System information

Issue description

Baking VoxelGI causes Editor Hang, I'm trying to bake VoxelGI and clicking Bake GI Probe causes Editor hang and I can't find any workarounds for this.

Steps to reproduce

1. Add VoxelGI
2. Set Extents
3. Click Bake GI Probe.
4. Observe the Editor hang.

In my case, after I hit Bake, the editor sits for a moment (hangs), then it again starts working. But it seems that it didn't bake anything and also pushes a error spam...

In the output panel:

In the console:

It seems to confront with the new Rendering Device

@sairam4123 @INdIEDeV016 Can you upload a minimal reproduction project? Despite trying this on several projects with both baked and dynamic meshes, I can't reproduce this issue on 4.0.dev.custom_build [52b7d5f] (Linux, GeForce GTX 1080).

[sairam4123]

I can try it again, do you have a prebuilt version for Windows?

@Calinou Alright, it works in v4.0.dev.custom_build [2681d93b8]. But when I changed the gi_mode property of some MeshInstance Nodes and after clicking bake in VoxelGI, the editor suffered lags. The FPS fell below 5. Edit: Can't reproduce the error anymore 😅

I can still reproduce this issue on build 702ffc624, the editor hangs and spits out this error.

OS: Windows 11 21H2
Graphics card: NVIDIA GeForce GTX 1050

@Calinou

Will test out on a new project.
Can reproduce on a new project as well.

It looks like a Windows 11 specific error

Minimal reproduction: (Even though there is no error in my project for v4.0.dev.custom_build [2681d93b8]):

1. Start a fresh project
2. Click 3D scene button
3. Add 2 MeshInstance3D Nodes
4. Configure one mesh as a Cylinder other a Plane
5. Change the gi_mode of Cylinder Mesh Instance to dynamic and other (the Plane) as baked
6. Add VoxelGI Node and click Bake GI

This works.

This works.

So, no need to reopen this issue, right?

It shouldn't crash if I didn't set the global illumation to baked or dynamic right?
Maybe there should be a configuration warning.

Didn't test that aspect

[INdIEDeV016]

@sairam4123 Well, it seems VoxelGI won't work if we don't set any gi_mode for the MeshInstance3D. (i.e set it to disabled)

The warning is shown even if I click Bake GI Probe

[INdIEDeV016]

Oh yeah, but now if I change the gi_mode from Disabled to Dynamic for the Cylinder, then the editor starts performing very badly. It starts using 100% of my GPU in the Task Manager

This is a known issue, see #55359.

Found some errors. I don't know if it's related.....

The layer manifest files message is unrelated – it's being tracked in #45725.
