is it possible to cut up these islands so that i can fit them into the trimsheet area. tried alt-Y but it just causes seams in the texture. https://cdn.discordapp.com/attachments/1479841983013978263/1479841983651516568/split.jpg?ex=69ad81bf&is=69ac303f&hm=933a29a449eea42d5dc2987d81608d7a774fdf7ad07126216806399cbeb931a4&

It all depends on what you want to do. In the simplest case, select the polygons that should become a separate island and press V. Then drag them to the side. If you already know exactly what division you need to achieve and you need more than two islands, it makes sense to use the Zen Unwrap operator. I warn you that in this case, it is better to review the tutorial. https://zenmastersteam.github.io/Zen-UV/latest/tutorial/ The new islands will have a chaotic orientation, so use the World Orient operator after the split. https://zenmastersteam.github.io/Zen-UV/latest/transform/#world-orient https://cdn.discordapp.com/attachments/1479841983013978263/1479875653393191024/image.png?ex=69ada11a&is=69ac4f9a&hm=9997eda907ca012175a4830b268901852eb3d48712d9dae9e429bd3297aa03f9&
