    Welcome to making of "Town square" map in UDK

    Welcome to making of "Town square" map in UDK

    Introduction:

    Hi , here i wanna share with you lots of experiences during making this scene named "Town Square" . this is the scene I've done as visual target to start a new project and in this case i should define a process to make an environment fast , instancable and organic without wasting too much time on sculpting . time was my client's basic limitation.

    this is final shot video and some screenshots , completely playable with real world size ,based on their concepts and color-scheme that will follow then :





    Level Design:

    the process for making a scene like this in platforming genre starts with a blockmesh comes from designer . with just simple meshes designer decides what pacing he/she is looking for versus gameplay time and having fun with considering metrics of different mechanics and using them wisely and test their choices with play testing a lot.
    some screenshots of our blockmesh done by my friend Mohammad Dabiri


    Concept:

    after a lot of iteration and playtesting, some screenshots sent to concept artist which decides what are these blocks.
    depends on your concept artists this step is so fast and helpful


    note: Art director controls visual uniformity as well as manage artists not to cross the boundaries.
    in this scene the art director was the concept artist as well
    so these are the concepts that i should work with:


    note: we have different methods in different studios and different genres about concept in-game
    1-you can have some beauty shot which contain taste of the environment , level of damages and lots of possibilities may occur in a level , and environment artists will take care of the rest .
    they decide which elements of the shot can be helpful in different parts of their scene
    2-like the way that we did , blockmeshes turn to concept and then environment artist will come through.
    there are many more methods which all depends on the studio, time and money.



    Modeling:

    so i got the concepts and blockmeshes as well and start making the scene.
    i handled all visual parts like environment,props,textures,shaders,particles,light ing,dynamics(water and movable objects ) as well as post process .
    before i started to work,i should make some vital decisions to define a process , process should meet their goals with considering their limitations (Time ,people and money)
    so i decided to make low ,simple assets with high quality tilable textures.



    the benefits:

    1-simple,fast and productive assets

    2-UV generation is so fast

    3-different textures on simple geometries can give different feels
    4-with powerful painting option in udk you can easily break tiling and reach much more organic feel
    5-you can use movemods(some geometries feed with the same tilable texture, help to have nice silhouette and organic forms).
    6-for platforming genre ,iteration is almost the most important thing , instead of putting lots of time on sculpting a wall and using it in exact units and exact places , you have a HQ detail texture combined with powerful material editor (UDK) which gives you the ability to have highly customizable shaders . so one HQ detailed wall with single task turns to a nice texture and a shader with lots of variations and usage .



    so i started to work based on 2 inputs : level design,concepts
    and at first I started with Proxy(very simple meshes)
    proxy step helps designer to do last modifications if he/she did sth wrong.
    after that, i add some detail to proxies and turn them into final assets .


    Note 1 : your scene should be storytelling, if you had a story before creating a scene based on game story or an story in your mind , you can reach too much more organic feel. my story was simple; a group of people attacked to the town and its people try to defend themselves .


    Note 2 : before starting to model , think about instancable parts ,,, which part could be a copy of another or just a simple rotation of an existing asset . this save you a lot of time and memory and it's crucial for better performance





    UV:

    because we have simple geometries , UV generation is so fast, with simple projection you can easily unwrap all of them.


    Note: it is very important to keep uv size the same for all assets , this will help you to use one material on different assets without copy it and change its uv coordinate and this is a good thing for performance.



    TEXTURING:


    this is the most important part in my process . while assets are responsible to keep low with perfect silhouette,textures help player to accept environment as an existing place.
    for texturing i had a color key concept that another concept artist painted it on my 3d geometries and i should use it as my reference


    texturing pipeline is vary ,depending on your time and your goals, especially to derive normal map for games ,,, crazybump , nDo , nvidia all have their own benefits and drawbacks but for my own purpose which normal map is very crucial in my process i preferred to use ZBRUSH.
    Zbrush do excellent job and derive normal map exactly from actual geometry and the result is awesome.
    beside you can have different sets of for example bricks and combine them with udk painting option and the result is awesome. in this video you could see the effect of normal map generated with zbrush in UDK as well as some of my textures :






    And diffuse:
    material editor is so powerful as well as painting option .
    in this video you can see how well textures blend with each other and some of my shaders :






    collisions:
    i should mention that don't ever forget to make collision for your assets , especially those that depends on gameplay like ground or in my case pillars and some walls . remember,you and your teammates always need to play your scene .

    Dynamics:
    when we speak about dynamics , first thing that comes in mind is particles and that's true but without movable objects like windows moving with the wind,water ripples or interactive elements , your scene looks very solid .
    in UDK you can control dynamic objects with : 1- matinee2-shaders 3-animation comes from external packages like Max or Maya
    so i will explain each method with an example in my scene :


    my willow tree:
    Built in 3ds max, completely organic and Tfrag(stands for time fragment is an asset which is unique without having plan to instance it , i heard this in naughty-dog talk at first )
    its movement controls by wind shader and for getting the best result i have used a powerful plugin from Epic called pivot painter .
    pivot painter is a 3ds max plugin helps you to paint vertex color procedurally and more accurately .as you can see willow leaves move with the wind quite dramatically and help player to feel more alive.

    PivotPainter :http://udn.epicgames.com/Three/PivotPainterTool.html
    wind shader:http://udn.epicgames.com/Three/WorldPositionOffset.html

    the wind force controlled by matinee, sometimes is calm and sometimes is so powerful



    Rope and plants:
    ropes move with wind shader and thanks to Epic and its powerful plugin named pivot painter.
    plants move with wind shader but no more vertex color , i thought that was not necessary .



    wheel and windows:
    control by matinee, just a simple animation.

    water:
    for water I implemented Valve technology called Flow map,it's not sophisticated, just wrapping normal map uv coordinate based on RGB map represent vector direction helped me to slow water around edges and back and force ripples near the edges ,very subtle very effective.





    Particles :
    thanks to very Powerful particle editor (Cascade) in UDK, I made wind particles with some variation , dust with leaves , falling dust and stone and loop them in cascade or with matinee .


    Lighting:
    some people think that lighting is quite simple in recent engines with differed lighting and GI calculations and real time AO but in fact they think completely wrong . you should know exactly what you want , how can you compensate lack of GI in some areas , where does color bleeding happen and do you want it or not or try to exaggerate that .
    but in this case UDK does a very good job and you can handle whatever you want with its lighting tools.
    after that with Post Process you can meet whatever is in your mind.
    Don't forget to have a proxy light rig at first to see the result of normal maps.

    After all this is the last video of Town Square map again for those who want to see article contents visual again:



    I hope this was helpful for you

              Amazing piece of art!

              Your work is visually stunning. This map is created by virtual atmosphere, lighting, solid textures, details, particles, vegetations, skyboxes, concept, shader diagrams, and other else I don't remembered. They're all rocked! 5 Stars!

                Hiva61, The work and video is amazing, and I was wondering if it possible to slow the camera down in the main video for it was hard to really appreciate the work that was done as the camera speed by each scene really fast for my eyes. Once again great work on the art.
