UV 投射修改器

投射Blender的logo到猴子头上

The UV Project Modifier acts like a slide projector. It emits a UV map from the negative Z axis of a controller object (such as an empty), and applies it to the object as the "light" hits it. It can optionally override the object's face texture.

选项

../../../_images/modeling_modifiers_modify_uv-project_panel.png
UV Map
Which UV map to modify. Defaults to the active rendering layer.
图像
用于修改器的image(图像),是可选项;你可以之将UV投射到任意位置。下面提到的Override Image(覆盖图像)选项将定义图像的应用方式。
覆盖图像
  • 当勾选此项时,网格上所有顶点的Face Texture(表面纹理)将被Image(图像)项中的图像所替代。这会产生图像重复的效果,这通常并非想要的看结果。
  • 如果没有勾选此项,修改器将被限制仅使用Image(图像)项中的图像作为其Face Texture(表面贴图)。
投影源
Up to ten projector objects are supported. Each face will choose the closest and aligned projector with its surface normal. Projections emit from the negative Z axis (i.e. straight down a camera or lamp). If the projector is a camera, the projection will adhere to its perspective/orthographic setting.
物体
Specify the projector Object.
X/Y 向比例和X/Y 向缩放
These allow simple manipulation of the image. Only apply when a camera is used as projector Object.

用法

常规项

UV Project(UV投影)适合营造出丰富多彩的聚光灯效果,同时也适合制作出别具一格的decals(贴纸)效果。

The modifier's Image property is not generally used. Instead, a texture mapped to the UV map that the modifier targets is added to the object's Material. This allows you to prevent the image from repeating by setting Texture ‣ Image Mapping ‣ Extension to Clip.

透视模式相机

When using perspective cameras or spot lamps, you will likely want to enable the UV Project Material Option (available in the materials panel), This uses a different UV interpolation to prevent distortion.

Note

This option is not yet available for Cycles.
