when i import my tetxures and use them on other materials they work just fine. they are all powers of 2 and square.
when i create a skybox and use them on the skybox they work fine too. BUT
when i create a cubemap, then assign my textures on the cubemap, then assign the cubemap to my skybox, the resolution is very very low.
Basically i cannot create a high-res cubemap? Does anyone knows why unity does this?
