0lento Thanks for the response. I went back and tried to do several more builds none of them worked. Eventually I downloaded VS2015 and it worked right off the bat. Must be something in 2017 it doesnt like.

This is bit weird, I did a clean build with VS2017 as well and didn't encounter any issues.

I can't include substance on my fork as I'm not allowed to distribute source code from marketplace (substance plugin). You can get the plugin youself from the marketplace and place it into your own projects Plugins folder. Then generate your game's project files again and UE4 will compile substance plugin along with your project.

Worth mentioning that you need to have c++ project for this, so if your project is currently blueprint only, you need to do is place the substance plugin as I mentioned and then generate any dummy c++ file with UE4 editor to get the c++ solution file.

thank you
how to do this please any video

Has anyone heard about the Unity release date yet? I saw NVidia's stand up at GDC 2018. They showcased the Unity plugin they've made, and said it would be released after the event. That was back in March. Has anyone heard anything since? Thanks!

I imagine you mean FleX for Unity now. I've been looking for this info myself as well but haven't found any mention about it since GDC. This forum isn't best place to ask about it tho as this isn't relevant to Unreal. You can expect the Unity FleX-plugin to arrive here once they've done with it: https://assetstore.unity.com/publishers/13586 (or https://developer.nvidia.com/flex)

Would be pretty pointless for me to make a video about this as I don't even install Launcher or Binary Engines into default folders, me making video with setup like this would just cause more confusion.

Just figure out where the your stock UE4 is installed and navigate to it's <Engine Version>/Plugins/Marketplace folder, this is where substance plugin gets installed from Epic Launcher. You probably could just place this plugin into similar place on custom/Gameworks engine folder before you generate project files but I haven't tested this. Otherwise you can just place the plugin on <your project>/Plugins -folder and then generate the project files like mentioned before.

Nigel_TacHaz they just released 1.0 beta: https://assetstore.unity.com/package...-0-beta-121316

edit-> oops, that's only sample scenes, actual plugin is still missing (can't take long now tho)
edit 2-> actual plugin is now live as well: https://assetstore.unity.com/package...-0-beta-120425

Hi!

So I tried to combine both FleX and Blast together in UE4.19.2. Code wise merges fine and builds.

What's the best way to get a FlexActor (softbody) reacting to a BlastMeshActor? Right now it just passes through, and if I change the collision settings on the FlexActor to collide, it just fractures and destroys my BlastMeshActor?

If your Flex actor is interacting with Blast actors, then it's working. The thing with Blast is, the parameters are quite sensitive. It's been a while since I tinkered, but a previous project I worked on require A LOT of subtle tweaks here and there to get things breaking as intended. And it's different for each "type" of object, for example a thin stone slab versus a thick concrete wall.

I intended to do an article or tutorial of sorts covering these things, but I have yet to find all the "magic" numbers for parameters and further... Well, Blast objects are so variable in their setup, it's hard to say to someone "check this box and enter this number in that field". If someone else has some proven numbers, I'd love to see! Otherwise, it's a process of tweaking, testing, tweaking, testing...

0lento I get this error when im trying to package my project:

UATHelper: Packaging (Windows (64-bit)):   ERROR: UBT ERROR: Failed to produce item: D:\Software\UnrealEngine-4.19-GameWorks\Engine\Plugins\Media\WmfMedia\Binaries\Win64\UE4-WmfMedia-Win64-Shipping.lib

Any idea what this might be and how to fix it?

I got had the exact same error. I ended up re-installing VS 2017 and recompiling from the ground up and it cleared it up.

That error doesn't tell much of why it failed to compile, the real error is most likely listed well before that line. Always seek for the first compile error if having issues. I've compiled this myself with both VS2015 and VS2017 without issues but I'm not sure if I have latest updates for VS2017 atm.

0lento Hey 0lento, quick question, I just want an 4.19 engine version with flex, I do not need the other nvidia techs... I already downloaded it and compiled it... seems to work. My question is that you mentioned in this thread that you have to make some changes to flex to make it package able... are these complicated, could you give me a rundown? or you think the flex version on the nvidia repository as stand alone is good to go? Thank you !

This is my first Error, after that I get more errors:

catalejo well, you can try the packaging first, if it works on your setup, it's fine. I do have a PR for some IWYU fixes here https://github.com/NvPhysX/UnrealEngine/pull/523, or alternatively, you can grab the branch for that PR while it's live (I'll delete it once nvidia fixes this): https://github.com/0lento/UnrealEngi...PR-FleX-4.19.2 (this contains exactly same commits as the nvidias FleX-4.19-2 atm plus those few fixes).

VRWijnen I'm afraid that's not really helping much, can you post the full build log somewhere (pastebin etc) and share the link to me so I could take a better look?
