Render to texture not working. *cry*

[dendens2]

Hi, so I am trying to bake a light map by using render to texture. However, for some reason, whenever I render in a texture higher than256x256, it cuts off some portion of the map at the top. I do have the unwrap all in the box. This seems to just happen at random. I had this happen in 3dsmax 2013 on windows 7. I now have windows 8 and 3ds max 2014, but it is still doing it. I am, however, using the save from the former. Does ANYONE know why this is happening? THANKS!

FIGURED IT OUT. I just switched the map to a different channel and it works! 😄
