Custom campaign background screen

How do you use a custom background for a campaign screen? The campaign editor has an " from import" type of option, but it's grayed out. I'm assuming it wants me to import some type of file before I can point to it, but I have no idea what kind of file it wants me to import.

I tried making a map with a camera in it and imported that, but that's now what it's looking for.

Someone help please?

They are, AFAIK, model files.

Damn, that makes things complicated.

Anyone know what kind of camera the model file wants?

Cruise the MPQ and try to find one of the existing ones to use as a basis for creation.

TBH, AFAIR, [Dual Acronym Bonus +10!], campaign screens are messy and horrible to make. I know that they are all one big model. I THINK you just make them like you would a unit, and include a camera as if it were for a portrait, but IDK...

Yep, just a big model with a camera like any other.

Gotta remember to either make all the texures Unlit, or add a few lights in - else you'll get blackness no matter what.

big model, nah it doesn't pass 1-0 XY mesures, to make one, make a plane model in 3dsmax 5, copy it, then select the first one and make it a mesh and check the 2D model option, and the other one set it as a collition shape.

When aplying the texture make sure to unhide all, select model properties object (hotkey h for list), then enter its properties and go to user defined properties, roll down to Full Resolution and change it for true value.

PS IGNORE MY POST, I THOUGHT U MEAN LOADING BACKGROUND.
