Unreal Engine 4.21 Preview

[Kalle_H]

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.

This bug has reappered. https://answers.unrealengine.com/que...-using-pl.html

Exposure seems to be broken in multiple ways. Scale has changed oddly on pc. On mobile exposure don't do anything anymore. What has changed and how exposure compensation should used now?

Hello Kalle,

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 Frostydowns,

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.

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?

Hello RoboPoco7, if you would like to report this issue, please use our Bug Submission form and we will be happy to look into the problem. Please provide as much detail as possible for reproducing the issue when doing so.

Does 4.21 fix the issue with broken Vehicle Replication?

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.

I am unable to reproduce it in a new project as I have no idea whats causing the issue. Will work on isolating it, but there is definitely some change in p3 that in relation to some aspect of my project causes the crash. it works when opening the project with an empty level as default, but once i load any of the levels actually related to the project, it crashes. Will post a bug report if I'm eventually able to isolate and reproduce the issue in a separate project.

Wow, you're really looking ahead! 4.21 isn't even released yet.

i have no intereest in anything in 4.21... im enthusiastic about rtx raytraced lightmaps for speed and fun doing environment artwork. 4.21 is a very very boring update... I just want that 1 feature... raytracing realtime lightmapping...

I appreciate the info though

Late q1 for 2019... that sucks... I bought this rtx card for nothing :/

[Stephen Ellis]

Well, early versions of the 4.22 code will be available on GitHub in the Master and Dev-branches. You can always compile the engine from the source code and follow along with development. Just be aware there will be bugs and incomplete features, so don't rely on it for your own professional projects at that stage.

kind of an amateur with all that. Im teaching myself game programming with udemy.. but im an artist by trade... which is why i was so excited about rtx features in the engine.

Do you have any links to tutorials on how i would do this?
