Last updates
Update v0.12 (04.01.25) - Fixed the issue of duplicate log entries when using the PrintStringToGLS function and other minor bugs.
Update v0.13 (04.06.25) - Added the ability to use GLS_LOGFMT. GLS_LOGFMT is a macro similar to UE_LOGFMT that allows you to format log messages using fmt::format syntax within the GLS logging system.
Update v0.14 (04.21.25) - Tabs can now have custom user-defined names. Filter panels are now resizable via mouse drag. Filter categories now stay visible after clearing logs, with dimmed appearance if no logs are available. Filter categories appear fully opaque if there are logs to display, and semi-transparent if no logs are available. You can now hide logs by category using the eye icon, removing them from the main list. Added bStrictFilterMode setting to switch between OR (default) and AND logic for category filtering.
I purchased the plugin about three months ago for use in both a mobile and VR project. Big thanks for the support on Discord and for the quick fixes to the issues we reported.
One of our main hopes was that the plugin would allow us to view logs directly in a shipping build on real devices and it absolutely delivers on that. Thank you for your work; I know it’s not easy to build something like this.
One area we’re still looking forward to improvements in is VR support. When opening the panel directly in-game, the widget doesn’t render properly in VR, so we’ve had to place it in the 3D world as a 3D widget instead. Other than that everything works great.
Bought the plugin right at launch about six months ago. Gotta say - it was pretty rough at first. Lots of bugs and crashes. Our team reached out to Fergius directly, and to his credit, he fixed everything super fast like, within a day. Massive thanks for that level of support!
Now it works great. We’re using it on PS5 and Xbox, and it’s super handy to test the game right in the living room and see logs on the TV when stuff breaks.
Huge shoutout for the shipping build logs feature that’s a game changer. Without it, we’d have to build special test versions every time, which is a pain.
Also, the UI? Clean and consistent same in editor and in-game, which honestly blew our minds. No idea how you pulled that off, but it’s awesome.
Huge thanks to Fergius for this plugin. It’s exactly what I’d been looking for. Viewing logs directly in builds is insanely useful. Can’t believe Epic didn’t build this into the engine!
Fergius personally helped our team set up logging in shipping builds fast replies on Discord and email, really appreciated.
Pro tip: you can enable logs in shipping, but when making the final build, just add -gls_disable to the build args GLS will be fully disabled. Super useful tip from Fergius that made testing and shipping way easier.
And the update notifications? Brilliant. First plugin I’ve seen with that. So helpful.
Thanks for the plugin! I’m using it on macOS and iOS had to build it manually and tweak a few things to fit our setup, but overall it works great. Support has been really fast and helpful.
One thing I’m really missing, though, is the ability to name each log tab individually. Would love to see that feature added. Really looking forward to it!
Seconding this, works great as a VR logger where you really need to keep the HMD on whilst testing.
I did the same and added it to a 3D widget. Amazing value for money, I’d rolled my own simple limited version before using this but this is night and day better.
The latest update is awesome! Finally, the annoying bugs with tab creation and deletion are fixed. That issue was driving me crazy for a while. Huge thanks to Fergius for taking care of it, and he even added custom tab names! I actually asked him for that, so cool to see it in the plugin now.
One thing that still bugs me a little is when you have a ton of logs and open a new tab, it can take some time to load everything. During that loading period, the FPS drops a bit because the logs are still being created in the tab. Once they’re fully loaded, everything goes back to normal. It’s not a big deal, but it would be awesome if it could be faster all the time.
We use GLS with the team every day, and it’s super helpful. I also love that the plugin shows update notifications right inside the GLS overlay. How did you even do that? It’s such a convenient feature and makes it really easy to stay up to date.
Thanks for building such a great plugin and keep up the amazing work!
