Unreal Engine 4.21 Preview

[phoboz]

After the update to **preview2 **I am unable to package my plugin. I can add it as code-based plugin to code-based projects and they compile, run and deploy just fine, but I cannot generate the plugin binaries on their own.

During packaging I get the following error:

I checked the path it points to, and it ends at ‘XXX\PointCloudPlugin\HostProject\Plugins\PointCloudPlugin\Intermediate\Build\Win64\UE4’ - there is no ‘Development’ folder.

In addition, this corrupts my whole UE4.21 installation, so that I have to run verify on it before I can run the engine again (any projects, even non-related to the plugin). As a matter of fact I can’t even get to the engine project wizard at this point. Get this crash report instead:

• **Oculus Avatars. **The Oculus Avatar SDK includes an Unreal package to assist developers in implementing first-person hand presence for the Rift and Touch

Hi @Shadow.Storm is it possible to have some info about this package.
Thanks.

[kurylo3d]

@DamirH

Yes of course, that is my point, it is still early.

So because you dont want to use RTX and raytracing… no one should? Well… the new battlefield game and the new tombraider games disagree with you.

[astonish]

Happy to see the move over to the new SteamVR input system. Last I checked in on the dev-vr branch it was just the basics being wired up. With Knuckles EV3 I’m very interested in the skeletal model the input API provides. Any idea of the timeline for getting this particular piece of data out of the input system in an unreal native data type? (even if it isn’t a solution that is fully wired up to the default hand model). Just trying to decide if that will come in the 4.21 release window or whether I should start our own implementation?

@kurylo3d

So because you dont want to use RTX and raytracing.. no one should? Well.. the new battlefield game and the new tombraider games disagree with you.

None of those games use RTX properly it’s just half-implemented, post-launch, only for early adopters of the hardware. But you don’t want to hear that nor what I am actually saying, which is: Real Time Ray Tracing is not even remotely close to being universally accepted like programmable shaders are today. An EXTREMELY SMALL subset of PC only devices having access to it means that its development should NOT be a priority because statistically speaking it makes no sense whatsoever. The main driving force behind the technology being nVidia and Microsoft will only make general adoption of it that much more slower.

Nowhere did I ever say that I don’t want to use it. But in the real world more games release on consoles, including the Switch and no one except high-end AAA studios can afford implementing a fledgling piece of tech just for <1% of their consumer base who have a RTX card. Us mortals have to develop for the lowest common denominator.

Edit: I can’t seem to find the source of the info that I’ve read regarding the RTX implementation in Tomb Raider but apparently it only uses a subset of the features and not full-fledged ray-tracing, whatever that entails.

Most of the games will use hybrid raytracing. First they rasterize gbuffer and then ray trace for effects where it make most sense. Like for GI, ambient occlusion, reflections, soft shadows. This way you don’t need to rework whole engine and you can enable/disable effects depending on performance and needs. Tracing also primary rays would be big CPU optimization(just single draw call) but depending on GPU it might be tad slower.

SVirtualJoystick doesn’t follow DPI Curve.
It has it’s own scaling approach.

It’s a bug that I raised on the previous version already: Case # 00057452:

Thanks,

[anon53618112]

Really sad to see UE-62291 get pushed to 4.22. Would have loved to be able to use all nifty Switch optimizations from 4.20+ before we release, but sadly it makes our game unplayable.

The reason AAA developers will put in RT features in their games is because they are technology enthusiasts and it becomes “free” advertising. Nvidia will promote the game, benchmarks will feature the game, gaming new sites will pay extra attention to the game. There’s no reason indie devs couldn’t do the same thing.

Even swapping SSAO for RTAO is a perfectly acceptable, “fully implemented” option for developers. And has a huge effect on visual quality. Hopefully UE4 will make implementing it very easy.

Usually graphics programmers just like to push visuals using all available tools. Marketing can then spin it anyway they want.

Hello ,

The bug report that was entered for your first issue was marked as Won’t Fix due to a lack of activity on the report. Can you please enter a bug submission for this issue using our Bug Submission form and include a link to that Answerhub post in the description, along with any other information you can provide?

As for the second issue, please report that one through the form as well, preferably with a reproduction project if possible.

Please for the love of God fix the landscape blending to allow blending of physical materials, this was supposed to be fixed in 4.14, but was removed, it’s really annoying to apply sound that’s only available when you hand paint the ground instead of applying with auto blend.

Hello ,

This was not reported as a bug but as a Feature Request. Although we do not make feature requests public, I’ve checked up on the status of this and it is still backlogged at this time, meaning that it has not yet been implemented. Unfortunately I have no estimate on when it may be included.

@aussieburger

Many thanks for this! Android cook times for my projects are much faster now

One thing I’ve noticed with 4.21 P1 however I can’t see how to do print screen stat commands anymore in VR. 4.20 had a “use debug canvas” checkbox under VR rendering settings which does not exist in 4.21 anymore. Makes sense, since this should have been on for VR projects by default, however testing with a GearVR / GO I don’t see any output anymore.

Can anyone else confirm this? Is there another way it’s meant to be shown now??

Hello Aussieburger,

I do see a report in our system for some fixes added to 4.21 that is related to this feature but I see no evidence of this problem being reported. Can you please report this using the Bug Submission Form so that we can take a look?

Does 4.21 fix the issue with broken Vehicle Replication?
Unreal Engine Issues and Bug Tracker (UE-62345)

Hello KAEPS133, that issue is still unresolved at this time. When it is marked as Fixed on that page, you can likely expect it to be included in the release that happens after that.

After the update to **preview2 **I am unable to package my plugin. I can add it as code-based plugin to code-based projects and they compile, run and deploy just fine, but I cannot generate the plugin binaries on their own.

Hello Phoboz,

I believe we’ve already received your bug submission by this point and have that all worked out. The fix for this has already been entered and should be available in the next Preview release. Thank you for reporting this!

My project won’t open at all in 4.21 p3, was able to open it in p1.

Hello BendikSlyngstad,

I would suggest making a post on the Answerhub if you believe that this may an issue with your project. If you believe that this is a bug with the editor however and you can provide a reproduction case, please submit a bug report using our Bug Submission form and provide as much information as possible so that we may investigate.
