    Tutorial: Dissolve Material Effect

    Actual tutorial now posted here - http://udkc.info/index.php?title=Tut...aterial_Effect

    *Sorry for double post, should have posted it here rather than in project show off, my bad*

    I remember looking on Eat3D a few months back and I saw the material transition effect DVD. I thought the effect was amazing but I just couldn't afford the DVD so I tried to make the effect myself but without any luck.

    Last night I was laid in bed though and I had one of those 'Eureka' moments, whacked open my laptop and had another go and I almost got the effect.This morning though I got the look I wanted, I have no idea how similar this is to Eat3D's but as far as I'm concerned it works just as good. It reminds me of the vampires dissolving in the movie Blade.

    Note: Video is in GoW version of Unreal3 but it does work in UDK

    Anyway, how to do it:

    The Material

    You then need to create a Material Instance Constant of that material, then add a MaterialInstanceActor to your level and link the two. Then, in Kismet link up whatever sequence of events you want to activate the material into a Matinee, in my video it was when the spawned actor died. Then in the matinee, create a new group and link it to the MaterialInstanceActor in your level, create a new 'Float Material Param', then create a keyframe on 0:00 with the value of 1, then create another keyframe however far down the line you want the effect to last and change the value to 0.

    And there you have it. The effect can be added to anything really, it still needs a bit of tidying up, but I'll leave that to you.

      I believe Eat3D uses IF nodes for the transition gradient. Slightly different than yours, but as long as they both work.

        Ahh cool, when I get my next loan through I'll probably end up buying them but there's like 4 to choose from. I'd like to get the Hourences one, but I'm not sure how much I would get out of it at this stage. I'm sure it has lots of tips and methods which would be good to know, but I think it's aimed more for a beginner.

          Cheers, but that effect is just built in GoW.

            Is it my laggy internet? Or are the two associated images not fully loading? The Material editor and the black effects images both only halfway load. I can't see the bottom nodes at all.

              It must be your side, I did a full refresh and they both loaded fine.

                yea, I think Chrome is annoyed with my slow connection. It is working now.

                      Yeah sorry, it's a bit fragmented because I put it in the wrong sub-forum, doh. You can find a more detailed tutorial here http://udkc.info/index.php?title=Tut...aterial_Effect

                      Anyway, glad you got it working

                        Hey Pirahni,

                        Thank you for the tutorial!

                        I have been having some transparency issues when using this material setup on characters with more than one material and wonder if you are having similar issues?

                        For example I can see the eyes and teeth inside of the head of my characters. I think it comes from the translucent blend mode, which seems key in how this effect works.

                        Also, is there anyway to apply the MIC on top of existing meshes rather than rebuilding the base materials to include these instructions. (which is how i have gotten this effect to work)

                        Any info or help would be greatly appreciated! Thanks in advance!

                          I'v got the same issue, I'v found trying to apply this to a pawn with two materials doesn't give the right results but runs correctly with all my bots that have a single material.

                            Yeah I had the same problem to be honest. Luckily in my game I only needed to apply it to NPC's with a head and a body material so I just did the same material effect twice. I haven't gone back to this effect since then to expand upon it and I cant think of a way to apply it without replacing the whole material, sorry

                            I may have a look over the weekend if I get some time.

                              thanks for the response!
                              sounds like i should try single material characters
