    I noticed when attempting to use a "sample gradient" node that the colors I chose (assuming hdr) were only correct if I didn't use a random number [0,1] for time. If I did, then the interpolation between the colors exhibited rather odd behavior. Is this intended or expected behavior? :) As a note, the result with a set value is emphasized, but it is to demonstrate the oddity and not necessarily what I am going for :p

    Unity 2019.3.0f3, HRDP 7.1.6

    For anyone coming here in 2022, I fixed this issue by first setting the color with a gradient (where HDR didn't work for me) and then added a multiply color node which was white with an HDR value. It's not a perfect work around because the HDR value can't be set over lifetime but it's better than nothing for now :)
