maybe its me? but latest 4.5 preview source doesn’t run (no errors during compile). Think there may be an issue with binaries.
Edit: New binaries seem to have fixed it 
It is running on my system 
(x64 that is)
The latest preview build has been updated to changelist 2337679.
The latest preview build has been updated to changelist 2340836.
latest preview build is not compiling for me, offending lines:
#include “steam/steam_api.h”
#include “steam/steamvr.h”
in SteamVRPrivatePCH.h
I can not find these headers.
okey figured out whats the problem.
In 3rd_party folder, there is Steamworks which should only contain Steamworks.build.cs if you dont want to build with Steamworks support. So delete the others file (a folder which contain compiled sdk, called Steamv130). If you delete it, then the UE4 builder will set a boolean to false indicating you dont want to use steam and will not compile the offending cpps.
These files are included in Required_2of3.zip and I think they should be deleted …
Ah, apologies. We are allowed to distribute the Steamworks SDK with the engine now, but the headers are missing from Git. I will add them in.
I have a feeling a preview build is coming soon 
I really hope so. I am really looking forward to having a go at Niagara. Genuinely excited. Can we please get a master preview please?
Is the 4.6 branch up to date with its dependencies?
If there is a possibility of getting a build with the previously mentioned c++ changed (new contructors and removed Tptrs), then I will be very happy.
Cheers

The latest preview build tag has had the C++ changes for more than 10 days 
Oh yeah. Nice. Shame that Niagara doesn’t seem to be fully finished yet. I can create a Niagara Actor but can’t seem to create a Niagara Effect. Must still be in the works.
EDIT: Just seen the post on how to enable the editor and be able to create an effect. Cool.
EDIT 2: I can create a Niagara Actor, an Effect and a script. I can apply the Effect in the Niagara Component in the Actor but when I create an Emmiter in the Editor, there is a crash when it gets to UMaterialInterface::GetRelevance(). Having a little debug but I have no idea how it’s meant to work so not expecting to get far.
Any we get a new preview snapshot, or perhaps a 4.6 preview?
Cheers!
4.6 preview is here
https://github.com/EpicGames/UnrealEngine/releases/tag/latest-preview
Thanks, I am well aware of this preview tag.
I was asking for a newer snapshot, perhaps a tag on the fairly new 4.6 branch. This would help me test my git plugin before the 4.6 release.
is this what you’re asking for? (sorry if i misunderstood your question) https://github.com/EpicGames/UnrealEngine/tree/4.6
I think he is asking for a more “stable” release of this branch. Which usually gets a tag (ie. latest preview build)
Yes, the point is that Epic has to release the binary dependencies associated with a specific git revision.
For any other git commit you are not guaranteed to be able to build our to launch the Editor.
oh! i see. Yeah you’re right, right now the latest ‘tagged’ version is from 15 days ago (is 4.6 that far away? i read somewhere 4-6 weeks yet). Sorry for my wrong link.
I’ve been able to compile 4.6 from the branch using the new got dependencies script and disabling the oculus plugin. Also there was one line I had to change in the build script to get it to pass though.
Oh and only debug Editor would compile. there were errors building UE4commandlinetool for arm architecture.
We’re still ironing out the last few bugs with the new scripts that have been submitted, though I’m impressed that so many people are trying them already.
The new ‘promoted’ branch will contain our ‘latest-preview’ builds from now on, and it’ll be updated automatically as soon as our QA team sign off on stable builds. Apologies for the delay in rolling this out; we’re almost there.
