Any news on when the hotfix will be released? Just trying to plan ahead.

85

Only build the UE4 project. Don’t do “Build Solution”.

86

I know but I would like to have everything running fine as usual.

87

It does run fine, technically. It’s just that Mac Shader tool is now a part of that solution. I’m sure they’ll get a fix to it, but I’m not sure you ever want to just blindly “Build Solution” on the entire engine.

88

For Static / Stationary Skylight, shadowing on fog will now work out of the box due to the new Volumetric Lightmaps.

For Movable Skylight, shadowing on fog was already supported if you have Distance Field Ambient Occlusion enabled.

89

I don’t think that scene is something we can redistribute, but you can find it somewhere in this thread:
https://forums.unrealengine.com/development-discussion/architectural-and-design-visualization/60547-lets-make-lightmass-epic-and-understandable

To setup emissive lighting, we just applied a bright emissive material to that one mesh, enabled bUseEmissiveForStaticLighting on the mesh, then set NumSkyLightingBounces to 10 in WorldSettings.

Note that emissive mesh lights tend to cause noisy lighting in Lightmass, which you can reduce by making the emissive area larger or jacking up IndirectLightingQuality.

Hi guys.
Can I use C # instead of C ++ code? :slight_smile:

91

No, but you could try blueprints :wink:

92

I completely agree, it hurts to see how Epic is still working on improving static baked lighting. Epic just needs more devs working on lighting and shadowing. Every dev-rendering merge to I hope to find improvements to dynamic lighting and shadowing, but recently, it was mostly all just static lighting stuff (apart from the awesome vulkan improvements, thanks Rolando!).

It feels like is the only one working at lighting and shadows, so whenever he works on static lighting, 0 people are left for the dynamic side. If Epic would have at least 2 devs for lighting with one constantly working on dynamic lighting, that would already be a huge improvement. But I get that finding people with the skills of is very, very hard. I just hope Epic is really trying to.

Support for Vulkan is in 4.16, 4.17, and also 4.18. It gets improved a lot with every engine version. In 4.18, I couldn’t see any differences between D3D11 and Vulkan any more, so Vulkan SM5 is working very well now regarding supported features. Just performence is still significantly below D3D11, so thats for 4.19 and 4.20. But you can already use Vulkan on Windows and Linux, even VR works with it now (SteamVR).

Hi, I have just update unreal but the launcher still saying 4.15.0. How do I update to 4.18?
Thanks

94

Simply make sure that option “Enable Gradle instead of Ant” is enabled in Project Settings -> Android. This is out-of-the-box :slight_smile:

95

hey guys,
Im having here huge performance issues, in 4.17.2 im all the time on the cap of 120 FPS, since the upadte to 4.18 im getting somethung around 8 to 30 FPS.
Im working on a 4K monitor, any idea what is going on ?

96

if I read this right, go to documents folder, find your unreal folders, go to the one you want to upgrade, right click on your .uproject, and select ‘switch unreal engine version’…

97

I have a 4k monitor and just upgraded my project from 4.17 to 4.18. Now when I press ‘play in new editor window (pie)’ my window is all of a sudden much smaller than it was in 4.17. I’m using my mouse for touch events and those are now off as well. It looks like my input have an offset of 200 units in X and Z or something (I click on a grid of squares and a square far away from the mouse click gets the hit).

Now if I play in ‘mobile preview es2 (pie)’ things seem normal again.

Any idea why this is?

Thanks.

P.S I also noticed this is a problem when using widget reflector scaling in 4.17. I’m not using that in 4.18 nor 4.17 though as it seems buggy.

98

Is it ok? In anim blueprint all condition nodes except clean bool are marked as they have blueprint usage now.

99

So, on one hand, I see where you’re coming from, but I certainly wouldn’t want them to *stop *working on static lighting, either. 4.18 really made some important improvements that allow for even greater “photo-realism” than before when using static lighting.

This is partly because I personally get a lot more value out of static lighting than dynamic lighting, but I think this is the case for a lot of others as well. The fact is, static lighting still does a lot of things that simply can’t be done dynamically – and certainly not at the same level of quality and performance. I also there are relatively few situations in which dynamic lighting isreally necessary. Games with day/night cycles, need this functionality, but aside from that, in real life I see a lot more lights that don’t move than ones that do.

Cheio de bugs

101

Updating Engine may result in resetting some of the settings you already made in your project. Check:

  • LOD in every model (in 4.15 if i remember correctly all of my LOD that was made in the engine was reset which resulted in massive performance issues)
  • Check your In-game/Editor settings it may be possible that it switched from Epic to Cinematic.
  • If you are using Lightmaps make sure they didn’t delete them self or don’t require rebaking.

Are the 1080p intro videos supported now ?
