It’s interesting to note that the biggest difference here is made by being able to tweak the Dynamic tonemapper, the rigid system from the previous months was very hard to work with for me. Also the exponential heightfog is just great for getting moody colors in there.

Ship is nearing completion, enviro still needs a lot of love. Got totally inspired by Halo Reach for it though.

Here’s what I have so far:

The environment is almost done. Some tweaks left, set up the materials for the far-away terrain and add the ocean in the distance, and optimize the trees (they’re not so good for performance atm).

After that I’ll model a wrecked Curtiss C46 Commando plane to lie on the rocks.

The custom mesh for the waterfall:

I’m looking forward to the day realtime rendering becomes the standard.

This is my result:

The tank tracks are another type of blend, this one’s about the snow on the ground.

I was asked to post my node layout on my blog, so here goes:

The base mask for snow coverage is calculated by using the Red vertex color channel (you can easily paint onto one channel only in UDK, great feature!) and a heightmap. These are combined together to create a transition effect with the heightmap, where the vertexcolors fade out. Clamped at the end to prevent extreme values, just for safety.

Using the Green vertex channel, we calculate a varying number for the mask’s hardness. 20 is the ceiling value, a 1 is added to prevent powering to 0 (bad). The invert on the vertex color is just to make sure the default value is hard (default vertex color is 1,1,1,1).

Both groups are combined by powering the raw mask to the hardness value, adjusting the contrast. Clamped for safety, though technically not necessary since we’re only powering a value of max 1to20,resulting in a  1 anyway.

The mask is used on 3 LinearInteroplate nodes, to blend between snow and non-snow diffuse, spec and normals. Since I had the heightmap anyway, I just used it for a quick parallax effect on the diffuse (I should apply it to normals as well…).

Total material. Nothing too complex, only 63 instructions which really isn’t expensive.

I recommend doing this in UDK only, since painting vertexcolors is incredibly easy there.

The entrance gate at the back is still very WIP, but I finally threw out that useless big placeholder mesh there.

UT3 is engine version 3809, UDK is engine version 5860. About two years of extra development and probably a few million dollars more spent on development.

Just go download it now, it’s free!

A lot more decoration was added. I did some work on the surrounding environment so there are cliffs and mountains around. Still need to place more in distance so the level doesn’t seem to end abruptly in the distance.

the ASC trees look really good, too bad there’s only one of each kind so repetition is rather noticeable after you used it a few times.

I added a non-functional door under the bridges, to break up the empty space and so the building bases look like they have some sort of function (locked cellars or whatever).

Still far to go, I need to build two floors on top of the main building, and the front gate is still just a placeholder. Those are next on the list.

BSP should be pretty much completely final. All brushes have materials assigned now. I placed some important and less important static meshes around to get more of a sense what things will look like. This showed me that in some places the BSP needed a bit of editing to better accomodate the meshes.

There’s Heightfog in there, just quickly placed and tweaked to get a sense of things. I also did some fun tricks with the water, but I’ll talk about that later.
