URP raw image transparency problem (Linear vs gamma color space)

[wahntin]

Got a reply from a bug report I made:
http://fogbugz.unity3d.com/default.asp?1239748_4fsovmbisqj86vvt

Looks like the reason is that URP uses linear color space by default and the default render pipeline uses gamma.

See Unity - Manual: Linear or gamma workflow

Doing custom UI shader seems to be a good workarround for this:

Linear space for scene, gamma for UI?

Good solution, but i have changed your function to color.a = pow(color.a, 2.2); and now the gradients in UI sprites look mush better. 2328504–157215–UI-Default.shader (1.77 KB)

I don’t get why this is not done by unity by default, though.
