Light Shaft

The local light shaft is a volume shadow simulation based only on the Depth buffer.

LightShaft_Step : is an integer value that corresponds to the number of samples used to make the blur 

LightShaft_BlurDistance : is the total offset of the radial blur

LightShaft_DrawDistance : is a control value that allows to stop the lightshaft on surfaces that exceed a certain distance, to increase in the case of a planet, and to set correctly in the case of a closed environment

LightShaft_ScreenMaskRadius : the lightshaft has a mask to avoid the cut in the edges of the billboard plane, this value is the radius, 0 to 0.5

LightShaft_ScreenMaskDensity : this value is the density of the circular mask 

LightShaft_Tint : is the color of the light shaft

LightShaft_Power : allows to change by an exponent the gradient 

LightShaft_Boost : allows to change the final intensity
