    You want to bake cloth sim? Or bring a cloth object to run within UDK? Within UDK, just tell UDK what bone is the cloth bone. Within Maya, bake simulation to blendshapes, then export.

    Which one do you want? As they both have different workflows.

    I'm currently messing around with UDK mobile and for some stupid reason my meshes show up as checkerboards in game (Mobile previewer, standard works fine).

    Currently browsing around testing various approaches. Got any ideas?

    Do you have the materials set for mobile materials, or just the normal expressions?

    I thought there would be no difference Kite. Do I have to check the "Auto Flatten Mobile" option and set it up in there? No expressions at all?


    EDIT: Well that worked. :/
    And here i thought we'd be able to use the material editor fully :)

    EDIT: Oh well. I'll hopefully have a level up and running soon then (all assets etc are complete more or less). Might chuck out some dough for that dev license.

    i think he's talking about having dynamic cloth in UDK.
    I was, but I still to appreciate the tip from tristamus :)

    You don't have to pay Epic till the very end. You can get by on your apple dev lic.

    No idea if this has been asked and if there is an answer, But is there any way of stopping steam from displaying me as in UDK? It's just that sometimes i can't be asked to work on something and normally i'll tell the people who i'm currently working on a project with that I am working on it, But with it showing if i'm in it or not, It makes it hard.

    Dont install UDK from Steam :)

    Then set you steam chat to offline, or just don't have steam running when you run UDK.

    It's easy to disable Steam in UDK but hard to find out how! :poly116:

    In your UDK directory - UDKGame\Config\DefaultEngineUDK.ini
    Right near the top, set bEnableSteam to false.

    Pissed me right off too!

    If you are having problems with sync then it's the trigger for the event (guessing you have one long animation and one long audio track). If you want UDK to drive it, then you need to:
    • transcribe the recording.
    • export phonemes/mesh from xsi using FaceFX. Be careful with the text file that lists the frames/phoneme. No blank spaces.
    • In UDK start up FaceFX.
    • Load text and audio.
    • Edit phoneme chart to fit the text.
    • Link each XSI phoneme to the FaceFX phoneme chart, also link the text to audio track.
    • Play back the audio and fix all the phoneme errors from the automated function.
    Save and save often, it crashes and some parts have no un-dos.

    Looks like a normal map...
  • d1ver

    d1ver polycounter lvl 12
    Hey, Lamont, I'm pretty sure it has something to do with either normal map or lightmass. But it isn't any specific normal map - since this stuff is practically everywhere. And this wall(and floor too) has a tilable material this is tiled quite a few times across the surface. So it сan't be some sort of a blob on a normal map itself, but rather the way NMs interact with the lightmass.
  • Lamont
    Offline / Send Message
    Lamont polycounter lvl 11
    Yeah, there's a setting to use the normal map like that with Lightmass. Are you in UDK Mobile?
  • d1ver
    Offline / Send Message
    d1ver polycounter lvl 12
    No I'm not. I'm using the August build. Maybe I should update...
    And what kind of settings are you talking about? I know that Epic added normal map data into baking algorithm, but that's about all I know. I guess I should've looked through UDN and Lightmass settings before posting. I'll check it out in the morning.

    so yeah, here's the switch that helped. Although I still don't get how this stuff works and what caused it. What I did was basically turn off the feature of using NMs with Lightmass. Seems like could be bugs. I guess I should update. And yeah - it hasnt completely gone away - on more curvy surfaces things are still weird.

    Have to try to update. Weird that no one seems to have stumbled upon it. I wonder what I did that's so different.

    Hey guys, I've been looking around for an answer, can't find one yet.

    I've been building the GUI and HUD for my group project, and I've been trying to make a main menu.

    mainmenuKismet.png

    The setup is for a UIscene to overlay a matinee camera loop that i made as a backdrop. The thing is, I can't seem to find a way to link the button in the UIscene to this kismet, nor can i find an event like "on scene closed" or something. In fact if I could figure out how to get that kind of functionality, that would be great for a lot of other things in the game as well.

    Hope I was clear enough!

    P.S the problem at the moment is that if i click the "start game" button in the UIscene, it closes the scene, and then the matinee just loops forever.
  • doggett
    "The thing is, I can't seem to find a way to link the button in the UIscene to this kismet"

    I haven't tried much of kismet/Ui Scene, but The 3D Buzz tutorials seem pretty comprehensive on the subject... [URL="http://udn.epicgames.com/Three/VideoTutorials.html#3D Buzz Video Tutorials - Using UDK"]Link to UDN Video tuts[/URL]
    That may give you the answers your after!


    MY problem with UDK (Dec build)...
    I duplicate a mesh or material and after a random amount of time as it's not in use in the scene UDK unloads it.
    Problem is... it won't allow me to fully load my package or the mesh/material (the option is greyed out)

    So I tried saving all and restarting Unreal then opening the file again and the mesh/material has dissapeared completely.

    I've searched for a solution to no avail so far.

    It's happened before where materials just dissapeared (ie. if I reimported a mesh and the texture slots no's changed) so I had to build them again.

    It's like it auto-cleanses!

    you can. i personally prefer it, tho when i was talking with a friend who is helping with our hud for a project, he said that he now prefers to do it in kismet since they removed the old UI system.

    Hey Lamont, thanks!, found what I was looking for, Level Event within the UIScene actually can link up with a remote event in the main kismet, it's just that the red cross wont change to a green tick, even though the connection is there.
  • NoctyQ
    This might be kind of a stupid question but if I don't ask it I'll probably feel insecure and confused for the rest of my life.

    #1 - Is there any way to have a lightmap merged with a layer of AO?!
    #2 - Could I have a dynamic lightmap that works like AO in udk?(only filling crevices)

    In this case I want to have a tileable texture but still preserve some details I made from a very basic Highpoly. Normal map isn't relevant.

    I can easily make this with xnormal and photoshop but its a different matter when it comes to udk.

    I like using this setup in Marmoset Toolbag but it would be cool if I could either export the specific lightmap and overlay it in photoshop and then import it again or find another solution.

    Edit: This thread might not be as active as I thought. Would still love a answer anyway.
  • planaria
    was looking around for a tutorial or atleast a material picture breakdown of how to get the z up texture blending via a heightmap for models for when you want to put snow or sand ontop of a model into a scene for instance.

    i fail at search please halp !
  • Ben Apuna
    @planaria:

    What you want sounds similar to The Pit project Virtuosic is working on.

    EDIT:

    I think this one is exactly what you are looking for:

    Here's an interesting link:
    http://forums.epicgames.com/showthread.php?t=752085&highlight=tessellation

    seems as if the beginnings are already being added, just not yet fully exposed in the public releases.
    The screenshots of the tesseallations in the licensed copy got me pretty excited.

    But then again some of the exposed features ( dropdown menus, etc. ) in
    the November release were taken out of the Jan release.
    I hope that doesn't mean that they are backing out of implementing.

    Gotta stop playing the stone giant benchmark... The long wait in
    attacking a first stab at such a pipeline is killing me. ( gimme gime gimme )

    Also it is nerve-racking when the majority of Artists out there aren't
    giving input on new tech as it develops.

    Has anybody had any problems with Cascade with the January version? We have the December build at school and it seems to run much better than the Jan build. I downloaded the latest and it runs like shit on my computer, not sure if it's my ATI 4870 not liking it or if my Core 2 Duo isn't cutting it anymore.

    Either way, it's goddamn annoying and I'm going to try and download the December build to see if it works better.

    have deco layers been disabled in the Jan build? I was following a terrain tutorial went to ass my deco layer but couldnt add a staticmeshfactory. I then read that foliage layers had been disabled in favour of 'landscapes' which I had not heard of before, can anyone shine some light on this for me?

    Quick Q: I thought I'd import some models quick and dirty into my UDK scene without having unwrapped them. (It also has some open faces, but so did a few other props.)

    Slapped on a grey material, dropped them in the world, built everything and it looked fine.


    ...but when I 'play in viewport' the mesh isn't visible. Only the shadow is there. Any Ideas? What't the minimum requirement for having a mesh show up in game?
  • Ben Apuna
    @fearian:

    Did you save the package containing the meshes?

    Oh and open faces is not a problem at all.

    Not sure how new it is (seeing as I'm a UDK noob)

    But in the Material Editor, there's:
    SubsurfaceInscatteringColor
    SubsurfaceAbsorptionColor
    SubsurfaceScatteringRadius

    and the property:
    Enable Subsurface Scattering


    Apparently it's a bit new, but I can't find any documentation or tutorials about it.
