Unreal Engine 4.13 Preview

Forward rendering in 4.13 is super early, only the first checkin of many really, and not ready for general use. That’s why it’s not being announced in this release. I expect it will be ready for use in 4.14.

The only things working in 4.13 are the actual forward rendering of multiple lights, with dynamic shadows from stationary lights on opaque. No MSAA (which is the whole point of forward), no significant performance gains, no blended reflection captures, no shadow receiving on translucency or even support for translucency lighting modes.

Capsule shadows are the only supported dynamic AO method. SSAO could be made to work but it’s super low priority due to SSAO generally being terrible in VR (mismatch between eyes causes strain), which is what the forward renderer is targeted at.

Thanks for the answer!

I absolutely need SSAO in my VR project, and I never noticed any problems with that, I have it set to lowest quality but TAA works really well with blurring it so much that it still looks great. I’ve never noticed any difference between the two eyes and SSAO. I really want to use the forward renderer since I need as much performance as possible in VR, but I won’t be able to use it if it won’t support SSAO. I know I’d have to switch to the gaussian blur when using MSAA instead of TAA, but that’s not much of a problem I think.

Are you sure there’s any noticeable problem in VR with SSAO? I used it for months now and I’m quite sure I would have noticed if it wouldn’t look right. I use SSAO mostly to replace dynamic shadows since they are so expensive, and it’s great at faking those shadows with the right settings.

Also still very disappointed to see the context menu search issue on macOS doesn’t appear to be working still. (UE-29885). Unreal Editor went through all of 4.12, including the previews with this issue and looks like still no fix for a major usability problem on macOS.

THIS! A THOUSAND TIMES, THIS!

Everyone go vote for UE-29885 and UE-29024!!! Mac and Linux lost the ability for the right-click-context menu in blueprints to auto-focus when 4.11 was introduced. And Epic doesn’t seem to care. This affects me constantly.

VOTE!!!

Actually i would love to know a bit more about Improvements to Instanced Stereo Rendering

In the livestream today they said that setting improves VR rendering performance by up to ~10%

Osman mentioned Mesh Decals on Twitter, do you have more details on these? Cheers!

I was just going to ask the same thing… Any info about Mesh Decals?

How does the media framework function? I create a source, create a media player, texture for the material, in blueprint open the appropriate source for that media player, play it. I get video but no audio from my video file. Do I have to import the audio as a wav or something still? I hear the audio playing within the media player preview, just not in the game.

Is media playback or video playback working on the mac yet or not? gmpreussner said he was working on it last week?

no AR support， like google’s tango and microsoft holoens??
I really want that, please…

Thanks for your greate work!
I see the mobile update:Custom Post-Process material support

How can I enable post-process material effects for mobile?Thanks! [MENTION=9]Stephen Ellis[/MENTION]

It’s a same as on other platforms:

Post Process Materials

Restrictions are: project needs MobileHDR enabled and only PostProcessInput0 is supported.

So when do we get the live stream recap on youtube because most of us can’t actually watch those things. Mainly because twitch is broken on mobile but hey not your issue.

https://docs.unrealengine.com/latest/INT/Engine/Rendering/PostProcessEffects/PostProcessMaterials/

Thanks,maybe the outline effect still cannot be turned on mobile right?Since the material requires the scenetexture:CustomDepth node which is still not supported on mobile.So is there an alternative to show that outline effect?Thanks!

Seems in C++ the Procedural Mesh Component is broken, if you try to add it to an existing class or to create a new Procedural Mesh Component class (both via a C++ or Blueprint project) it fail on compile do a ‘FKConvexElem’ not defined class, can someone confirm?

EDIT:

Meanwhile i reported as bug on answerhub here.

[order66]

Was there anything in the stream related to mesh decals?

Was there anything in the stream related to mesh decals?

No but it was mentioned in the Twitch stream thread by Mike Fricker (he forgot to mention it in the stream):

@DarkVeil;576358

However no worries – there are quite a few other cool 4.13 features that I didn’t even highlight on the stream, such as Mesh Decals! Stay tuned for the full release notes in a few weeks.

At least from what intuitively expected to happen it seems like the alpha is inverted on the new Draw Material to Render Target blueprint node. I have submitted a bug report with steps for replicating here:

Draw Material To Render Target Node has Inverted Alpha

You can do that know fairly easily, just use level streaming / portals.

VR Template, yay!

Elaborate? Like, where is the portals of which you speak of?

[sbnewsom]

Regarding Media Framework, is the desynced audio and requirement to use super short videos still there? If so, these are two things everyone should be focused on. I’ve been waiting so long to implement my cinematic cutscenes as it is. They are neither low quality nor short.

[Arquimia]

Does the VR template allow you to package the project to see it directly with the HTC vive?

The 4.13 Features Twitch stream has been added to the first post in this thread. Or, watch it here: https://www.youtube.com/watch?v=fiIx9CXtr0M

Thanks! Okay my post is to short where do I go to learn more about the tessellation improvements?
