Hi,

Sorry if is a dumb question but I did not know where else to ask.
I made a small demo using the fleX unreal engine version. I wanted to show what I made to a friend but when I tried packaging the game I got the error:


 MainFrameActions: Packaging (Windows (64-bit)): ErrorReporter.Error: ERROR: AutomationTool error: No files found to deploy for I:\UE4\flexDevelopment\UnrealEngine-FleX\Engine\Binaries\Win64 with wildcard UE4Game-Win64-Shipping.exe and exclusions

Is there fleX unreal engine not ready for packaging yet or is the error on my side?

Thanks for listening :slight_smile:

I havenā€™t tried it, so I wouldnā€™t be surprised if thereā€™s some kind of bug. Iā€™m not sure. Sorry, wish I could be of more help .

Looks like something wrong with your paths. No files found to deploy for I:\UE4\flexDevelopment\ . Are you building a project from there or your desktop?

hi im trying to run the flex demo under linux and wasnt able to understand whats going on completely, i wish i could provide more info, could you please help me to find a way to fix ?
the thing is i cant debug it properly as i dont have the source for flex.cu and i dont know exactly how it works under the hood, like where does that info come from? it seems it has hardcoded dependencies on libcudart-5.5 and Iā€™am using version 7.0 already, any help is greatly appreciated!

Will all of these gameworks features be for nvidia cards only for a long time? Iā€™m deciding on getting either a titan X or 390X,
I think the 390x will be same performance as titanx but like half the cost?
Unless all these gameworks features wont work on amd cards until like 6 months or 1 year then I will just go with nvidia

Hi,

Iā€™m afraid we havenā€™t tested the FleX-UE4 integration broadly under Linux yet. I know that FleX itself will run on Linux, but as you noted it appears we are using and older version of CUDA. Is there no way to try it with CUDA-5.5?

805

The schedule for support (instead of CUDA) varies with the , and is determined by whether we are able to achieve the desired results with. Already VXGI, HBAO+ support, but FleX and WaveWorks are CUDA. Iā€™m afraid I donā€™t have exact dates for availability of on those features yet.

806

I build with scripts and one of them builds shipping targets, and they do work, though FleX needs a patch: /NvPhysX/UnrealEngine/issues/14

Apply that and build UE4Game Shipping Win64.

807

Just to be sure: are the branches updated to 4.7.2 or still with 4.6.1?

808

UE4 has really a problem with reflections: https://vimeo/122314583

SSR arenā€™t enough to render all reflections caused by indirect light sources and not just screen-space ones. I really hope VXGI adds reflections caused by litgh bounces so we can get real reflections like in real life.

809

I also downloaded the branch version of UE4 with nVIDIAā€™s VXGI.
It looks .

is why you donā€™t rely solely on SSR, you use SSR together with reflection captures. Most ArchViz projects Iā€™ve seen so far use static lighting and had decent reflections, at least from what I can tell.
VXGI will have to offer a replacement for the reflection captures as they only work with Lightmaps, but donā€™t expect anything great as realtime reflections outside screen-space would kill most machines (as far as my knowledge goes).
I think someone mentioned that we would need at least two bounces to get proper reflections or something like that. But if anyone wants to correct Iā€™m eager to learn more! :slight_smile:

Greetings,

811

Still 4.6.1, sorry for the delay.

812

Yes it was me talking to who confirmed that. :slight_smile:

No problem. Looking forward to see all branches merged with 4.7.3 (just released now, and there will be 4.7.4 fix soon).

813

Ahh, Iā€™m sorry. That means you already know more than me, I thought someone else mentioned that ^^
I do hope that VXGI gets multiple bounces soon, but I guess we will have to wait. For now I just want to have 4.7 :slight_smile:

Greetings,

814

I think they better switch to 4.7 after hairworks :stuck_out_tongue: 4.7 all in one =D

815

i wasnt able to run it under linux yet, which library gets its hardcoded dependency from cuda-5.5? cant you distribute its sources so we can build and debug ourselves?

816

Ive seen the WaveWorks in action an it looks truly amazing :slight_smile: Now I hope its not long until they get FlameWorks.

Hi I saw Tomā€™s Titan X demos today at GTC. They showed off the Unreal Engine 4 Kite demo and 2 Flex demos(balloon and red dress). Do you know if you can share these demos out to us or are they strictly private? is a link to the demos I am talking about ://www.twitch.tv/pcper/b/638116071?t=11m50s
