Official Progressive GPU Lightmapper preview

When's the 2023.2 alpha out then?

 

It was released today.

 

I tested it with
https://assetstore.unity.com/packag...sets-for-pc-mobile-industrial-set-v3-0-101429
The only change was from Enlighten to GPU Progressive. The setting was 4096 on lightmap size. Since the graphics card only has 4GB, the lightmapper switched to the CPU. I canceled by pressing cancel and changed the max size to 1024 and GPU. The bake failed despite this and passed to the CPU. Everything works if I restart Unity.
Tested with 2019.4.30 and 2021.3.21.

 

Using Unity 2023.2.5f1
We only bake probe volumes

should I worry about this error OutOfMemoryException: Out of memory in BLAS buffer (stack at end) It goes on to complete but as far as I can tell non of the baked light probes are providing any global illumination, the render debugger global illumination shows as a grey world

When I select a light probe in a scene it says the Probe has never been baked or has changed since the last bake

Strangely I get the same error selecting CPU lightmapper

With GPU I also get

OpenCL Error. Error callback from context: CL_OUT_OF_HOST_MEMORY error executing clFlush on NVIDIA GeForce RTX 2080 Ti (Device 0).

and

Light baking failed with error code 3 ('BakeJobInitializeLightmapData' failed because it ran out of memory.).

We do have a about 20 scenes covering about 3km x 3km with about 24 terrain objects and a lot of dressing..

Can anyone guess what's happening here? I would have thought GPU Lightmapper could handle a scene like this.
