I was thinking of making something like a security camera in my scene
A mesh that looks like a camera renders an Envmap that is mapped to a mesh that looks like a computer screen.
After some tweaking I managed to get the picture to sit right on the screen.
Now the problem:
If I move the camera the picture changes correctly, but if I rotate the camera, the envmap is still rendered with the same viewpoint.
Is there any way to make the envmap rendered with respect to the rotation of the viewpoint? Or do I have to add a camera and render it seperately to use as a texture?
I’d rather not use the two-step process as I don’t have the hard-drive space to store the movies for every camera (the final scene will have about 5) and it adds to the rendering time.
