problem rotating an object in combustion

#1

i’m trying to align the black image into the building. but whenever i rotate it on the y axis, it doesn’t follow the pivot pointing downward but it rotates on the red pivot i drew. how can i correct this guys. thanks:)

As far as I know, rotations are always locked to an object’s pivot point. I can’t find any way to change that.
Matching objects up right with rotations in a 3d composite can kinda be a pain, since you have to continually adjust the value of rotation on each axis. Depending on what you’re doing though, you might want to look into four-corner objects (under composite controls->layer). You can get most of the rotation for the perspective down with the standard rotation transforms, and then simply move the object corners to get the ‘perfect’ match.
In a case like this though, you might make your life a little easier by moving your pivot point to the top edge of your object before doing any rotations. Then you can position your object close to (but not right beside) your background in 3d space, and the rotation will leave one of your edges in place. I think it makes the matching a little easier.
