Where to find it

Paths are relative to Assets/FORGE3D/Planets HDRP.

Prefabs/Planet_Lava_01.prefab uses Lava/Materials/Planet_Lava_03.mat on the root Mesh Renderer.

Main settings

Group	Inspector setting and property ID	What it changes
Color	Lava Low _LavaLow, Lava Mid _LavaMid, Lava High _LavaHigh	Set the rock palette across the terrain detail.
Emission	Magma Map _MagmaMap, Magma Color Min _MagmaColorMin, Magma Color Max _MagmaColorMax	Set the fissure pattern and the range of magma colors.
Emission	Magma Power _MagmaPower, Magma Boost _MagmaBoost, Magma Glow _MagmaGlow	Shape the magma texture’s contribution to the palette. Use Magma Glow to scale the emission.
Lighting	Specular Color _SpecularColor, Specular _Specular, Specular Boost _SpecularBoost, Smoothness _Smoothness	Tune highlight color, strength and spread on the lit rock.

Advanced settings

Group	Inspector setting and property ID	What it changes
Surface	Height Tiling _HeightTiling, Detail Tiling _DetailTiling, Normal Scale _NormalScale	Control the size and apparent depth of rock detail.
Emission	Lava Mask Power _LavaMaskPower, Lava Mask Boost _LavaMaskBoost, Lava Mask Tiling _LavaMaskTiling	Shape where fissure emission is visible.
Animation	Distortion Map _DistortionMap, Distortion Factor _DistortionFactor, Distortion Speed _DistortionSpeed	Control moving distortion in the sampled detail. Compare in Play Mode.

Practical example

At fixed Exposure, compare Magma Boost 123.7 and 0. Look at individual fissures. Some glow remains at zero because the masked lava emission still contributes. Adjust Magma Glow for overall strength.
