Well, I saw this post on twitter :
Will I be able to do that in Unity with Shader Graph ? We will see. I am not really good in Shader Graph, although I did some previous shaders with it and always managed to get what I wanted. (Reminder to myself : Post them here)
STEP ONE
Good. Let me just start Gimp and do something like that. So in the Filter > Render -> Noise menu there are „difference-clouds“ which is exactly what I was looking for but sadly not scaleable or anything. So I took Plasma, desaturated it and did a slight gaussian blur on it.
Step Two
Right. The animation direction is top-right. So let me do that in Unity. After totally black out how to this () I remember how to do it.
Using time to move the uv offset and multiple time by -0.5 so it scrolls in the right direction in the right timing. (the uv is the image that maps the surface 3D positions to a point on the 2D texture, for those who don’t remember). Ah I forgot one step you also have to set the tiling to 0.1 so it zoom big into the texture.
STEP THREE
All right. I use a Blend Node with Screen Mode to do that. Not sure if that the right mode, but as I remember from working with Substance Deisgner, Screen Mode is basicly mixing two textures together.
STEP FOUR
Well ok, on it.
Done. 🙂
STEP FIVE
Uh, well, ooook. XD
Here we goooo.
STEP SIX
If you say so. 🙂
STEP SEVEN
So I have no clue atm how to do this in Unity Shader Graph. Buuut I think the Replace Colors Node is what I want and yes this did kinda work out.
FINAL STEP 8
All right, this translated into shader graph :
Conclusion
This was a quick morning experiment, and it does not look like the original. At least not yet. But it was worth the try and it certainly is something. I will try to perfect it at a later time. Then I also will make the shader graph asset downloadable. Shout outs to the orginal author of the tweet ! XD
