Wondering this myself, seems like a pretty bizarre change to do on purpose. Or at the very least get some suggestions as to how we can get a nice glow going without just making our emissive lighting turn white/purple.
Totally agree. Why this behavior ?
For the record, the new glow behaviour isn’t an issue for me because of how it works. What bugs me is having to re-tweak all glow values everywhere in the game, while other UE versions usually didn’t break content.
Yeah, that can’t just be “by design” since it breaks all current content. If it is by design, then at least every material needs a checkbox where you can check if you want this new behavior where an emissive blue is getting purple and later white, but that checkbox should be disabled by default for every material that was created before 4.15.
But it is an issue because of how it works, you can no longer get the look you had before. It is impossible now to get any saturated color that’s causing a lot of bloom. For that it has to be multiplied by ~20, but once you do that with any color its just something like white. So you can’t have a strong glowing blue or red material now, they will no longer be blue or red.
So the issue is not only that you would have to redo all your materials, but also that its impossible to get the look you got before.
What is the reasoning behind Unreal Engine Issues and Bug Tracker (UE-41065) ?
It requires a whole bulk of changes to adapt to and limits artistic freedom in achieving required look.
I realy hope 4.15 has the promised Datatable variables when it comes out of preview phase! Compiler time increase makes me too happy allready!
Thanks for the reply.
So, the problem with resetting was because I had a virtual joystick and a g29 connected at the same time. So, it seems like the plugin can’t handle multiple joysticks/steering wheels at the same time. When disabling vJoy, the g29 works as expected.
If I understand RawInputSettings.h correctly though, you’re supposed to be able to set an “Offset” config option, that doesn’t seem to work.
+AxisConfig=(AxisKeyName=“GenericUSBController_Axis3”,AxisProperties=(DeadZone=0.000000,Sensitivity=1.000000,Exponent=1.000000,bInvert=True,Offset=1.000))
Inverts the axis, but doesn’t offset it.
I think I saw what might become a bug in RawInputWindows.h, the FAnalogData constructor that takes arguments doesn’t propagate InOffset to Offset.
I can’t see that constructor being used anywhere though, so I guess that isn’t the cause of the issue here.
I need the Offset option since the pedals goes from 1 in default to 0 in pressed down (-1 to 0 in inverted) and the steering wheel’s range is [0, 1] instead of -1, 1]
I guess this should go to the answerhub instead though. Will create a post later.
Can anyone explain why https://issues.unrealengine.com/issue/UE-39216 is marked will not fix?
4.15 p2.
There is a problem with MSAA and using masked materials. I made a post on Answerhub.
Thank you very much Dev team
Looking forward to upgrading to 4.15!
Downloading now to take a look! Good work, as always guys! 
Have you guys done anything in the Post Process? The colours are a bit darker (or the contrast higher, I dunno) than in 4.14. I haven’t changed anything in my project.
Default tonemapping was changed to the film-looking one, with higher contrast. See the talk about emissive color, it’s the same thing.
Thanks for the information!
I found a bug:
When providing a Material Slot name that does not exist on the Mesh, the Engine crashes.
I feel like i’m missing something. Probably a noobish question but, i grabbed the source on github, i can compile and make it work without any issue.
Now i would like to add a thirdparty, i put it in Engine/Source/Thirdparty, it has a sweet XXX.Build.cs in it that works in 4.14.3, but it seems that it never gets read in my 4.15 build, and the lib isn’t added.
I must be missing something obvious.
UPDATE!
We have just released Preview 3 for 4.15! Thank you for your continued help in testing the 4.15 build before its official release. As a reminder, the Preview builds are for testing only, and should not be used for the active development of your project.
For a list of known issues affecting this latest preview, please follow the links provided on the first post in this thread.
Cheers!
