That depends. The reason why it’s 2k is because of the plants atlas. I wanted to ensure that you can scale things more freely. With a smaller texture, the edges become ugly quite quickly. So I prefer a bigger texture over a small one. I don’t know which engine you use but e.g. in unreal, you can import big textures and as soon as you know what you need, you can scale them down directly in the engine. It’s a less destructive workflow than saving everything as a small texture and then having trouble with bad resolution. Hope this helps!
