where to find the new render movie manager ?

[Edit as of 4/7] finally sifted deeper through the commit history and the patch for the linked issue in the original post was applied all the way back in preview one, simply converting a float to a double in a number of files to buy some time however my different needs/project setup continues reproduce the error with the patch applied as discussed below (concert media servers can have some real marathon sessions in real world use too) and a more fundamental fix is needed in the long term. In the short term the workaround is simply to restart things every so often or make the usage of a second machine redundant by throwing money at the problem and buying a DeckLink card.

[Edit as of 3/13] Leaving a listen server up and running for a day and then opening a fresh client on a new machine fails to connect and thus reproduces the issue once more on 4.25 preview 2. The issue is also reproducible bidirectionally in this circumstance regardless of which machine attempts connection as a client while both default to being a listen server. This seems fairly conclusive that this is in fact the same NetDriver issue that has been fixed already and is pending release. Relaunching causes things to work properly again.

[Edit as of 3/12] Opening things up fresh after leaving everything closed for a day seems to connect up fine in all Preview 2 in various ways of launching it. I think it’s relatively safe to say this is probably related to the NetDriver time issue, for which the tracker page is linked in the explanation of below. While I do have a tendency to leave things open overnight at times, my original issues were strangely happening on PIE sessions shortly after fresh editor launches having resynced between different git branches, and likewise, any standalone game session launches which also initially replicated the issue should also have been fresh? The issue seems related to the NetDriver time issue however I’m still a little miffed based on my understanding of that issue.

[original post]
I tend to lurk and don’t post often but I was doing some testing on migrating a copy of my long in development VJ software framework from 4.24 to 4.25 preview 2 and despite reliance on a number of plugins, everything’s been working fine… up until testing the net-code bit which gets quite angry although works fine in the current 4.24 release. I’ve wanted to post about this project for a while but have had some legitimate reasons not to. I plan to elaborate on it soon. In short tho, calling the console command to open an IP to become a client bounces back and remains a second listen server, as does when automatically running two PIE windows with one as a listen server, and another that’s supposed to auto-connect as a client, but it’s still just two listen servers. Pulled my hair out for a while double checking firewall rules when I eventually got an engine crash out of it so it may be something going on with the preview since I’ve never seen this up until now.

Running with Windows 10 1803 on an i7-4770 with a GTX 1650. Running slightly different but largely similar hardware and standardized OS versions and driver versions (Nvidia 440.97) across all three dev machines and reproduced the issue centrally with two instances on the primary machine and (attempting to) connect a client on the secondary machine to a listen server on the primary having repeatedly verified firewall rules on each for both UE4Editor and UE4Game for each engine version installed.

I eventually ended up with the following crash page and error log snippet related to the crash starting from entering the console command to connect. Let me know if there’s a more preferred method of formatting this info for the forums as I didn’t see anything listed so I can stick it in a paste bin or something for anything prior to the point of a filing a formal bug report. This problem may relate to this issue but considering I haven’t had any problems of this nature in prior versions ranging from 4.18 up through 4.24, I feel like it may be different but possibly related. Curious if anyone has thoughts on this as to whether it’s the same issue or indeed a unique one and if I should file a formal bug report.

This post is kinda too long already, but I should add since I don't know where else to put it that I for some reason can't update my bio if I'm gonna quit lurking because it tells me I've entered an invalid birthday when there's no birthday field to edit on any of the settings pages. I remember there was a forum migration sometime back so I have to assume this is a remnant from that since my forum account is technically from 2015: https://photos.app.goo.gl/pgNtrD91XVhhkPhTA

Just downloaded 4.25 p2 from github. Has anyone been able to get a clean compile? If so is Chaos there? ? There is no Chaos Destruction Demo for 4.25 p2.

Hello. I’m trying to setup for Android build and followed the blog post https://www.unrealengine.com/en-US/t…al-engine-4-25 but at point 3 I need to install Android NDK r21 but Android folder is missing from UE4 folder. I’ve reinstalled the 4.25P2 version and I still can’t find it.
Edit: Also I can’t accept Android SDK License. The file is missing

What did you use for Chaos?

I just did the compile with the 4.25P2 source. Here is the error.

Epic have you tried??? I did not use Chaos Destruction Demo for 4.23 or 4.24.

anyway, I decide in android studio update and download SDK, NDK, version 16 to 21, also separate download NDK r14b and r18b.
unreal engine 4.25 can’t even configure and accept the license.

I like the changes in the control rig, except you can no longer pass in or return variables?

I see the variable options to get and set but before you could choose them to be exposed as input or output and I don’t see those options. Without input or output it seems like the control rig has pretty limited value… I thought the big value was to abstract away complicated animation calculations, which would need the input variables to drive it?

itsAcren · March 16, 2020, 1:43am

Real shame to see that UE-66800 target fix was pushed back yet again to 4.26, which has for a while already been the only thing preventing me from using the material layering system.

That will mark at least 7 engine versions since the initial implementation. (Noting of course that development was fully paused for a while)

Hope it can be addressed soon!
