Attempt to recreate this impact with unreal materials

Good day, i begin a number of months with vfx and un this second i attempt to recreate the results i like or i hace curiosity.
I Noticed this shader from jettely on Twitter and take a look at yo do It myself. Possibly i search with the wrongs phrases however i can’t discover assist so i submit right here.
To begin with I can’t create the Up face with sdf on unreal materials and at this level how am i able to match the middle with the feel? I want customized node for recreate this??
Allí assist are welcome thanks for learn at this level :slight_smile:

The shader are from jettely anda that is the unique tweet

To be trustworthy, I by no means used UE, I solely use unity and so far as I do know, you will have to make use of customized capabilities in some unspecified time in the future on this shader however possibly the UE node system has extra to supply, so I’ll clarify the tactic, basically, and if you wish to get deep at it, let me know.

  • The shader makes use of a way referred to as signed distance discipline (SDF) rendering to create the looks of a fruit. SDF rendering includes casting a ray from the digicam by means of every pixel on the display screen and calculating the gap between the ray and the floor of the thing. The shader then makes use of this data to calculate the colour of the pixel.


  • The shader additionally accommodates two capabilities: “planeSDF” and “sphereCasting”. These capabilities are used to calculate the place of the thing’s floor in 3D area.

  • The “planeSDF” operate calculates the gap between a degree in area and a aircraft outlined by the user-set “_Edge” property.

  • The “sphereCasting” operate casts a ray from the digicam’s place into the scene and determines the place it intersects with the thing’s floor utilizing the “planeSDF” operate.


I might try one thing like this utilizing this shader community I created some time again due to a tutorial by CGHow. Hope it helps.

I believe the one strategy to make that form of boolean operation on one shader with out utilizing methods with a number of ones is with Raymarching and costume HLSL code. Right here is a good introduction video on the subject:

There may be additionally great collection for HLSL coding from Ben Cloward.

I hope it helps.
