Blender Mist Pass Tutorial

hey what's up today I want to show you how to use the Mist pass in blender to make mist and I'll show you an animation I made recently where I used this method and I'll show you a before and after so you can see the sort of uh the thing we're going for and to do this you need to activate some settings first off you want to go to this view layer tab here and you have this passes Tab and under data there's a Mist box so check that and then go to your camera select the camera and select this icon here and then under viewport display you have these two boxes that you want to check and when you check those you get some lines here you'll get some indicators of where the Mist starts and ends but to actually set the Mist like where it's it's starting and ending you go to world so there's a lot of tabs going on for this but um here you have the Miss pass so the start if I change that you can see this little dot going back and forth I usually just set it to the start or to the origin of the camera you can set it like further ahead if you want I usually go with Z MERS there and then the depth is the end of the Mist so you can see this other dot here and yeah I usually cover the entire scene so you're not going to see further than this wall you have to render one frame of your scene to see what you're doing because uh we're going to work here in compositing so here I have one frame of the animation and I think you need the no angular to do this but if you control shift click on this render layers node you'll cycle through these so here it shows the image now it shows the alpha the Mist no it doesn't actually okay that's actually only going to show if you have the backdrop activated okay well this is what the Mist pass is it shows it generates a kind of depth map so the the closer it is to the camera the more black it's going to be and the further away it's going to be uh it's going to be more white so that's what the Mist pass is and you can use that to to make Mist so let's do that I have the compositor window here and then I okay so it usually comes like this and then I press this corner here and oh and then I drag it out like this so now I have two compositor windows but then I make this an image editor and then here I search for render result and I get this it's just a a nice and easy way to edit your render all right so I'm going to delete that I don't need that but then I'm going to add a mix color node I'm going to put the image in the first input and then the Mist is going to go into the factor and then the image back into the composite and now we have this Mist but um we kind of want to edit this so if you select this other color here at the bottom you will be able to select the color of your mist and and for this scene I went with something that was like kind of blue something like that you can change the thickness of the Mist or kind of the opacity by adjusting the brightness here so if it's completely black oh they actually oh wait I have to do something you actually have to set it to screen screen or lighten I think both works but I I think screen is best and then okay so if you set it to Black there's no mist and then you can you know dial it in and there will be more and more Mist so that's uh that's kind of it another thing I learned recently is that you can uh you can combine the Mist with a noise texture to make it look uh less like a just a depth pass and more like actual mist and uh yeah somebody in in my Instagram comments told me this so that's cool and let's try it and then you want to add a texture node but you need a a texture so go in here to this icon texture press new and then select clouds and now we have that texture it's just called texture you can rename it here if you want then add another mix color node and you can hook it up like that and then you connect the value here from the texture to the actually the top input and the Mist should go into the bottom input and then you set this to multiply so that the dark parts from the cloud texture are going to come through and uh now you can see there's some more texture there uh you can also adjust this I think it's kind of stretched on the x-axis so we want to make it a bit more wide you can see there's some more texture going on there now and I would also increase the depth it's kind of hard to tell but that just makes it a bit more detailed you could add a color ramp here probably if you want to make it a bit more contrast like that looks could look cool but that's just another way of adjusting it I guess and another nice thing is that you could animate this so if you set some key frames on this the mist could move like this which is pretty cool so yeah that's all I wanted to show in this video bye-bye
