projecting an image
show user profile  zeefusion
is this possible to project an image over objects like it would be in real life? i have a wall with objects in front of it and i would like to project a screen on to the wall but also over the objects.

cheers

Sure, open the advanced effects rollout for the spotlight and add the image to the Projector map slot

okies done that but the light thats at an angle casts light on to the wall and still i get distortion, the projection light is straight but the angled light isnt.

the angled light will have a fog to it so when the fog hits the wall it will be at an angle and not flat like the actual projection light

Ok sorry for it being me that keeps replying but how about turning on shadows and putting a non rendering plane (with a trapezoid shaped hole in it) infront of the spot light so it only shows the light through the hole (you can change the view to the light's view and adjust the plane from there to get it spot on (maybe ;)

Real projectors have the same problem, they fix it buy distoring the image they project until it appears as undistorted on thhe wall, Could you do this somehow with what your projecting?

The effect you are describing is called key stoning. To tweak your image quickly, grab a screen capture from the perspective of your light. Put it in photoshop and use it's view of the screen to adjust your image... Hope this is making sense, it's really quite straightforward, but I haven't had my second cup of coffee yet. :/
