levels adjustments and pbr

HAWK12HT · Jun 2015

hey all, since most engines are now working with linear space (unity, Unreal) do we still need to set things right in albedo using levels adjustments or we can just skip levels adjustments al together, as we used to manually play with levels old school days (manual gamma correction) :shifty:

Textures should be in linear space in order to work with unity/unreal ? didn't know that.

uh no for manual level adjustment or textures be in linear space? O_O

I think is no for linear Space. Those engines should have a pass to convert to linear space if needed.

It would be a terrible idea to make textures in linear.

oh ok cool, but what about that level adjustments then

The question about levels is way too vague. Why were you using levels in the first place? You certainly shouldn't apply levels to your texture after you're done to maximize the image range or anything like that.

in unity for your roughness etc - gotta change your texture type to "Advanced" > "Bypass sRGB"

All your textures are on your PC in linear space but displayed with gamma correction to you on your screen, in an engine you just have to make sure telling it which ones should stay linear

Not sure if thats the question, but maybe adds some puzzle pieces

aye Earthquake that same thing, you adjust the level sliders to get the max ranges. Thats what I meant, so cool we still can use those. Hmm I got it wrong then I thought of it as a way of getting brightness out of your texture due to the gamma showing your texture a bit darker.

Shrike, cool man good to know this too.
