UE5.4 procedural Lava & Magma Material

Preview of the final product
Lava material with full controls over the size, shape, and speed. Can transform into Magma with procedural harden generation.

Reference and Idea Summary

Creating a magma material
I found this cool down magma material on quixel bridge

Using the two deformed noise Map as mask to lerp two orange color

Using the AO Map as mask to lerp Lava and the rock to make magma

final result

Vertex color & flow map
Connecting the vertex color to height lerp to merge the materials

I am using two channels here because I want to control the harden and the melted part of the magma

I want the magma that can move at different direction to simulate the movement of the magma in real life.

Flowmap function, credited to Ben Cloward and his amazing flowmap tutorial

Final result

Distance to the nearest surface
Connecting the SAME custom parameter to lerp all the ice and water materials

Finished

Complete Material Graph
The magma is now complete and looks realistic. It can transform into lava using a single parameter slider and has many other settings to alter the speed, shape, and color of the magma and lava
