Mapear UV

Map a texture using UV coordinates, to apply a texture to objects in compositing.

May be used in combination with Cryptomatte Node to apply the texture only to specific objects.

Inputs

Imagem

The new 2D texture.

UV

The input for UV render pass. See Cycles render passes.

Dica

To store the UV pass a multi-layer OpenEXR format could be used.

Properties

Filter Type

Métodos de interpolação.

Anisotropic:

Enhances the clarity of textures viewed at oblique angles, addressing issues like blurring and distortion.

Mais próximo:

No interpolation, uses nearest neighboring pixel.

Alfa

O ajuste de alfa é usado para esmaecer para o alfa os pixeis nas bordas das imagens.

Saídas

Imagem

A imagem resultante é a textura da imagem de entrada distorcida para combinar com as coordenadas UV. Esta imagem pode então ser sobreposta e misturada com a imagem original para a pintar a textura sobre a original.

Dica

Ao pintar com a nova textura, é uma boa ideia ter mapas UV para os objetos originais presentes na cena, e também é recomendado manter os contornos destas coordenadas UV de maneira distribuída, quando a tomada é feita.

Examples

In the example below, we have overlaid a grid pattern on top of the two heads after they have been rendered. During rendering, we enabled the UV layer in the Properties Render Layer ‣ Passes. Using a Mix node («Overlay» in figure), we mix that new UV texture over the original face. We can use this grid texture to help in any motion tracking that we need to do.

Adding a grid UV textures for motion tracking.

In the next example, we overlay a logo on top of a mesh composed of two intersecting cubes, and we ensure that we Enable the Alpha premultiply button on the Mix node. The logo is used as additional UV texture on top of the existing texture. Other examples include the possibility that there was used an unauthorized product box during the initial animation, and it is needed to substitute in a different product sponsor after rendering.

Dica

Due to limits of this node, it is not recommended to rush pre-production rendering under the guise of «fixing it later».
