Follow a practical guide to building 3D cityscapes for games. IAuthor Adam Crespi constructs a city block in 3ds Max utilizing low-polygon modeling and advanced texturing techniques. The course shows how to model common city elements such as buildings, intersections, curbs, and roofs and explains how to expand a city quickly and easily by reusing existing geometry in a modular way. The course also sheds light on simulating real-world detail with baking, lighting, and ambient occlusion techniques and offers a series of best practices for exporting to the Unity gaming engine.
The next step in producing a model is to check and make sure that the floor to floor height matches, to do a test clone of this. That way you can adjust the mesh before unwrapping. It's important to get the mesh right before putting an Unwrap UVW Modifier on. If you change those vertices in the model, the unwrap will be invalid. We will check this by using the Clone Option dialog. I'll switch into a front view and take the module I had previously. Press spacebar for selection lock and make sure my axes constraints are on Y.
I'll register the snap here on the bottom right or left, hold Shift, and drag up until the module clones to the top. In the Clone Options, I will make the Number of Copies 6, as an Instance. Stepping back to view the construction shows me a clone nicely, that the bottoms and tops match and all the windows line up with the shape. If I switch to a wireframe by pressing F3, I can see cleanly that my mesh lines overlay the gray shape lines and that from top to bottom has a 10 foot repeat.
We know it's 10 foot, because this Plane was 10 by 10. At the top and bottom, because of the 10 foot repeat, we see that we have no gaps. Now we can delete the clones. This is merely a check to make sure that this module will work correctly before we texture it. In this movie, we have looked at the interim step of cloning and checking. It's important to do this to make sure that the mesh works before unwrapping. That way if there is any issues that need fixing, minor gaps, etcetera, they can be taken care of and the unwrap will be done once, instead of going back and repeating work.
