I don't know why I've only just noticed this, or what I must be doing wrong
Without any lamps or objects in my scene, if the World is set to white with a value of 1, then in Cycles it is white but in Lux it is grey?
I'm not using Filmic. Is it generally best to use Filmic? and are my settings (attached) good to go?
Screen shots attached.
Thanks

Make sure autolinear tonemapping is disabled in the camera settings and the tonemapping scale is set to 1.
In color management, the exposure should be set to 0 (default) and gamma 1 (default).
If you use filmic, the image will still appear grey in this case, because a value of 1 is technically overexposed if you assume 0 = black and 1 = white, and filmic corrects for overexposed values.
But if you left click a pixel of the rendered image in the image editor, you will see that the true value is 1.

if your tonemapper is set to autobrightnes then you are seeing grey balance, autocorrection exposure.
go to your camera settings - tonemapper and disable autobrightness. try camera settings and input some realistic values.

Thank you for your responses.
I almost always turn off the camera tonemapping, but this is happening without a camera?

If you have no camera, the following imagepipeline is used as fallback: https://github.com/LuxCoreRender/BlendL ... ine.py#L84
Autolinear tonemapper with scale 0.5 (the default if you make a new camera).
