Koru needs meshes to have texture mapping in order to apply textures to them. Sometimes models don’t have that mapping or have incorrect one. The UV Mapping tool helps you generate or correct the mapping, if necessary.
We’ll start with a koru model with incorrect texture mapping and a sample checkers texture applied:
As you may see, texture mapping is not perfect, as the front face doesn’t look mapped at all. Let’s fix it with UV Mapping tool. To do so, click the Tools -> Generate UV Mapping in the menu, or click the UV Mapping tool button in the toolbar. The UV Mapping generator window will pop up:
Note that the mapping in background becomes better. Here’s what you can configure:
Koru supports 4 standard mapping types: Box, Planar, Cylindrical and Spherical. For all the types (except the Box one) you can choose the main axis. For instance by selecting “Spherical Z” you choose the spherical mapping along the Z axis.
