lumFromAlphaAndLight() purpose?
Hi!

I'm playing around with Gfx settings and unfortunately can't figure out the purpose of the function Gfx::lumFromAlphaAndLight() and how to use it. Do I have to use only DIR_FLAGs like for example DIRF_RIGHT? And what is the range of density_factor? And what is the impact of those settings?
I'm searching for a way to apply this glow effect to my lens flare gfx, so I thought maybe this function can achieve this effect.

Sorry for so many questions, Esenthel, and thanx in advance smile

Hi,

this function is meant only for 3D textures, to calculate the voxels luminance according to voxels alpha, and light direction.

it is used for example in volumetric clouds.
