    I've made a new Destructible Mesh Editor for UE4

    First off, not sure this is the right section. That said, I really want feedback from you content creation types.

    I've spent the last 6 weeks or so building a new Destructible Mesh Editor. I've coordinated with Ori Cohen and some of the guys at Epic, as well as Bryan Galdrikian at nVidia. They've been really helpful.

    Here's the blogpost I made about it:

    Precis: New DM editor, with all of the functionality for the Apex SDK. UE4 style, and almost all working at this point.

    And the Youtube demo:

    EDIT: That screenshot reminds me that I forgot to mention in the video that the cutplanes aren't visually how I'd like yet. I plan to attach a decal to them to project the texture as well as make the cutplanes themselves translucent panes.

    As I said in the video, I really want content creator feedback. USER feedback. I went into my bunker and built this, now it needs to get the final bugs fixed and out the door. Before that, I'd like to make sure it's as usable as possible.

    For coder types, I will be writing a bunch of articles about various techniques I learned building this.

    This is going to be biggest contribution to UE4 that i can think of. It will be interesting to see how Epic handles it.

    This is awesome Backov! Great work!.

      Looks good, but can you create a shorter video?

        Thanks, much appreciated. I'm really quite interested in feedback though.

        And no shorter video going to be made - it's not a trailer, it's a demo of a pretty complex editor.


          This is awesome Backov!

            Looks awesome and it will be very impressive when it's finished, congrats! Correct me if I'm wrong; so, when we shoot a destructible mesh and it explodes, can we shoot also the fractures and they get into smaller fructures with this? This can't be done in current system right?


              Ya, you can fracture the mesh up to 5 levels. Once it gets that low (or sooner, with the proper settings), it can become "debris" - which is a weird thing I don't fully understand. It's my understanding that it's visual only.

              The multi level fracturing can be done currently, but the assets have to be authored in Physx Lab. The ones you can make in UE4 currently don't support anything but a single Voronoi operation on chunk 0.


                Wow. I hope you'll get the help you need and make this a reality for all of us. Thank you for your efforts. I wish we see this on the marketplace very soon!


                  Thanks a lot!

                  But my goal isn't to see this as a marketplace plugin. I am submitting this for integration into the engine, as it's a drop in replacement for the current editor.


                    Yeah this one looks like a massive addition to the engine and looks extremely complex. you are so right.


                      Looks awesome. can't provide much better feedback :/

                      This interests me more. not the details of slicing and dicing algorithms, but how you learned to make a custom editor like that.


                        This is awsome I hope the pull recuest goes well.
                        My hat off to you !



                          Hello Backov,

                          I'm really interested how to implement this physics techniquies in UE4. Thank you very much!




                            So, there's now a pull request:

                            There's been quite a delay. I didn't want to hand it off to Epic until the final fracture mode was in, and that turned out to be quite an ordeal. Bryan Galdrikian at nVidia helped a lot, finally just stepping in and fixing the last bit of broken-ness, and now it works as well as it can.

                            I've fixed a few of the bugs in my previous demo, and streamlined a bit, but there's still outstanding issues that will have to be addressed with nVidia's help. Now that the editor is in the form of a pull request, I hope they will extend a helping hand.

                            Here's a new demo, just the Cutout mode, only 2:45 and hopefully no mic clicks.


                              awesome! good work backov!
