      Hi all,

      We are working to release a Hotfix update to 4.9 this week. It will help to address a number of issues, but of course not everything. We'll post here with the full scope when it's available.

                The hotfix is great thank you guys very very much. No word though on the packaging problems that caused 3-4 entries to not be finished this months jam? Really caused a headache for our team and ended up not packaging right anyway.

                  Ah, saw new one was released. Will wait to hear from others if this includes enough fixes to switch to it and not have issues with PC based projects.

                    Question about mobile lighting and shadows / performance.

                    Hi everyone.
                    I have been gone from UE4 for 2 months but im back.
                    Currently updating the engine which will take a few hours.

                    So was hoping someone anyone who has tried and used the new ue4 mobile features... could tell me how the performance stacks up to previous versions.
                    Im super excited to test it myself. Shadows... omfg man... shadows. That is awesome.

                    Hows performance on lower end mobiles? Has this improved?

                    Engine better update now i am so amped.
                    Free UE4 things available. More coming


                      Hi Nsomnia,
                      I was one of those GameJam Teams this month that couldn't compile my game. The root cause was excessive file name size. With over 600+ over sized file names from Marketplace asset packs, I just flat didn't have the time to develop a game a resolve out all those file name issues in 4 days time. I will probably have a compiled version of my game latter this month as it's tricky work to rename assets inside of a project once it's started (How do I know this, don't ask!).

                      Just a note of clarification: It's the large directory names causing the problem, not specifically the filename. My directory names are HUGE and they are causing engine failures.

                        One interesting side note,
                        I just installed the 4.9.1 engine and tried doing a test run of my Sept 2015 GameJam project. After recompiling the shaders, I got an impressive 3-4 FPS increase of the game speed IN THE EDITOR! Wow! Thanks Epic! I will try recompiling the game later this evening.

                            I still have the aliasing issue like koola and the performance is still 15 to 20 FPS lower than on 4.83...


                              I still have the problem in 4.9.1 that if I compile one BP (which has a lot of childs) then one child turns dirty (so compile fails) and I have to open the BP of the child and compile it manually (then compiling works). It's a cyclical dependency issue since in the child I am spawning an actor which is child of itself (child of the child of the parent) and store this actor reference in a variable of the parents type. I already got this bug in 4.8 and I really hoped these annoying cyclical dependency issues would be finally fixed in 4.9...
