CREATE A PROCEDURAL FROSTED GLASS MATERIAL IN BLENDER V4

hello and welcome to blender bite size in this video I'll be showing you how to make this material procedurally in blender just a quick one to let you know that I have a brand new patreon page come and support this Channel and get your hands on dozens of procedural [Music] materials just a quick reminder before we get started that this is for blender version 4 if if you need to work with blender version 3 because of a computer specs or whatever then please do check back for the uh through the playlist for the previous version of this frosted glass tutorial okay that done for those that are interested this is my scene setup I've got a plane that I've turned into basically a psych I've got an area light coming down the back of that I've got three lights constrained to an empty which I kind of put towards the front edge of the object that I'm going to be shading which is the icosphere and then of course I have the camera in the front so let's switch over to the shading View and actually what I'm going to do is move that object into the center and also the empty and you can see what happens with the lights there they follow that empty because they're constrained to it so let's keep that fairly Central anyway back to the it osphere of course I am using the Cycles Render engine if you using any other render engine such as Eevee I can't guarantee this will work for you now for the render settings I've got 02 as my noise threshold a maximum samples of 512 and I'm denoising using the open image denoiser for the light paths I've basically gone for a default setup so that's this here again any other variation to this and I can't guarantee this will come out the same so just play around and find your settings so I'm going to click on new material now shoved it all the way over here so I'm going to press a and then the period key on my number pad and that will bring everything into Focus here now a lot of the work will be done by this principle Chader which has changed a bit since version three so we'll take a look at that now I do need to enable viewport shading in here so we can see better what's going on there we go uh uh and what I'm going to do is give the transmission a value of one that's going to make it see through basically I think I need to change the background color of the floor there we go so let's go back to the main object uh now we can give it a color but the color is actually going to serve a purpose in this case so I will come back to that we don't need any metallic value here we're going to drop the roughness down to .25 we'll leave the index of refra refraction at 1.45 that's around what glass would be it's kind of around there so you can sort of play around with that if you want a different look oh got a smiley face uh there and that's the main settings further down obviously we've put the transmission up to one the coat Sheen and emission I don't think actually we'll add a tiny bit of coat to it .185 with a roughness of 75 it's just going to give us that little bit extra uh don't need any Sheen for the speculate I'm going to change the distribution to ggx and leave everything set as it is and I'll just collapse all of those and oh excuse my phone what I need to do is basically apply shush I need to apply a color ramp to this with a hue and saturation um node so I can do one of two things I can press shift a as we did before and either find it in the uh menus color WRA or I can click on search and type and search for it but we can now drag a line from an input or an output and we get this little plus symbol and when we release our Mouse button we get the search box automatically so sorry for my phone going off all over the place so there we go color ramp now I'm going to set this first value to8 actually no 0.5 so it's kind of way up on the the value range there and leave that at White and everything else the same there then I'm going to search for a hue saturation value node drop it in here and drop the saturation down to 0.5 these might not seem to have done a lot but if I disconnect them you will see a slight in fact actually no if I change this Factor value you'll see a very slight difference as I slide through that scale basically what this is doing is just dumbing down the scattering in the middle a bit and giving that sort of realistic frosted glass look and that believe it or not is your entire node setup for frosted glass now let's render this out very quickly so you can see uh a finished result and there you have frosted glass now admittedly this is for an entirely smooth orb obviously you can apply it to different shapes so in fact actually if I shade flat you can see that there's faceting going on there and if I disable this subdivision modifier you'll be able to see on there that you get obviously the fating going on so you'll get a different look depending on what you're putting it um depending on your model then if I put something beside it or behind it even let's put a cylinder behind it you'll see that that also plays with the light or the the refraction within the glass uh let's just quickly apply some kind of color to that so you can see lots of things to do and play with when it comes to this particular Shader anyway I hope you have enjoyed that and we'll put it to use in your own projects of course before you go please do
