如今有许多HOPA/冒险游戏使用3D建模&渲染解决方案来制作2D场景的图片。这包括用3D来创建场景，加入许多3D道具，家具、植物等。

我将在本文提供一个我们团队所使用关于如何快速为所有3D场景中的对象设置正确大小的技巧。我认为这一技巧不但适用于制作HOPA/冒险游戏的美术人员，也适用于所有处理3D场景的相关人员。

首先，我们以两个人的3D模型为例。如下图所示：

一个站着，一个坐着。要确保站立男子的身高是180cm，或者是你所认为的普通男人的身高标准。而坐着的男人也要有同样的体形。如果你的工作室之前就制作过3D模型，你就无需制作这两个模型，你肯定已经有了相应的内容。（确保你删除了角色服装、骨骼，只保留多边形）

例如，你想为一把椅子设置正确的大小。让那就让男人坐到椅子上，调整椅子的比例，将其调整到合理的大小（你很容易就能看出下图中哪一个比例是正确的）。

记住在这整个过程中，永远不要去动男人的比例。

如果是可容纳三人的沙发，你可以令三个男人并排坐到沙发看看效果：

任何人类使用的东西，无论大小都可以如此操作：

这不但可作为道具大小的衡量标准，还可用于设置门、走廊的比列：

总结：使用两个男人的模型作为一般事物的标尺。在某些情况下，你可能需要女人的模型。当然，也有一些需要打破规则的时候，比如当你需要制作不自然大小的对象来实现特定美术目标时。（本文为游戏邦/gamerboom.com编译，拒绝任何不保留版权的转载，如需转载请联系：游戏邦）

HOPA/adventure game art: How to set the right object scale

by Junxue Li

These days lots of HOPA/adventure games use 3D modeling & render solution to make the 2D scene pictures. This involves constructing the scene in 3D, putting in lots of 3D items, furniture, plants, etc.

In this article I offer a tip used by our team, about how to quickly set the correct size for all the objects in a 3D scene. I think this tip is not only useful to artists who work for HOPA/adventure games, but also to guys who handle 3D scenes for all kinds of purpose. Here we go.

First, get 3D models of two men. Like this picture.

One standing and one sitting. Make sure the height of the standing man is 180 cm, or any size you consider which is for an average man. The sitting man should be of the same build. You don’t have to create those two models, if your studio has made 3D before, you must have them. (Make sure you have deleted the character rig, bones, only keep the polygons.)

For example, you want to set the right size for a chair. Put the sitting man on the chair, and adjust the scale of the chair, to the reasonable size: (You can easily see which one below is right!)

And during the whole process, remember never touch the scale of the man.

And if it’s a sofa for three, you can juxtapose three guys to see if they can fit in:

And anything which is used by human, big or small:

Not only as the measurement for items, but also for doors, passages.

Conclusion: use the two men’s model as a ruler for generic things. And in some cases you may need women’s models. Certainly, there are occasions to break the rule, when you need to make unnatural sized objects, to achieve certain artistic goal.（source：gamasutra）
