4.12 Released!

General Announcements
143

No more crashes, thanks for the quick fix for the quick fix :stuck_out_tongue:
One I am having is lots of my shaders are recompiling far too frequently, even with the smallest changes. I canā€™t seem to reproduce it in a new project, I expect itā€™s old baggage from my project.

144

Epic there is a game and engine breaking bug that I pointed out during release 5, and yeah I should of posted it on answerhub before posting in the threads but please look at itā€¦ Additional windows drop their FPS while in focus instead of out of focus - Platform & Builds - Unreal Engine Forums

For some reason I canā€™t install this hotfix?

ā€œIS-PQE1223ā€

This machine hasnā€™t changed since the 4.12.1 update.

any ideas?

147

I managed to upgrade my project from 4.10.4 to 4.12.0 successfully (I did have to rewrite a few parts of the varest plugin I was using and turn off the Flurry plugin temporarily). This is in the source version of 4.12.0 on Windows.

However, after a week of working in 4.12.0, Iā€™ve brought the project over to the Mac version of 4.12.0 (source as well) and while everything looks fine and building for IOS completes successfully, upon running the game on the actual device I get the message ā€œThe map specified on the commandline ā€˜/Game/Maps/LoadinglLevelā€™ could not be found. Exitingā€. Thatā€™s the very first map it has to load. All other maps are the same.

Turns out all the maps are throwing the Externally Referenced warnings. Problem is, Iā€™ve tried the renaming project folder name trick and this time it doesnā€™t work.

Iā€™ve gone into Project Settings -> Maps and Modes and reset the Editor Startup Map and Game Default Map. In addition to that, I went into Packaging and removed the whole list of maps and then re-added them in again. The editor is still complaining about external references. The build still canā€™t run on IOS. I know this project is functioning, as in the Windows Editor Source version, Iā€™ve packaged for Windows and tested it and it loads just fine. Something goes wrong bringing the project over from Windows to Mac on the same editor version.

Is this a known in 4.12? I looked at hotfix 4.12.1 and 4.12.2 but I donā€™t see anything listed that describes this. Has anyone else run into this? I donā€™t know how else to build for IOS. Iā€™ve tried packaging for IOS shipping on the source Windows version, but it seems to call Xcode to build (which naturally canā€™t work on Windows).

To further add to this, Iā€™ve tried both creating a new copy when moving the project from Windows to Mac and doing a conversion in place. Both yield the same outcome.

148

I see that problem ā€œUE-31687 Vive: Positional Latency with a Possessed Pawnā€™s Camera Componentā€ should be fixed but it persists in my project.
Do you have the same problem in 4.12.2?

149

is it me or did 4.12 break the possibility to Trace per-poly against SkeletalMeshes? I havenā€™t touched my code in months and I found this to be broken now

It seems that UE-31687 only addresses part of the, and our next 4.12 Hotfix will include the remainder: UE-31787 Vive: Positional Latency w/ Rotation. The first fix did not account for late-update rotational delta so all rotated Pawns experience an incorrect positional update.

For the externally referenced, I found a better way to fix this recently:

  • Open up your project folder and navigate to \Saved\Config
  • There should be a folder for Windows on your pc (and an equivalent on your mac)
  • Edit the Engine.ini file with a text editor

Under the [Core.System] section, make sure all of the paths containing your game content point to the correct directory, and remove any duplicates. It should look something like this:


[Core.System]
Paths=../../../Engine/Content
Paths=%GAMEDIR%Content
Paths=../../../Engine/Plugins/2D/Paper2D/Content
Paths=G:/412/OceanProject/Plugins/OceanPlugin/Content

Make sure you donā€™t delete any that are actual paths to plugins (like the last one in the list above), just make sure the path is correct.

Hope that helps! :slight_smile:

So git plugin simply wonā€™t work until 4.13? Or pull request could make it into 4.12.3?

These fixes have been merged into 4.12 and will be part of 4.12.3 (and 4.13).

Does anyone have an ETA of when the first 4.13 preview will release? Eager to try out new media framework stuff :smiley:

We are taking our time with 4.13, so the preview wonā€™t be occurring for roughly another two months. You are always welcome to check out the latest code on our Github branch though. Just be aware thereā€™s no assurances of quality or stability on .

Cheers

What are the major features planned for 4.13 ? (keeping my fingers crossed for Steamworks fixes; Gear VR stuff; new audio system with spatializer, early reflections and occlusions for Android/Gear VR) :o

We donā€™t have all that information ready to go right now, and Iā€™d like to keep this forum thread focused on the 4.12 release. Keep your eyes open for the 4.13 Preview thread in a few weeks.

Thanks

Iā€™m a bit worried my situation might be different. When I copied over my project from Windows, as per normal, I leave out the following folders:

  • Binaries
  • Build
  • Intermediate
  • Saved

My understanding is that when you go through the Unreal Engine 4 ā€œOpen a copyā€ process, it does the exact same thing.

When I first run the project through the Unreal Engine 4 Mac editor, it does not seem to generate anything but the folder WorldState under Saved. I had previously looked for the Engine.ini file too.

On Monday when I get back into the office, Iā€™ll try instead to copy over the entire Windows project folder including the folders Binaries, Build, Intermediate and Saved.

What I can see in the project folder in Windows are the following:


[Core.System]
Paths=../../../Engine/Content
Paths=%GAMEDIR%Content
Paths=../../../Engine/Plugins/2D/Paper2D/Content

I wonder if my is arising from the fact that the Mac version of the Editor is not generating this file for me.

Just to further add more information, I have tried to package my project in both the 4.12.0 and 4.12.2 source version of the editor on Mac without success. Both versions of the engine will still complain about the external references. I guess on Monday Iā€™ll experiment with the steps above. I appreciate you taking the time to respond to me :slight_smile:

Sequencer Questions:
Any way to import and use image sequences within Sequencer, I know you can export/render them outā€¦but what about importing them back in?

Can you do things like export sequencers edit decision lists, to a .psk file and import to use with blenders sequencer?

If image sequences are not supported, is there any better way to do this than to point a camera at a in game texture running cycling the frames? It sounds like one in theory could line up several camera all pointed at movie textures, and then still do basic cut dissolve editing with the Sequencer, but iā€™d like to see this become more of a real NLEā€¦while still offering all the runtime game support which is amazing. Is this the plan, do you have a roadmap?

Just found Media Framework:
.unrealengine.com/latest/INT/Engine/MediaFramework/index.html

So basically, how would I use these media files in Sequencer, can I, or will we be able to soon? Also might want to create a Sequencer section in forums, so we can post questions like this there. Thanks and great work on this!

4.12.2 Bug Roughness pls FIX problem, in 4.11 good work materialsā€¦

161

[=;545474]
is it me or did 4.12 break the possibility to Trace per-poly against SkeletalMeshes? I havenā€™t touched my code in months and I found this to be broken now
[/]

I investigated further

apparently tracing and MasterPoseComponent is broken again, and for worse this time.

Epic please look here: Traces fail on perpoly SkeletalMesh using MasterPoseComponent - Character & Animation - Epic Developer Community Forums

I could really use some help here from the Unreal developers. What file does the Engine check on Mac to determine if a map has external references? Even after copying over the Windows project folder in full and doing a conversion in place, the Mac editor refuses to recognise that the maps and their contents are within the same project folder (4.12.0 to 4.12.0 and 4.12.2 to 4.12.2 both tried).

The file on Windows, Engine.ini under Saved/Config/Windows doesnā€™t exist when opening with the Mac editor. I tried creating the folder and file Saved/Config/Mac/Engine.ini but to no avail. Something, anything to point me in the right direction.

Hello,

I switched my project from UE4.11.2 to UE4.12.2 and I am facing some issues with Child Actor Components. Details here:
https://answers.unrealengine.com/questions/435161/issue-with-bp-child-component-actors-in-4122.html

Mesh instancing is involved, I donā€™t know if it is related to the.

Please let me know if a fix can be included in 4.12.3.

Thanks a lot

Julien
