    Anyone have issues with baking lightmaps above 1k? Whenever the bake requires more than a 1k map unity switches to the CPU lightmapper when run. Setting lightmap size doesn't help, and setting it to 1k doesn't bake multiple maps either

    Is this just a preview issue?

    Cheers.

    Update - So I've found that setting lightmapper to GPU, clearing cache save then restarting unity sometimes allows me to bake to multiple 1k textures. Still no luck with larger maps.

    It’s because it’s running out of VRAM. It’ll be a bit better in 2020.
