Lightmass GPU. No bounces when baking

I have a 5070 with 12 GB, a Ryzen 5 7500, 32 GB of RAM, Unreal Engine 5.7. I’m trying to bake lighting, but only the direct light is being baked — there are no bounces, or they’re not being applied to the lightmaps. Here are the logs.Please help, maybe I made a mistake somewhere trivial or the problem is deeper… I’ve been trying to solve this for 5 days already :persevering_face:

I switched to one version lower, 5.6.1, and it started working right away. Now I just need to learn how to make the light penetrate deeper and be brighter
