NVIDIA GameWorks Integration

[Number47]

True, but shader compile time is quite a bit slower, and somehow all my materials have been marked with “VXGI”, and I don’t want to go through them all and uncheck.

@Daniel.Wenograd;427864

Just don’t enable it in post-process. Not really any harm having it there if you don’t use it.

[Zero-Night]

Uncheck it before hitting the compile button.

The only other way is just to build a merged branch yourself, which while it isn’t too terrible to do so, it can introduce back a lot of the issues that GalaxyMan fixed. There may be an option somewhere to not make VXGI enabled the default option, it didn’t used to be until 4.9 and past it, but the easiest solution is just to turn off VXGI for the materials you need to edit from this point forward, and just eat the longer compile time for the rest of them when the project first loads.

I wonder, Does PhysX Flex supports AMD Cards?

I think FLEX is currently (dunno if that will change) Nvidia only as far as I know.

Hey guys,

How can I import a .OBJ into a scene on FLEX CUDA install?

For example, I have a .OBJ rope file, that I would like to replace into the rope scene and have it simulated.

thanks!

[Gandosh]

Alright. I got problems with Visual Studio 2015… I can’t even build my engine xD
Galaxyman what version did you used? to build your latest merge? I tried to install VS2015 but its failed. It says Teamexplorer failed to install. Now i cant even use 2013…

[Number47]

Thanks, I suspected, there was no “easy” way out.

Thought I’d share my character using HairWorks.

This is what i got ticking the particle mode:

Did you ever find a solution to this? Not sure if it’s the exact same error for me, but enabling particle mode crashes the editor for me as well. Unsure how to go about testing Flex at the moment. Also noticed that some of my editor options are missing compared to GalaxyMan’s screenshot of the component.

[ianoreo]

Has anyone had any luck integrating the community OceanProject? Tried the 4.9 branch and then just a simple project folder re-compile but it failed. Seems to think it is the wrong version…

Excellent stuff though GalaxyMan! Thanks for the work you’re putting into this.

[DanielGarcia]

it is possible to have a guide on how to integrate hairworks in other UE4 versions?, for example what files or assets do we need to include in our UE source .Net project?.
I am already working with UE 4.8 and I dont want to migrate all my code and assets to Nvidia’s UE versions. :).
By the way, thanks a lot for making hairworks working with UE. I have been waiting for this long time

[Xu_Nie]

The new integration is still based on UE4.7.5. The next coming release should be based on 4.10. If you don’t want to do the upgrading by yourself, I think you have to wait for that.

@GalaxyMan2015;415727

I have exposed FlexComponent to blueprints in one of my prior commits, so my branch at this point should allow that (Not much is accessible from it, such as container instance properties, etc. am working on that). And yes I have had issues getting location data from flex actors. I did have a workaround (using custom location handling) but it broke rigid bodies, so will try again at some point.

Hi GalaxyMan,

Was wondering about similar issues too…is it actually possible to get Flex particle position/velocity, as well as collision position/normal/speed? (basically all the metrics exposed by the Flex API itself)

Cheers
Melvin.

hi guys.
i am using Galexyman2015 branch v4.9 . Thank you for you hard works.
I have tow questions about flex:

1. Is there any tutorial on how to using flex? pdf or sample or video?
2. I am using apex and maya for creating cloth but unfortunately i got that exported cloth not interacted with world i want to know that flex cloth is same as apex cloth or it can interact or collide with world?

Thanks.
Sajjad shirzadi.

Hi.

1)Not sure if it is in galaxymans branch, but in official flex branch in UnrealEngine/FlexProject/Documentation/ is a documentation.

[Dogsofknowledge]

Newbie question, why do bouyant objects not change rotation on the WaveWorks ocean? All objects can move around, but they don’t seem to rotate at all on the water. http://imgur.com/4nqlQwj In this demo the ship rotates, am I doing something wrong?

Thanks!

https://youtube.com/watch?v=iilqtDkeIBE

EDIT: Another question, how can I set Waveworks to only interact with certain static meshes instead of everything? When I set any static meshes to Static, the game runs slower and slower until eventually it crashes, and when I set the static meshes to Movable, then they float along with the waves no matter what I try.

[starfish7985]

Is there any way to get rid of the visual representation of an emissive object in VXGI without loosing them as lights?

I am using some emissive planes to light my scene, but I don’t want to see them.
Something like “primary visibility off” in Maya. So they still emit light, but cannot be seen in the users camera?

Hello everyone! I’d like to mention that we just updated HairWorks on GitHub. This is still for UE4 4.7.5 and is compatible with an updated set of HairWorks 1.1.1 tools on Devzone. This release has plenty of bug fixes, functional improvements, and has an improved workflow. We do not have a 4.10 version ready just yet. I’ll post it here as soon as it is.

I guess by the time you have it Epic will release 4.11 so maybe you want to be a head of the game and work on 4.11 instead
(Just a thought)
