Dear all,
In the Ray Marching materials included in Niagara Fluids Grid 3D (i.e. M_RayMarch_Fire_Ramps) I cannot find the implementation of light scattering due to the presence of small particles in the air, much in the way it was implemented in the previous GDC Pack in UE4.26, for which a specific Henyey-Greenstein function was included in the Density RayMarch node, using anisotropy factor as main input. Given my interest in simulating wildfire smoke, that’s an important aspect for me to cover. Has anyone implemented such type of functions (Mie, HG etc.) or, in turn, does exist such function/node in Niagara Fluids?
If the answer is no, I will try to implement it myself.
Any feedback / help will be super welcome.
Thank you in advance.
