Currently, you can enable or disable this in the mesh preview kernel to either show your background or not, but when you switch it, it restarts the render.
Does it have to restart? I thought all the information is still being gathered. Is it possible to make it so you can enable/disable it while continuing your rendering?

Thanks

+1.

To save memory we deallocate the buffer storing the alpha channel, which means the alpha information gets lost when you disabled it. It's 4bytes per pixel, i.e. on a 4000x2000 pixel image, we are saving ~32MB. We could add a second alpha option to the imager which allows you to enable/disable the alpha channel in the tonemapping, while you leave it enabled in the kernel.

Would that makes sense?
