Diversity using modular pieces part 3

In this post I’d like to go through some tips and tricks to help spice up your environments. I used the same tricks to create Abandoned Mine for The Haunted. See my previous posts for more information regarding the creation of Abandoned Mine.

Before you start working on a level I think it is a good idea to put up some guidelines about placement of assets, painting of material types, the color of light and so on. An example of a visual guideline could be that grass should be placed close to rock modules touching terrain to make the rock modules feel grounded. Guidelines can also directly affect the gameplay of your level. How is your levels light colored? Maybe blue light should always be used for passage ways and red light could be used to mark areas with power ups. Having some well-laid guidelines will help the general impression of your level.

Let’s start out with the first image. Now, this is a simple layout with a couple of rock modules some light and a terrain layer. The problem with this shot is the blend between the foot of the rocks and the ground texture. What I usually do is to start with raising the terrain so it connects more naturally with the rock modules. The terrain layer is a simple but powerful ally. Don’t rush and try to fully utilize the few but powerful terrain tools to get your blend right. With the smoother height blend it looks better. However, the contrast between the rock and ground texture is still very apparent.

The next step is to add some texture variation. I used the same rock texture for the ground that I used for the rocks themselves. Paint on the raised terrain and focus on making a nice gradient from rock to sand. You can mix in more than one texture if you want. I used a third texture of some gravel for the last image. This way my blend goes from rock to gravel to sand. Think about the guidelines for your level. Where should you use your materials?

If you are making a level that uses the same rock modules a lot it can be a good idea to think about vertex painting the modules. Since Abandoned Mine takes place mostly inside I created two different rock textures for the rock modules. Make sure the textures have some nice contrast and don’t look too much like each other. Just like I mentioned in my previous posts about the rock modules it is very important that you take your time when creating assets that will be used a lot. When I was satisfied with my textures and had the materials set up I proceeded to vertex painting my rock modules to blend between my two textures and create more variation. This can be a slow step if you have a lot of modules placed on your level. But it is, like all previous steps, important to take your time. Take a break if it gets too boring and return later with virgin eyes.

Now we have some nice blending going on between the rock modules and the terrain layer. The rock modules themselves are vertex painted to give some needed variation. At this point I proceeded to adding grass and some detail rocks. Think about the placement of these assets to maximize their potential. Grass can be placed close to your rock meshes to help make them feel more grounded, or rooted. The smaller rocks can be placed to directly affect the shape of your rock modules. From this point you can just continue adding more assets relevant to your level or tweaking things like placement and light.

Lighting in UDK #1

In todays post I want to show some progress on the new version of the award winning level Lost Temple. For the retail version of  The Haunted we are relighting and updating all current levels. With the Unreal Development Kit Epic has introduced a new lighting solution called Lightmass and we of course want to take advantage of it. For this level there was already pre-existing lighting set-up. However, when turning on Lightmass and the new Color Lookup Table feature everything goes crazy.

I started with removing all pre-existing post-processing effects. The Color Lookup Table, or LUT for short, is a new feature that replaces (or combines with) the old post-process scene effect. It gives you better and more accurate control of your post-processing. After removing the pre-existing settings I went on to delete all old directional and skylight entities to get a fresh start using a new dominant directional light. I wanted to use the moon as the directional light source (the moon reflects sunlight in a white/grey maybe even slightly yellow tint even at night). I had to do a lot of experimenting before getting the results I wanted. In the end I used one dominant directional light coupled with an exponential height fog entity to get the effect I wanted. The moon was moved from a full 3D mesh to a single plane using a new material with an halo to get it to blend better with the skymap and lightshaft effect.

I used mostly cold colors outside highlighting portals and passageways with warmer torches. Interior of the level are warmer lit by living flames. All levels in The Haunted has its own unique type of environment danger. Temple is no exception and during play you might experience the sky going from cold blue to hot red with trees burning and fire stones raining from the sky.

So now that we have our basic cave it is time to break it up a bit and create some variety. Take some time and think about what kind of assets could benefit your theme. This is still a basic pass of the level so try to think simple. I built one wooden beam module that I could break up the rock formations with. I also created rail track modules which can be placed and connected into whole rail track systems.

For the lighting I started out with identifying the possible light sources for my level. The lava, the holes in the cave formations, electric lighting, torches and lamps. I copied part of my level into a new map to test and experiment with the lighting for quicker light builds.

When lighting your level think about the contrast between colors as well as brightness. I want the level to be dark and moody and I try to keep the contrast between light and dark clear. It also benefits the player if you try to incorporate gameplay into your lighting. Try to use the lights to guide the player through the level.

Try to active dead space with either light or using art assets. With dead space I mean parts of your level that is uninteresting to the eye, like a long length of rock, or parts that look very much alike. Try to separate these areas and make them unique.

Here is a sneak peak behind the scenes on The Haunted. At the moment I’m working on placing rock assets on a new level. For this level I  started with creating assets that are scale and rotate friendly. I want to do this because the level consists of a majority of rock walls and formations. This way I can easily create interesting cave formations in no time.

I used a sculpt tool to get the right shape and feel of the meshes and then built low poly versions and baked normal maps. Try to keep the modules clean and optimized: in my case I will be using them a lot so I want them to be as cheap as possible. I use one material with 3 1024×1024 texture maps.

Make sure that the base modules are well made. Try to make each side interesting and unique. When they are – it is very easy to create cave system out of very few modules. In this particular case I used two unique rock modules to create the scene. Don’t be afraid to scale, stretch, squeeze and rotate your modules to make your formations more interesting.

The video shows you how I easily build a unique wall quickly using just two modular rock pieces. The light consists of two basic point lights: one blue and one orange. Nothing special at all.

Once the base walls are in place the next step is to explore how to break up and create more diversity in the formations using additional modular pieces and lighting. I will get into that more in part 2.
