UVs are an important part of the texturing process in the game industry. They determine how the texture will be laid out on the 3D model. If they are not straight, it can cause difficulty when trying to unwrap and apply textures. Maya has a built-in function to straighten UVs, but it can be time-consuming. The AriUVGridding Maya plug-in is a free tool that can quickly straighten UVs. It is very useful for game artists who are working in Maya.
