Hi! I'm making volumetric lights and I've got spot lights working using the spot light's spot angle. But it doesnt match the gizmo unity shows. Where can I find how unity is using the spot angle for the gizmo?

oh awesome

#

ok so im sending some data to the gpu about a spot light and the data includes its spot angle

#

actually wait no give me like 5 mins i think i had it wrong the whole time hold on i might not need help

#

ok so this is the spot angle at 1 radius and this is it at 180

#

i need to get the angular difference between where the light is pointing and another one to choose whether to render the light

#

but the angles dont actually make sense
