Editing Textures - disappear at a certain range

[nico2077]

So basically I know how to edit textures there's just one thing that bugs me: when I'm flying too far away from a building with a custom billboard (for example) it disappears and the old, custom texture appears again: It's not that big of a deal but I would appreciate your help.

I normally edit all .ytd and .ytr files that contain the texture I want to replace. Please tell me if I can fix this somehow or if this is a normal issue with custom textures

Thanks in advance
