Unreal Engine 4.20 Released!

[Shaun Kime]

Ok, I am crazy or Niagara makes some basic stuff super time consuming? To create a simple particle with 3 emitter you need:

• Create a Niagara System
• Create 3 Niagara Emitters
• Add the 3 Niagara Emitters inside the Niagara System

And if I need to add 1 more Emitter I need create another emitter outside the Niagara System and Add it to the the System.

Add a way to create Emitter inside the Niagara System that go inside the Niagara System folder. Them you create a Niagara System and add 3 emitters inside the system.

It's time consuming now because the infrastructure isn't yet in place. Long term vision, we have a body of emitters that are 75% of the way towards what you want. You can just pull them in and tweak the last 25% that you need to complete your effect. Until then, you can just pull the same default emitter in 25 times and tweak each instance to match what you want. You can add/disable modules in systems, making it possible to do most of what you want inside a system. Because we maintain inheritance, systems track what happens to the original emitter and synchronize with those changes.

Looking great, But there is an issue on my side (using the Source version)
I can't see the Translate or Scale Widget in the Editor. It only shows if I'm using Wireframe mode. The rotation one seems to work.

Using UE 4.20 source (release). With Geforce GTX 1080 (Driver: 398.36).

Tested with preview Shader Model 5 and 4, same results.

"Backlogged" status usually means it's never going to be fixed

This bug is making it really hard for coders. It has 64 votes too. I really think they should be doing something about it.

Something strange, I started the installation process and next noticed a new version of the Launcher was available, updated it and now show me only 4.20.1 Preview 5.
This is the right one?

Fixed! UE-61946 Arrays on multicast events called from the server are not passed to clients

Thanks, was wondering if this was a bug or if I needed to rework something in my event.

UMG has an issue with a double outline on text that has a shadows enabled. I posted this in the questions section but haven't heard back. Please see before and after image.

In 4.20 I have got a bug with tessellation in viewport.
In closeup it look ok, but when I zoom out i get black outlines and another tessellation bugs.
Same scene tested in 4.19 and works ok.

I hope UE-62069 gets added in one of these hotfixes since I noticed it got fixed. It's a huge issue for me and having to wait until 4.21 for that specific fix would be a bummer.

Am I imagining things or does the editor launch a bit faster with 4.20.x?

It did for me initially, but then it slowed down to about 4.19.2 loading speed when I opened saved project (which was a TPS template saved as a project).

For 4.20 , There is strange bug .

When I start VoiceCapture inside android , runtime permission shown up and I can see captured data after the app start , however if I close the app and run it again, VoiceCapture state become OK but No voice data . 0 bytes .

I tried to debug that with android studio profiler , and I found this error pop up when the app start for 2nd time : E/AudioRecord(24604): start() status -38 , and then bytes are always 0 . I dont know even a right description for this case to report a bug about it . could anyone help .

Here is the full LOG

Oh, I have the exact same problem with 4.19! I already thought its something wrong only for me, great to hear you have the same problem.

Does anyone know more about this?
