    It's nothing to do with simulating human eyes, and everything to do with simulating the sort of effects humans are used to seeing in cinema and photography. Also, Depth of Field in general is an effect we are long used to seeing in game engines, not sure why this sort of thing is news to you.


      I'm doing some tests and for now I can't pin-point where the issue is, but 3 projects I have been developing are showing frame rates by half when packaged, not happening in editor thou. I think it is some issue with material output being doubled, which is a severe regression issue. The development was being made in 4.17 and I am doing the tests on 4.18 and 4.19 to be sure it appeared only in this 4.20p1. Once I finished these tests I will start to mess with the materials and see where the issue is, but I can tell pretty much it is with CustomNode node, going to make a small project showing the issue and reporting with the submission form.

        Nice, love your work. But I'm still on 4.15 Is this going to be backlogged or? Just wondering because it keeps getting put back. These seem a bit prohibiting for an upgrade!


          Could someone please help me parse this? It is either written badly or I am just not getting it since it's 3am in the morning.

            We've seen some reports of Niagara crashing when you create an emitter. This is due to an unresolved bug where the project isn't getting the proper config options copied over. The fix is to go into the Project Settings for Niagara Editor and import the following config file. You'll need to rename the file from .txt to .ini.

                This one worries me. I suspect it's due to all the rendering changes in 4.19 for Temporal Upsampling etc...

                Could it be this?

                That ticket has the same symptoms, but It is not restricted to UMaterialBillboardComponent only.

                The best summary that can be given is as follows:

                Range activities on certain combination of hardware and software cause progressively deteriorating hitching and memory leak, both in editor and shipping configuration cooks.
                That issue should absolutely be the highest priority one to fix.

                  It's just a snippet of the early draft of the Release Notes for 4.20. There will be additional information for Mesh Description but it will be more high-level and expand a little on that paragraph. Once the new mesh format is more rounded out there are plans for a documentation page to go into more detail.

                    None that I've been made aware of so far to call out for release notes. I'll check with the engineer before 4.20's release and update the existing doc page if there is.

                      Is this as in a new UI or improving the existing UI? or is it all the related editors out of the box?


                        I'm running into a couple of weird issues. It seems like the "depth blur" settings in CircleDOF no longer work at all, which is a shame, since I like being able to have some blurriness on both the background and foreground, but the minimum F-Stop value of 1.0 makes this essentially impossible.

                        Also, at least one of my levels seems to have lightmap corruption after porting it to 4.20. It's possible that this is something specific to my project, but it's definitely strange. Most things look fine, but a few surfaces are inexplicably either solid black or extremely bright.

                        I'm curious about the hitching/memory leak issues that a lot of people are reporting, since I haven't been able to reproduce that at all across multiple machines. It seems like the issue might be difficult to track down if it's really inconsistent.


                          please fix this too:

                          and add this:

                          thank you

                            Unreal adds: Directional Gravity for Characters.

                            It has been requested since forever, to enable character BP to walk around spherical planets for sinlge player and multiplayer, right now it´s only posible with paws,

                            That's a bit of a niche feature. Still, there are several plugins that enable this functionality. And it hasn't been requested since forever. A few people here and there ask about it constantly, because they aren't aware it's already possible.


                            I'm getting a lovely bug where the whole editor UI goes super bright. It's like every element is getting a brightness tint applied. Any one else running into that?


                              One more version where CLion integration is broken Have to generate stuff manually again.

                              Still getting the following with 4.20 Preview 1:
                              /Users/Shared/Epic_Games/UE_4.20/Engine /Users/Shared/Epic_Games/UE_4.20/Engine/Binaries/Mac
                              ERROR: UnrealBuildTool Exception: Unhandled project file type 'CLion
                              Aaaaand the fix is scheduled for 4.21....


                                I would like to point out that an early version of the Geo 2.0/Mesh Editor is in this version! You can enable it by entering this command "MeshEditor.Enable"

                                There's also a lot of new Blueprint nodes as well under "Editable Mesh" which are related. I don't know how to use these though.
