[Daz Studio] Displacement Maps. WTF are they?

hello mate in this video we're going to have a very quick look at displacement maps before i get started a huge thank you to everyone for subscribing and hitting that notification icon that really helps me out and an even bigger thank you to my members and patrons your names will be running across the bottom of the screen at the end of the video if you are interested in supporting the channel visit patreon in the description down below or simply join the channel by hitting the join button next to the subscribe button so what is a displacement map a displacement map is basically a grayscale image where black equals zero white equals one and everything in between is a value in between basically and that tells the modeling software in this case dash studio how far or what percentage of the maximum displacement a pixel needs to be displaced in either x y or z direction depending on which way the the object is facing or which way the surface normal is so for example if we have a plane let's just create one here i'm going to create this a 10 meter plane 540 divisions across the reason i'm choosing 540 is because the displacement map i'm about to use which just happens to be the depth map for mount everest funnily enough so if we go to displacement here in the surface properties you can see there's displacement strength so i'm going to go ahead and i'm going to choose the displacement map that i've got here and as you can see at the moment it says displacement strength so we're just going to change that to one and then some other values are going to appear now minimum displacement in this case for this depth map needs to be zero maximum displacement i'm going to set to be approximately 80 centimeters simply because this is a one two something is very very small scale model when we hit return nothing seems to happen and that is because this is a surface property so in order to see what we've done we actually have to go into nvidia ira and then lo and behold if we change the base color to mid gray so that we can see that a little bit clearer you can see now that we've got there a very small scale model of mount everest and we can also reduce the glossy layered weight so that that reduces the glow even more but there you go you can see in ira mode the displacement has created this scale model of mount everest now there's no reason that we can't crank up the scale of this model and let's say let's give it one 10 000 scale and then we're going to have to create a camera or switch to the camera that i've already got in here and look down our model it may not even be visible there we may actually be below it here we are you can see there there is some there are some weird shapes over there so we need to put this camera at a translator probably of about 2000 let's see if that does it that might even be too low still yeah you can still see that we are underneath the mountains let's go to 10 000. now you can see we're above our model and we're up in the well we're pretty much at the peak of mount everest by the looks of it but that's essentially what you can do you can use this displacement maps to apply them to a massive plane and create landscapes if you so wish but bear in mind the displacement map is not going to make the geometry visible or rather the height of the object visible in the texture shaded you're going to have to use the nvidia ira map as a preview to actually see what your geometry is going to look like so there is a case for using this sometimes and a case for not using it other times depending on how accurate you want to be but you know pretty nifty trick anyway if you just want to create some funky landscapes in the background that don't actually require you to interact with them then this would be ideal you can put mountains or hills in the background maybe have a black spot in the middle of your height map so that the area that you're actually putting your models and doing your rendering is still um not got a height map applied to it so you can still work down at plane zero and then just have like this is mountains in the background or something like that either way pretty nifty i hope you've enjoyed that let me know what you think in the comments below and i will see you in the next one but until then you take damn good care of yourselves alright bye bye you
