Unreal Engine 4.20 Preview

iOS and some android devices support occlusion queries. Just tested on iPad pro and they work in 4.20 just fine. Software path was probably made for an option to prevent popping and for Android devices that does not support those.

Can someone confirm this. I reported a bug but the response I did get was. “I am able to set the Screen Size for any of the LODs when I have Auto Compute LOD Distances = False. Moving the camera in the viewport confirms that the manually set screen size is working.” Which is basically opposite what I want to do. Problem is with auto compute distances being always the same.

Good to know! So how do we turn the software occlusion on?

Will the lens flares tool be added in the future as in CryEngine 5 or Unity ? It is another technology of rendering using textures and the possibility of using it for different light sources, and not only in one post-processing. https://www.youtube.com/watch?v=6t356IkkUmk

Automatic screen size is broken for me as well in 4.20.

Hi to everybody!!
I am completely new to the game engines universe and , my initial plan is to use its great visual dynamics resources to create movies, to add a new artistic language to my editing style,
so I am trying to find the best tools for me to achieve that, in the ideal world without having to learn to program or write codes…
That said, It would be soooo good to have a better notion of each product’s resources and limitations, but most of all, most of all to be able to have a favorites list so I can have a good notion of how this or that product would complement my needs with that other one product,

Besides all that, its good to make a list of the products you want, maybe can’t buy all at the same time… but you keep flirting with your favorites, planing…
ohh this month I’ll buy this one… and next month I’m gonna buy those other 2 that I really like

I mean, even for reference is good… So Please, pleeaasseee

Bookmark / Favorites / Wishlist However wanna name it!! Please do implement that!

Thank you very much

regards,

They said so in the live about 4.20 preview. That’s why I said it here. And they were 3 Lead Programmers, so I believed it. lol
About not moving the camera, that’s weird. If it is on Gear I guess it’s almost impossible to not move the camera. Now, if you’re talking about a erally steady camera in a standard mobile game, then you got me.

There is console switch that you have to turn first. It’s under r.Mobile. Maybe AllowSoftwareOcclusion or something. Then you also need to enable all occluders from StaticMeshEditor. You define which LOD level is used as occluder. Default is -1 which means that this mesh is not used as occluder.

I get this Error message when I wanna build the light:

**<None> === Lightmass crashed: ===Unhandled Exception: EXCEPTION_INT_DIVIDE_BY_ZERO

UPDATE!

We have just released Preview 2 for 4.20! Thank you for your continued help in testing the 4.20 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.

REMEMBER: Please report any new bugs you find by following the How To Report a Bug Guide

Thanks for all of the bugfixes! I didn’t see any mention of the auto-screen-size LOD issues some folks have been reporting in this thread. Any news on that front?

It’s reported and ticked should be open soon there. Unreal Engine Issues and Bug Tracker (UE-60353)

  • ** Mixed Reality Capture: Early Access.** The early access Mixed Reality Capture support has three components: video input, calibration, and in-game compositing. We have a list of supported webcams and HDMI capture devices that enable you to pull real world green screened video into the Engine from a variety of sources. ‘

Where can I find this list of devices. Thank you for the update.

You guys deleting all the 4/20 comments? XD

Mhm… let’s test it :wink:

Does UE 4.20 currently support Metadata from Maya? I’ve noticed support for Metadata from 3DS Max via Datasmith. Is there any way to get Metadata out from Maya assets? With the help of Python, I’m able to set_metadata and read it afterwards from any asset. But I can’t seem to read it raw from a freshly imported Maya asset.

Broken for me also.

4.20 p2:Area light is too bright after build lighting.It seems that the area light source has too much indirect light intensity

Thank you for this!

Such a shame the actual tool is buggy and needs a UI pass to make it anything remotely usable…but we live in hope for future developments.
