25,129. That’s how many times our Medieval House model, made with Ürban PAD, has been downloaded on TurboSquid. This model is free, but we could imagine that if we’d charged a dollar, we’d have serious money in the bank.

Our experiment is proof that Ürban PAD is an efficient mesh generator that easily produces beautiful models with clean, space-saving triangulations.

But the value of Ürban PAD doesn't end there. With it, if you build one model, you can generate a variation of it automatically and easily, export the models to Fbx and Collada, then upload all of them to your favorite asset stores.

You may remember Boris’s challenge – recreating a Turbosquid building with Ürban PAD. By adding variation to the model from the beginning, he was able to create five buildings in Ürban PAD in the same amount of time it took him to create one in 3ds Max.

A few of our money-savvy customers have already seen the opportunities possible by using Urban PAD this way. Join them and start using Urban PAD now!

P.S.: We put Boris to the test again with these medieval building packs. He adapted his first Medieval Building to create Medieval Building 1, Medieval Building Pack 2, and Medieval Building Pack 3. These packs are now available on these marketplaces:

• Turbosquid
• Falling Pixel
• 3D Export

Note: This morning we found the boss's post abandoned except for an empty M&Ms bag, a map of the Provençal backcountry, and some cryptic text on his screen:      

Boris had a temper, so I gave him a target.

Boris is our graphic artist. It took him a while to find what he wanted to do in his life. He had done a lot of jobs, you see. Some blue collar, some white collar. None of them gave the deep satisfaction of the craft you want to perfect for the rest of your life. And then he had this graphic art job. It was a get-a-bit-of-money job at first. But it affected him strangely. He was swung between pure bliss when something was done and pure anger when the tools got in the way. He had this image in his mind and wanted it on the screen, and, damn if it took some sweat, he would get there in the end.

He realized later that he had found his craft. Boris is more experienced now but his internal creative spirit still works the same way. He draws and designs as others fight. He may be the reincarnation of a Viking warrior. Exchange the axe for Photoshop/3DSMAX and you get the idea. And when something is well done, he goes for a smoke outside the building. In the blistering heat. We're having a hot summer this year.  

So when he told me he had a bit of time, I gave him a target: a TurboSquid building:

The plan was simple: redo the building using Ürban PAD and show how, when you do it this way, you finish the building more quickly and can turn it into an infinity of buildings.

He said "grumpf" and walked away with a dark glint in his eyes. You can see the image below.

I'd say 'mission accomplished.' The building was created quickly and easily and the variations are only a click away. It was a good thing. Boris almost smiled. What do you think?

Yesterday, when I asked him if he wanted to see this blog post, he said "no, whatever, pfff" and turned to his screen. He had a new target. 

This week: We're rolling out Boris' buildings on TurboSquid. Some are free; others are available for a small charge. All of them are handsome, good-looking, and waiting to be used in your game or simulation.

Almost finished! Today we tackle the roof of our medieval building, which in this building refers to the composed upper part of the model. The roof (the topmost part of the upper level) took about a day, and randomizing the pike placement took less than 5 minutes: 

We also added some randomization to the mix by making the addition appear only half the time (this is the Maybe rule in the Filter rules of the Sector Editor catalogue, which is pretty handy if you want some quick, easy variation).

When this sector is linked to the sector we created in Part 2, the resulting medieval house can be used as a centerpiece or combined with other models to create a larger scene.

Postmortem: since the ground floor stayed the same (except for the archway), we saved the most time on the upper level.

In the middle photo you can see the upper level by itself. This can be used as a separate building. We're thinking about continuing this project – either making a deformable building, or regenerating this one building a few times to populate a scene with a small village (there is a possible door on the upper level).

We're pretty happy with the results, which took approximately 2.5 days to create - under our time limit - but what else could we have done to make it better or more interesting?

Following up on last week's post, here's the first part of the upper level of our medieval building:

In this part of the building, we used more procedural features of Ürban PAD to get a bit of easy diversity. For basic uses, this means we can easily include variety in wall textures, window geometry, and props position. Modelling procedurally speeds up the work so that you don't have to create the same geometry manually or place the same prop at a different location over and over again.

We regenerated this level a few times to get some variation.  When we regenerated the geometry, the door and window placements changed. So did the sign position:

From the Gamr7 vault, here’s a little project we worked on back in March. The renders were featured on our Artilinki space, and here we’ll go into a little more detail about how we built the building with this post series.

The original model (above) was a medieval building with a basic ground floor and a more detailed upper level. 

Our goals:

• Reproduce the ground floor with the arched doorway
• Design a multi-level top with changing window positions and types
• Randomize asset placement : sign, lamps, and roof deco
• Blender render
• Get it done in less than 3 days. 

First step: creating textures and 3 meshes for this building - lamps, sign, and pikes. All geometry was created with Sector Editor. We used assets we already had on hand for this project, so no creation time was involved. 

Creating the geometry itself took about 2 hours. Here's the first image: 

The Shape rules came in handy for creating the arched doorway, while we used random extrusion to offset the stones from the doorway, making them look a little more authentic. Not bad for 2 hours' work.

The current Succubus release has a secret weapon that we’ve been working on for a while - context parameters. Context is a time-and template-saving feature in Ürban PAD 3.0. Access the context feature in Sector Editor by clicking anywhere in the gray area of the graph. When you do, you’ll see the Graph Context window, where you can set the parameters. 

So what is context, and why is it so important in Ürban PAD? Well, we talked about template linking earlier and why it’s interesting when you’re creating large or complex scenes. If you’re creating a scene with several kinds of windows, for example you can create several window types as separate sectors, then link them to a sector containing the body of your building.The graph is cleaner, and you can often improve your triangle count if you need everything nice and low-poly.

Before this new release, however, it wasn’t possible to adapt the linking sector template to the constraints of the new sector. You might need a building template with a fixed height of 20 units for one scene, while in another scene, you might want to use the same template as a linked template, but with a variable height anywhere between 18 and 36 units. There was no simple way to use one template in all cases.

The solution? You may remember the context feature that applied contextual change globally to a template or city in the Ürban PAD 2.x versions. We have generalized this feature for the Sector Editor so that context can be applied directly to templates.

When you bring up the Graph Context, you see a certain number of rules that are now subject to context. These include template features that are most often variable from project to project, like building height and texturing. Creating a context and making it overridable allows you to re-use the same template from project to project / scene to scene without having to create a copy for each project. While it's still in development and will be improved and expanded over the next few releases, here's a quick video of how it works in the current version:

As you may have seen if you've downloaded the new trial version, Ürban PAD now exports to Autodesk's .fbx format. We're excited about this for a few reasons, one of which is that it's now easy to work with your files in the Unity 3D engine, a favorite among Ürban PAD users. Importing your .fbx files to Unity is now easier with custom Ürban PAD scripts that make sure all your materials are properly assigned in Unity. The import workflow is documented in this video.

Having trouble viewing the video? Follow these steps to get your Ürban PAD models into Unity with no fuss:

1. In Ürban PAD, export your scene to .fbx format by clicking on the Export icon in the widget panel (top left). To select the Fbx folder as your destination folder for model export, just use the explorer button to choose the city_project/Fbx filepath as you're exporting.

2. Start Unity and create a new project.

3. Open the Resources folder of your Ürban PAD city project. Copy the contents of the Unity folder containing the Editor and Shaders subfolders.

4. Paste the Editor and Shaders subfolders in the Assets folder of your Unity project.

5. Open the folder of the Ürban PAD project that you used to store your model. Copy the .fbx model, model and texture folders, and the .xml file.

6. Paste the .fbx model, model and texture folders, and the .xml file in the Assets folder of the Unity project.

After you've completed these steps, you should see your assets in the Project tab of the Unity editor. Now you're ready to use Unity's powerful tools to polish your models and make them look nice and shiny (or dark and gloomy) for your game! Wasn't that easy?

Intermediate_Tutorial_3_-_Roof.wmv Watch on Posterous

Today we’re finishing off our generic building with a roof. This tutorial is fun, short, and to-the-point: we show you how to get two geometries for the price of one. We’ll explore those Filter rules a little further as we create a simple, streamlined top for our basic building.

0:18 – We start off by adding a simple texture to the roof surface. By this time, you’re already familiar with Random Texturing. We’ve included several roof textures in the Simplicity city project, so let’s add them as random textures in the Rule Node.

You probably also remember Global Random. There’s no need to click it here, as the texture doesn’t apply to multiple faces.

Voilà. We’ve just created our first roof. Easy, isn’t it?

1:11 – Now, we’re going to start creating our second roof using a Filter rule. These Filters can seem a little intimidating at first, but they’re easier to understand if you think about them as ways to procedurally select sides.

Here, we’re going to use a Filter/Maybe. This filter will select the face to which it is applied – in this case, the top face of the cube – a certain percentage of the time. We’ll set this percentage at 80, because Boris’s roof is nicer than a plain texture.

1:35 – Add a Ring rule to the filtered output slot on the Filter / Maybe node we’ve just created. This will apply the ring to the filtered face, and we can expect to this to happen in 80% of our building regenerations. We’ll make the ring length equal to 1 meter.

1:50 – Now, apply a PushZ to the Ring. This will push the ring up over the roof surface. (Can you see where this is going? Pretty neat, huh?)

We’ll give the PushZ a height of 1 meter, too.

2:15 – We’ve got our two roofs now, so it’s time to texture. Let’s attach the PushZ node we just created to the wall texture node. This makes the building texture uniform from ground floor to roof.

That was pretty simple and painless, wasn’t it? We now have a complete building with a uniform wall texture, windows that vary in size and appearance, and a roof. This building is an ideal candidate for a filler building in your Ürban PAD city. If you have one or two landmarks and want to use generic buildings to fill in the remaining space, you can make this one in under an hour.

Intermediate_Tutorial_2_-_Windows.wmv Watch on Posterous

Last week we brought you the first installment in our Simplicity intermediate series. You saw how we used Split rules and Filters to make a doorway and a ground floor.

Today we’re continuing our building and making windows. We’ll show you how to use a powerful Split operation to apply windows to the entire building, then vary their appearance with creative texturing.

0:17 – If you followed along with Friday’s tutorial and saved your work, open the base we created.

0:27 – Add a Filler Split to the remaining layers.

What is a Filler Split, you ask? Well, it’s a powerful operation that we like to use to create repeating grids along a surface and fill the gridded spaces with meshes, parcels, or other objects. Can you imagine how much time and hassle this saves when you have multiple objects to place on a surface?

Once you’ve added the Filler Split, go to its Rule Node (left side of the screen) to adjust parameters. We’ve done some math here and figured out that we want grid objects that are 2 units away from each other on the X and Y axes. We’re going to click Accept Internal Clipping.

Next, choose a parcel (Parcel Major in the popup box of options) to fill the grid spaces. This may seem a little unintuitive, but you’re basically placing a default parcel in the gridded spaces. The advantage of doing this is that you can regulate the parcel’s width and height directly in the Rule Node field.

In keeping with the scale of our project, we’re going to make the height and width 1.5 (or 1.5 meters).

1:17 – We’re now going to create window sills by applying another Split to these spaces created by Filler Split (see how versatile these Split operations are?).

We apply the Split to the internal layer – the default parcels – and give them a random floating value between 0.25 and 0.50. We split along the Y axis, beginning at Start (from the bottom up). To keep things varied, we click Global Random to apply a random split length to all the Splits. This will make our window sills uniformly varied each time we regenerate the building.

2:08 – Our next step is using a PushZ to extrude the sills. We give them a value of 0.10 (or 10 centimeters) so that their length will be uniform.

2:51 – Here, we repeat the PushZ extrusion for the window surfaces, which are the remaining layers of the Split. This is a negative extrusion with a value of 0.20, since we want the windows to slightly recede into the façade.

Notice that we also click the option Reverse Side Normal in the PushZ Rule Node box. As indicated, this reverses the side normals, which will assure that the window textures will be in the right position when we add them.

3:40 – We start texturing by attaching the sill node (the Split output slot of the sill Split node created at 1:17) to a texturing node. We select a single color since we want the sills to be uniform.

3:53 – We attach the sides of the PushZ node created at 2:08 to the texture node we created for the door frame. Door and window frames will be the same color.

4:10 – Texture the default parcels of the windows made with Filler Split using the Random Texturing option. (The Simplicity city project comes with three different window textures.)

You may remember Global Random from last session, and how clicking it is important if you want a uniform, randomly selected texture to apply to all layers. This time, we’re not going to click Global Random. If Global Random is not selected, a random texture will be applied to each layer.

By adding textures of varying transparency to our windows, we create the impression of lighting within the building.

5:27 – Connect the layers of the wall created by the Filler Split to the wall texture node. This will make the ground floor and wall textures uniform.

5:45 – We’re finished! Click over to Expanded View to see how our building looks so far. You might even regenerate a few times to see the wall and window variations.
