I have an issue with my eyes that reading light letters on a dark background is extremely painful.
So when I started UE, the first difficulty I’m facing is–a dark theme.
I know UE doesn’t have an option for this, but I have seen a guy has changed the whole editor to white using “Slate”.
After hours of searching I didn’t really get what Slate is and how to use it (or even how to start to learn it)
There are some options in the Editor Preferences: General > Appearance. Not much, though. Apart from that, perhaps a marketplace could help. A quick search does not bring much but I found this:
Even though it may seem like the opposite of what you’re looking for, judging by the screenshots, it could be used to make your own Light Theme. Drop the creator a line and enquire whether this is feasible.
But as you can see, there’s still some things that aren’t easily readable, and that’s because some colors are hard-coded in the engine… I’m periodically trying to make it work, but it’s really difficult, and I already wasted a lot of time on this
You can also light it up a bit while keeping dark theme, but I don’t think it’s what you’re looking for. Here is an exaggerated example:
Unreal Engine 5 has a very flexible built-in theme editor. Just go to Editor Preferences and search for “Theme” and it’ll take you to the Active Theme selector. You can duplicate the existing Dark theme and edit it. It lets you see the changes in real time, which is quite handy, so you can quickly figure out what to change.
