even sometimes like 7 or 11 it really depends on the normal map as you can see that's tiled a lot and you get a lot more um it looks a lot higher quality in my opinion at least so then another detail that's really cool that i like to add is displacement maps so this is usually just displacement and then you put this into the height and we need to displace over here i don't usually use blender as well coming back to me as i do it but yeah okay and then i think we also have to enable it somewhere in here [Music] i think later so it's make sure you just uh set this to displacement and bump um and then it's going to jump down like this and i think the shape by default and blender isn't really subdivided so we can just add a subdivision surface um set this to simple and then just do like 10 uh you want to go easy on this side because it's going to kind of go harsh on your computer so then just hit the scale to something low like 0.1 you get this kind of variation happening where the mesh actually comes out so we can set this zero one maybe uh this is also a lower quality texture so i do like to tile these it's like three so yeah you can see this is already looking pretty nice to be honest um i reckon we can get some more displacement such as 0.5 to that um and maybe we can also increase the reflections a little bit but yeah this is kind of a basic concrete shader and um you can really play around with this if you wanted to oh yeah and also if you want to get variation on the displacement map i just tried this before it did seem to work um you can also plug in a color ramp here and you can slide the black up and it will give you some different uh variations of how much of the displacement shows which i also found pretty cool so if you wanted less of the bumps to show as you can see as you slide this up um it's it shows more of the flat parts of the texture and then the opposite is true for the white part of it will show the stronger whites so this is a bit too far in my opinion but um yeah something like this is pretty nice um this one isn't the most reflective but um you can easily uh customize this to your liking but yeah this is a pretty basic rundown of usually how i do my concrete textures um i usually spend hours on this to get like the perfect look that i want but um yeah it's not too difficult it's just really the basics and just playing around with it until you get a result that you like um and yeah i just wanted to share that so i hope you guys liked it and you can find it useful um yeah
