Whenever i enter a tardis the screen does a burn effect which reveals the tardis interior. The same happens when i exit. This causes quite a drop in frames and looks ugly. Is there a way to turn it off?

This sound like you have another mod installed. By any chance do you have that portal mod installed?

i have better portals yeah

i turned off better portals and it stopped, thanks for the help. Just curious, why does it do that?
