All of the cameras in my game are now entirely black and it’s hard to spot them if there’s nothing behind them. At first I thought I must have somehow changed the material applied to the mesh, but as you can see in the static mesh editor, it still has the default material. So why would all the camera actors in the game suddenly have a new material? Any idea how to get the old material back?
o.O
is it me or does it have some sort of green outline around it?
btw did you try on an empty map?
could also be the material applied to the mesh instance of the actor 
Ive seen strange thing happen with udk,similar (not the same).Sometimes what helps is to delete the UDKEngine from the config folder(it will be created a new one automatically when you start udk)+ a recompile of scripts.
Huh. This is really strange.
When I place a camera in a new map, it has the default material.
I cannot figure out how to place a material on the camera actor. I’ve tried dragging a material onto the mesh in the editor window and I’ve tried searching for material and static mesh component in the camera actor’s properties.
The green outline is because of a post-process effect. It’s the Sobel edge filter, but instead of drawing a pure black line, it saturates and darkens the scene color by multiplying the color by itself. During gameplay, the effect looks very different because it also multiplies by another color based on time of day.
I had another really odd bug a couple days ago when all of the landscape actors in my game suddenly disappeared. They were still in the levels when I played the game, and I could see them and select them in the Content Browser scene tab, but you could not see them at all in the game view window. I went into a new level, made a new landscape, and it showed up, and when I went back to my game’s level, all the landscapes were back.
My UE3 must be getting senile or something. I need to release this game soon, before its mind is completely gone.
I might just have to rebuild like O_and_N suggest. Thanks for taking a look.
ive had maps where part of the landscape would disappear from certain angles.just a gentle smoothing sorted it out.
I have to confess, I’m still using UDK February 2013. I found it as the less bugged version until now. I’m migrating my project to Unreal 4… (Yeah, I’m AmyP from UDK forums, some years ago.).
Hi @Amelia_P welcome back. Good luck on your project.
