Unreal Engine 4.12 Preview

[John Alcatraz]

[MENTION=9]Stephen Ellis[/MENTION] can you provide any information as to whether this roadmap feature might be in 4.12? https://trello.com/c/ZudPpWUr

May most likely means "added to master branch in May", so it won't be in 4.12 I think.

Probably 4.13 then, thanks for the insight John

Planar reflections are a great addition, and they look perfect in non-VR.

In VR, or specifically the Vive, there's a lag in the reflection, like it's trailing behind the reflected objects. Does this have something to do with late-update / low latency magic that the HMD position uses? Should I create a bug report on Answerhub about this, or is it a known limitation.

Planar reflections haven't been made to work with VR yet. It's unlikely that you'd be able to afford them anyway in VR, so it's kindof low priority, but still something we'd like to support.

That's a shame. As for performance, they only add 0.78ms to my (fully dynamically lit) test scene, which in my opinion is very okay for something that looks so good. This feature would naturally be amazing for VR arch-vis too.

Is getting planar reflections VR compatible on the to-do list for the first release of 4.12 or is it even lower priority than that?

[TheJamsh]

The problem is with VR you probably have to render them twice, once for each eye. Could maybe do them at half-res or something to offset the cost but it's still going to be pricey. Might end up sticking out like a sore thumb

UPDATE!

We have just released Preview 5 for 4.12! Please view the Known Issues List on page 1 of this thread for the updated list of known issues.

Thank you for your continued help in testing the 4.12 build before its official release. As a reminder, the Preview builds are for testing only, and should not be used for the active development of your project.

This is expected to be the final Preview for 4.12 before its official release.

Important Known Issue

• Google VR (Daydream) doesn't work in the Launcher release, but is functional via Github (UE-31186)

You don't even know, how UE-30570 and UE-30575 Misspellings, has been throwing me off! Whew! Finally!

This bug has caused large amounts of pain and agony...in fact, I would rather be dipped head first in a vat of hot chicken fat than having UE-30570 and UE-30575 not fixed!

Will UE-30842 be fixed in 4.12? This is a major showstopper for our Vive/Oculus Project so I would be helpful to know any timing details on this? Much appreciated!

This issue is currently scheduled for the 4.13 release.

i cant find the array pin disconnection bugfix >:c
Its preview 5 already! We clearly see our bugfix in the masterbuild! How can this be a problem? Did it broke again?

[Strelok_84]

Sorry if this is a silly question, but did you guys revert to the old link gun effect in the latest build ? I really liked the new effect introduced in the first 4.12 build. Is there any way to get it back ?

Thanks !

P.S. DM-Tuba is fantastic .

Dear Epic,

Please look at UE-30242. Its a show stopper for some of us.
I cannot upgrade at all until this is addressed.

Thank you.
