Sadly no, it’s not worth the head ache currently, as most people I assume are exploring this for VR lighting purposes. Currently trying to figure out foliage with Unreal and VR for Quest 2 (the aliasing is a nightmare - best solution thus far is using sprites lol)
That’s besides the point though, unfortunately all we can confirm is the GPU lightmass bake doesn’t carry over to the ES 3.1 shader =\
