occlusion mapping this was a request from blend space lab I might make a better one

later in the future so this is all I have right now.So to make this you need two textures

first one is the height and the second one is the texture.I made both of them in substance

designer this is the fluid noise texture you get from the noise

tab so you can get that from here .So this is the fluid one and this is the fur one so

I just increased the level a bit then blend them together and inputted them into the height

map and for the fur .I just used a gradient map and changed the color a bit and inputted

it into the base color then I exported it out and imported into the unreal engine .So

we are going to use parallax occlusion mapping to make this fur so the first thing you need

to do it create a material so for that right click and click on material .I will name this

fur underscore mat.then open it up then drag and drop the height texture then drag and

drop the fur texture we need to duplicate the height texture two

times now I will convert this to a texture object now we will right click and type in

parallax occlusion mapping so we get this node first we are going to input this into

the height map texture then we have to do something here so here you can see height

map channel since we have a grayscale image all the channels will be our height map except

the alpha so if I check blue you can see all of the channels have the same image because

we have a gray scale image so we need to input a vector 4 here so for that press and hold

4 and connect it here so we can change either 1 for. We can give 1 for R or G or B to select

the channel which the height map is in. If we use Packed textures then the red channel

might have the height texture the blue channel might have the roughness map and the green

channel might have the ambient occlusion we are not using packed textures here. So R G

and B all have our height map so just give one to any one of them

now we need to create a couple of parameters .We need three so hold S and click I will

name these height ratio then I will Name this min-steps and I will name this max steps and

I will connect height ratio to height ratio and give it a default value of .2 and for

the min-step I will connect this to min step and give it a default value of 25 and now

I connect the max-step to the max-step and give it a default value of 120 I will show

you later what these three things do now we will give a texture coordinate so for that

press and hold U and click so we get this texture co-ordinate now press and hold M and

click so we get this multiply and connect this to the multiply and connect this to UVs

now we will create a new scalar so press and hold S and click so we get this scalar parameter

and I will name this tiling and I will give it a default value of one then I will connect

this to B now I will convert this to a texture object

.We need a normal map and I could create the normal map for the substance designer but

I decided not to I will show you a trick to create normal maps from the height map so

convert the height map texture to a texture object now right click and type in normal

from height map and connect this to height map t2d and we will duplicate this by press

control + W and connect this to the height map channel selector if we preview this we

can see the normal map I will connect this to the normal map and from here the pixel

depth offset goes to the pixel depth offset here and I will give roughness a value 0.9

so it is very rough now I am going to connect this parallax UVs to this and also to the

coordinate of our normal from height map then I will add a hue so right click and type

in hue so we get this hue shift connect the texture here and connect this to the base

color to we can change the color later so we need to add new parameter here so press

and hold S and click so we get this parameter and connect this here I will name this hue

then we need to add the rim lighting effect so for that we will use a fresnel node so

right click and type in fresnel and we will lerp press and hold L and click so we get

this lerp and connect the alpah to and connect this to the base color and connect this on

top and for B we will give a white color so press and hold 3 and click so we get this

three vector and I will convert this to a parameter and

I will call it rim color so we can change the color later.So I will give it value of

white then we need to control the this rim width or like this radius we need to create

a new parameter so press and hold S and click and connect this to exponent and I will name

this fresnel and I will give it a value of 15 so as you can see as I decrease the value

white color will move to the center and as I increase the value we have a very thin layer

of white color on the edge

so I think that all we need to do here So one thing you have to keep in mind is that

when we increase the tiling here this tiling also increases there is a way to fix that

I will show that in a future video.so click apply and save thenI will drag and drop a

sphere in then I will create a material instance so right click and create material instance.Apply

this to the sphere.So you can see the artifacts and if I press play the artifacts wont be

there .So you don't have to kind the artifact .So you can actaully change the paramters

so open it up and I wil give it a nice rim color. I will change the height ratio a bit

so as you can see it will get a bit longer it looks a bit longer you can also change

the tiling so you get finer fur and then you can play around with the max and min. To get

the look you want you can change the color by selecting the hue and changing it so you

can see artifacts in the editor but if I press play it won't be there .So this fur material

tends to do well on curved surfaces on flat surfaces there is some issue.I will try to

make a better fur material later.So this is all I have now I hope you enjoyed it .So thanks
