4.19 Physical Lights

[Nocturness]

Is the new “lighting academy” video of physical lighting coming?I need some explanation and you’re the best on this

I kinda like it! There is one big BUT from my point of view though…and that is that most people dont have a lightmeter at hand to read the lux when they might capture a sky. Or what happens if you just buy skies from CGSkies.com? You dont know any lux readings as the image data is all you have. So the system needs to work without the need to buy fancy and expensive hardware.

I think its a great option, but it should be just that…an option. There needs to be a working system that doesnt need you to specify that.

In Frostbite, its actually that way that the skylight intensity also adjusts the brightness of the HDR image visible on the skydome (hard in Unreal since they are decoupled from each others…both approaches have ups and downs), so they are linked and thats already nice! However, we still only rely on the candela readings from the skydome as the actual candela values mean nothing cause different images could be captured differently. So we often have that situation that one sky is quite bright and another one quite dark and both are set to…like 5000 cd/m2 in the editor. So again, just measure the stuff on the dome directly and be fine

Cheers!
