언리얼4 팁 - 얼음물 유리잔 쉐이더 제작

Hi guys,
First time doing one of this contests :smile: Mine will be kinda boring since I’m making a frozen glass of water but I was intrigued by thinking about the shader I could make for this.
Here is the reference video for this FX:

 

frozen_glass_gif_02

 

My plan is to first break down each of the elements:

 

ref

 

(There’s actually more then i wrote down but this are the main ones)

 

I will build each of those elements with their own parameters and use sliders turn on/off each element with blueprints.

The stretch goal is to hook up each parameter to a single slider. For example: I want the cracks to start when the first fresnel slider is at 0.5. I’m not sure yet how I will approach this. I’m thinking either Unreal material custom script or with blueprints.

 

Easy stuff first

 

frozen_glass_02

 

Added a secondary layer for fresnel (freezing fx).
This gave me a much better result as you can see in the gif comparison:

 

before_after

 

Before:

glass_before

After:

glass_after

 

Adding ice cracks. All textures that I’m using are from a giant library that I have on my disk which has either my textures or something that I got on the internet. I’ll try my best to find sources for all the textures I end up using (if any) because most of them are place holders which I will later create in Designer.

Got most of the main elements done:

 

glass_08

glass_09

glass_graph

Just realized I need to calibrate my monitor at home so colors might be slightly off.

 

 

 

I’ve been really busy for the past couple of days but I made some progress today.

glass_14

I wanted to make everything inside of the material instead of using blueprints just as a challenge.
I went over every slider and wrote down the range I wanted for it. Then I used sin with some basic math to make it move in that range.
So in this example I wanted the first fresnel to go from 0.2 to 0.8. I connected this to exponent input:

 

glass_15

 

For the ice cracks I wanted them to start when the glass is half way frozen. I used the IF node to tell the strength multiplier to stay at 0 until sin > 0.5.
