All light sources emit white light with RTX on

Steps to reproduce

  1. Enable RT and find a dark area

  2. Place down any light source that would normally emit different coloured light (depending on resource pack)

Expected result
Light from sources such as torches should be a warm colour as they were before (again, depending on the pack)

Observed result
No matter what, all light is bright white

Impact

Looks absolutely awful. Below I attached a screenshot of what my house looked like in 1.19.51:Β

Also affects redstone and soul torches.

It seems the file in {PATH}/data/renderer/vanillalights.json controls these point lights (except soul variants). This is an unmodifiable area and all color values are set to #FFFFFF which would be white light. If we give ourselves permissions to edit files in WindowsApps directory (where this file resides in a default install) we can change the colors properly. By chance is this going to be an editable value in the future with a resource pack?

by any chance, could you upload a fixed version of the file as a temporary fix?

Nepnep, under normal operations of Windows, you cannot modify where that file is installed at (WindowsApps) and doing so can break apps that use the Trusted Installer profile (Even a copy/paste overwrite is forbidden by default in Windows). For example, my Xbox games app broke and I needed to do a clean install of Windows to fix the file integrity after giving my user permissions to modify files in WindowsApps directory.

what I would do is instead modify the dir as trustedinstaller instead of giving your user access to the windowsapps directory, its a bit of a procedure but its better than white torch light lol

Thank you for your report!

However, this issue has been temporarily closed as Awaiting Response.

What RTX resource pack are you using? Could you please attach it here?

I’ve attached Defined PBR, but any resource pack that supports RTX should be affected.

Added a vanillalights.json with "proper" color values. (Proper in quotes due to the hue might be off what Mojang considers their art direction for these lights. This is closest I could find to how the lights were before this update.)

Edit: As said before, this is in a protected directory. I highly suggest against using the file, but provided it for those who don't mind the possibility of borking their windows install to fix a few torches/lanterns/rods. It's also provided to show mojang this is the root of the issue. (this file making these lights appear white, not any third party addon like a resource pack being the issue.)

Just want to add that if the solution is to modify the game config files, one can use the unofficial launcher for bedrock and you will be free to modify anything. The game runs exactly like official launcher would and that’s what I have switched to when testing different version of dlss file.
