    I feel bad about even needing to post this.
    But I'm stuck in unity 2019.3 and trying to bake lighting.
    I'm using the indoor lighting corridor demo.
    The lighting is taking a very long time.

    Are there some general tips to speed up baking time?
    Thanks!

    Does this reproduce in other projects? Keep in mind that corridor lighting example is a very old project that was authored for Enlighten baked GI.

    sorry for the half necro-ing but is there a solution?
    2019.4.13f1, URP 3.1.0 here
    (Ryzen 3900, RTX2080 ti)

    GPU Progressive is not doing anything
    CPU Progressive(19mrays/s) is just so slow for a simple scene


    Edit:
    After waiting for about 10 minutes unity suddenly identified the baking device and did it in 22 seconds on 190mrays/s


    but still it takes a long time to just identify the baking device :|
    + a lot of unity loading times

    19mrays/s is not bad for CPU.
