Play with Texture

Hello, everyone. I want to know if it is possible to map specific triangle region of one texture to the another triangle of other texture with different size and shape in three.js?
I am new to three.js so I don’t know well how to implement it with three js code. Please help me. I need sample code snippet.

It’s possible but very tricky. You would have to somehow remove the triangle from the first model… then create a new model of just the triangle you want to swap, and use a different material on it.

This level of modification is most easily accomplished in a 3d modeller like blender.
