This node evaluates a texture at specific coordinates
Inputs & Parameters¶
Parameters |
Description |
---|---|
Mapping |
Vectors mapping mode. Offers: UV Coordinates (with domain 0 to 1) and Object (with domain -1 to 1) |
Channel |
Color channel to output Offers: Red, Green, Blue, Hue, Saturation, Value, Alpha, RGB Average, Luminosity and Color |
Use Alpha |
Toggle to add alpha channel (Only when Channel is set to Color) |
Vertices |
Vertices of the mesh to displace |
Texture |
Texture(s) to use as base |

You can input multiple textures, when joined [[texture, texture,..],[..],..] they will be used in a single set of vertices with a single output list
